I have an app that works in all directions.
For iOS 6 I use
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
And for iOS 5
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
This part seems to work.
Then, because I want to stop the rotation animation, I implement these methods:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
[super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
[UIView setAnimationsEnabled:NO];
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
[super didRotateFromInterfaceOrientation:fromInterfaceOrientation];
[UIView setAnimationsEnabled:YES];
}
Everything is OK, but if I show an UIAlert and then the device rotates, the background black shadows appears in the wrong direction.
This happens only in iOS 6 and not on iOS 5, on the actual device and in the simulator, and only if I prevent the rotation from animating.
Any idea?
EDIT: Here my rootViewController
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Other things
self.rootViewController = [[[RootViewController alloc] initWithNibName:#"RootViewController" bundle:[NSBundle mainBundle]] autorelease];
self.window.rootViewController = self.rootViewController;
[self.window makeKeyAndVisible];
return YES;
}
Window is stored in NIB.
To close this question...
I don't know what was the problem causing this issue, I suppose something related to iOS version.
I solved it by implementing my custom alert (a subclass of UIViewController).

I used this code to block the rotation before ios 7 (i was also using xibs, now storyboard)
- (BOOL)shouldAutorotate {
return NO;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationPortrait;
}
now that i migrated to storyboard and ios7 it is not working, my view is still rotating.
UPDATE:
I solved this by adding this code to the delegate, now my previous code works like charm
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
NSUInteger orientations = UIInterfaceOrientationMaskPortrait;
if (self.fullScreenVideoIsPlaying) {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
else {
if(self.window.rootViewController){
UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presentedViewController supportedInterfaceOrientations];
}
return orientations;
}
Atrik's code worked. Here is a more complete solution which allows locking and unlocking of portrait-mode-only even with the use of UINavigationController
appdelegate .h
#property (nonatomic) BOOL screenIsPortraitOnly;
appdelegate .m
#pragma mark - View Orientation
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
NSUInteger orientations = UIInterfaceOrientationMaskPortrait;
if (self.screenIsPortraitOnly) {
return UIInterfaceOrientationMaskPortrait;
}
else {
if(self.window.rootViewController){
UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presentedViewController supportedInterfaceOrientations];
}
return orientations;
}
}
For all view controllers where I need Portrait Lock
If you haven't used a subclass which has the app delegate imported then don't forget to import the delegate. For most view controllers I use a subclass of UIViewController which at least does importation.
#import "AppDelegate.h"
I use this for all portrait locked viewcontrollers.
-(void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:true];
[self portraitLock];
}
-(void) portraitLock {
AppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
appDelegate.screenIsPortraitOnly = true;
}
#pragma mark - interface posiiton
- (NSUInteger) application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL) shouldAutorotate {
return NO;
}
ViewDidLoad runs before viewDidAppear so I run this in my subclass of UIViewController to unlock all screens. The viewWillAppear with the lock method is used only in the cotrollers which I need to lock the screen.
- (void)viewDidLoad
{
[super viewDidLoad];
[self portraitUnLock];
}
-(void) portraitUnLock {
AppDelegate* appDelegate = [UIApplication sharedApplication].delegate;
appDelegate.screenIsPortraitOnly = false;
}
If you only want in landscape mode then you can do it with xcode project setting
go to Target > summary > support interface orientations
Or you can do a code
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations.
return (UIInterfaceOrientationIsLandscape(interfaceOrientation));
}
In XCode 5, which is required to be used for iOS7 development, you can go to your target and under Deployment Info uncheck everything except Portrait for device orientation.
If you don't want your app to rotate at all (no matter which view is active), you can click on your project in the Xcode sidebar, scroll down, and deselect Landscape Left and Landscape Right.
I have an app which has 2 view controllers. The first viewcontroller should be in portrait and it's ok, but when I'm loading the second view controller, I could not make the app orientation to be landscape... The problem is with iOS 6.
I have tried everything I found on SO.
Using [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight animated:NO]; on viewWillAppear and viewDidLoad,
and also:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if (interfaceOrientation == UIInterfaceOrientationPortrait) {
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
} else {
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
}
-(BOOL)shouldAutorotate
{
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
-(NSInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscapeRight;
}
Add these code in 2nd View Controller's viewDidLoad method to transform view into landscape :
[self rotateController:self degrees:-90];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:NO];
//set it according to 3.5 and 4.0 inch screen in landscape mode
[self.view setBounds:CGRectMake(0, 0, 480, 320)];
add rotateController method :
-(void) rotateController:(UIViewController *)controller degrees:(NSInteger)aDgrees
{
UIScreen *screen = [UIScreen mainScreen];
if(aDgrees>0)
controller.view.bounds = CGRectMake(0, 0, screen.bounds.size.height, screen.bounds.size.width);
else
{
controller.view.bounds = CGRectMake(0, 0, screen.bounds.size.width, screen.bounds.size.height);
}
controller.view.transform = CGAffineTransformConcat(controller.view.transform, CGAffineTransformMakeRotation(DEGREES_TO_RADIANS(aDgrees)));
}
Now in viewWillDisappear's method to transform view into protrait . Add these:
[self rotateController:self degrees:90];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
//set it according to 3.5 and 4.0 inch screen in protrait mode
[self.view setBounds:CGRectMake(0, 0, 320, 480)];
Also your orientation methods should be like these if not added add these :
- (BOOL)shouldAutorotate
{
//make view landscape on start
return NO;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeLeft;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
EDIT : Add these macro for radian
#define DEGREES_TO_RADIANS(angle) ((angle) / 180.0 * M_PI)
you may add this code on this view controller where you want to fix your orientation
Code as Below
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPhone)
{
return UIInterfaceOrientationMaskPortrait;
}
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
if(UI_USER_INTERFACE_IDIOM()==UIUserInterfaceIdiomPhone)
{
return (toInterfaceOrientation==UIInterfaceOrientationPortrait);
}
}
and second view controller you may want to rotate all orientation then not necessary to adding any code ios6 will manage the orientation automatically.
You need to select the landscape mode in application summary-> deployment info.
Also if you are using xib file to design the UI, you need to set the orientation of second view controller to landscape
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
-(BOOL)shouldAutorotate
{
return NO;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
-(NSInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight;
}
You were not returning the NO in the method shouldAutorotate , replace you existing code with this .
Hope it will help you.
Prior to iOS 6 i.e in iOS 5 and earlier, an app and a view controller’s rotation is controlled by the individual viewcontrollers while in iOS 6 and later, the view controllers responsible for rotation are the container Viewcontrollers such as UINavigationController & UITabBarController . What are you using as the rootviewcontroller in your project??
Autorotation is clearly explained here in this post- Autorotation in iOS
I gave an app with say 10 view controllers. I use navigation controller to load/unload them.
All but one are in portrait mode. Suppose the 7th VC is in landscape. I need it to be presented in landscape when it gets loaded.
Please suggest a way to force the orientation go from portrait to landscape in IOS 6 (and it will be good to work in IOS 5 as well).
Here is how I was doing it BEFORE IOS 6:
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
UIViewController *c = [[[UIViewController alloc]init] autorelease];
[self presentModalViewController:c animated:NO];
[self dismissModalViewControllerAnimated:NO];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
Presenting and dismissing a modal VC was forcing the app to review its orientation, so shouldAutorotateToInterfaceOrientation was getting called.
What I have have tried in IOS 6:
- (BOOL)shouldAutorotate{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskLandscape;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationLandscapeLeft;
}
On load, the controller keeps staying in portrait. After rotating the device, the orientation changes just ok. But I need to make the controller to rotate automatically to landscape on load, thus the user will have to rotate the device to see the data correctly.
Another problem: after rotating the device back to portrait, the orientation goes to portrait, although I have specified in supportedInterfaceOrientations only UIInterfaceOrientationMaskLandscape. Why it happens?
Also, NONE of above 3 methods are getting called.
Some (useful) data:
In my plist file I have specified 3 orientations - all but upside down.
The project was started in Xcode 4.3 IOS 5. All classes including xibs were created before Xcode 4.5 IOS 6, now I use the last version.
In plist file the status bar is set to visible.
In xib file (the one I want to be in landscape) the status bar is "None", the orientation is set to landscape.
Any help is appreciated. Thanks.
Ok, folks, I will post my solution.
What I have:
A view based application, with several view controllers. (It was navigation based, but I had to make it view based, due to orientation issues).
All view controllers are portrait, except one - landscapeLeft.
Tasks:
One of my view controllers must automatically rotate to landscape, no matter how the user holds the device. All other controllers must be portrait, and after leaving the landscape controller, the app must force rotate to portrait, no matter, again, how the user holds the device.
This must work as on IOS 6.x as on IOS 5.x
Go!
(Update Removed the macros suggested by #Ivan Vučica)
In all your PORTRAIT view controllers override autorotation methods like this:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
-(BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
You can see the 2 approaches: one for IOS 5 and another For IOS 6.
The same for your LANDSCAPE view controller, with some additions and changes:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
[image_signature setImage:[self resizeImage:image_signature.image]];
return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
-(BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
[image_signature setImage:[self resizeImage:image_signature.image]];
return UIInterfaceOrientationMaskLandscapeLeft;
}
ATTENTION: to force autorotation in IOS 5 you should add this:
- (void)viewDidLoad{
[super viewDidLoad];
if ([[[UIDevice currentDevice] systemVersion] floatValue] < 6.0)
[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationLandscapeLeft animated:NO];
}
Analogically, after you leave the LANDSCAPE controller, whatever controller you load, you should force again autorotation for IOS 5, but now you will use UIDeviceOrientationPortrait, as you go to a PORTRAIT controller:
- (void)viewDidLoad{
[super viewDidLoad];
if ([[[UIDevice currentDevice] systemVersion] floatValue] < 6.0)
[[UIApplication sharedApplication] setStatusBarOrientation:UIDeviceOrientationPortrait animated:NO];
}
Now the last thing (and it's a bit weird) - you have to change the way you switch from a controller to another, depending on the IOS:
Make an NSObject class "Schalter" ("Switch" from German).
In Schalter.h say:
#import <Foundation/Foundation.h>
#interface Schalter : NSObject
+ (void)loadController:(UIViewController*)VControllerToLoad andRelease:(UIViewController*)VControllerToRelease;
#end
In Schalter.m say:
#import "Schalter.h"
#import "AppDelegate.h"
#implementation Schalter
+ (void)loadController:(UIViewController*)VControllerToLoad andRelease:(UIViewController*)VControllerToRelease{
//adjust the frame of the new controller
CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame];
CGRect windowFrame = [[UIScreen mainScreen] bounds];
CGRect firstViewFrame = CGRectMake(statusBarFrame.origin.x, statusBarFrame.size.height, windowFrame.size.width, windowFrame.size.height - statusBarFrame.size.height);
VControllerToLoad.view.frame = firstViewFrame;
//check version and go
if (IOS_OLDER_THAN_6)
[((AppDelegate*)[UIApplication sharedApplication].delegate).window addSubview:VControllerToLoad.view];
else
[((AppDelegate*)[UIApplication sharedApplication].delegate).window setRootViewController:VControllerToLoad];
//kill the previous view controller
[VControllerToRelease.view removeFromSuperview];
}
#end
NOW, this is the way you use Schalter ( suppose you go from Warehouse controller to Products controller ) :
#import "Warehouse.h"
#import "Products.h"
#implementation Warehouse
Products *instance_to_products;
- (void)goToProducts{
instance_to_products = [[Products alloc] init];
[Schalter loadController:instance_to_products andRelease:self];
}
bla-bla-bla your methods
#end
Of course you must release instance_to_products object:
- (void)dealloc{
[instance_to_products release];
[super dealloc];
}
Well, this is it. Don't hesitate to downvote, I don't care. This is for the ones who are looking for solutions, not for reputation.
Cheers!

This should work, it's similar to the pre-iOS 6 version, but with a UINavigationController:
UIViewController *portraitViewController = [[UIViewController alloc] init];
UINavigationController* nc = [[UINavigationController alloc] initWithRootViewController:portraitViewController];
[self.navigationController presentModalViewController:nc animated:NO];
[self.navigationController dismissModalViewControllerAnimated:NO];
I'm calling this before I'm pushing the next UIViewController. It will force the next pushed UIViewController to be displayed in Portrait mode even if the current UIViewController is in Landscape (should work for Portrait to Landscape too). Works on iOS 4+5+6 for me.
I think that best solution is to stick to official apple documentation. So according to that I use following methods and everything is working very well on iOS 5 and 6.
In my VC I override following methods:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return UIInterfaceOrientationIsPortrait(interfaceOrientation);
}
Methods for iOS 6, first method returns supported orientation mask (as their name indicate)
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
second one thats tells your VC which is preferred interface orientation when VC is going to be displayed.
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
Just change Portrait for orientation that you want ;)
This solution is working smooth, I don't like the idea of creating macros and other stuff, that goes around this simple solution.
Hope this help...
I had the same problem, 27 views in my application from which 26 in portrait and only one in all orientations ( an image viewer :) ).
Adding the macro on every class and replace the navigation wasn't a solution I was comfortable with...
So, i wanted to keep the UINavigationController mechanics in my app and not replace this with other code.
What to do:
#1 In the application delegate in method didFinishLaunchingWithOptions
if ([[UIDevice currentDevice].systemVersion floatValue] < 6.0)
{
// how the view was configured before IOS6
[self.window addSubview: navigationController.view];
[self.window makeKeyAndVisible];
}
else
{
// this is the code that will start the interface to rotate once again
[self.window setRootViewController: self.navigationController];
}
#2
Because the navigationController will just responde with YES for autorotation we need to add some limitations:
Extend the UINavicationController -> YourNavigationController and link it in the Interface Builder.
#3 Override the "anoying new methods" from navigation controller.
Since this class is custom only for this application it can take responsibility
for it's controllers and respond in their place.
-(BOOL)shouldAutorotate {
if ([self.viewControllers firstObject] == YourObject)
{
return YES;
}
return NO;
}
- (NSUInteger)supportedInterfaceOrientations {
if ([self.viewControllers firstObject] == YourObject)
{
return UIINterfaceOrientationMaskLandscape;
}
return UIInterfaceOrientationMaskPortrait;
}
I hope this will help you,
From the iOS 6 Release Notes:
Now, iOS containers (such as UINavigationController) do not consult their children to determine whether they should autorotate.
Does your rootViewController pass the shouldAutoRotate message down the ViewController hierarchy to your VC?
I used the same method as OP pre-ios6 (present and dismiss a modal VC) to show a single view controller in landscape mode (all others in portrait). It broke in ios6 with the landscape VC showing in portrait.
To fix it, I just added the preferredInterfaceOrientationForPresentation method in the landscape VC. Seems to work fine for os 5 and os 6 now.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
- (BOOL)shouldAutorotate
{
return NO;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
Hey guys after tryng a lot of different possible solutions with no success i came out with the following solution hope it helps!.
I prepared a recipe :).
Problem:
you need change orientation of viewcontrollers using navigationcontroller in ios 6.
Solution:
step 1. one initial UIviewcontroler to trigger modal segues to landscape and
portrait UInavigationControllers as picture shows....
more deeply in UIViewController1 we need 2 segues actions according to global variable at Appdelegate....
-(void)viewDidAppear:(BOOL)animated{
if([globalDelegate changeOrientation]==0){
[self performSegueWithIdentifier:#"p" sender:self];
}
else{
[self performSegueWithIdentifier:#"l" sender:self];
}
}
also we need a way back to portrait &| landscape....
- (IBAction)dimis:(id)sender {
[globalDelegate setChangeOrientation:0];
[self dismissViewControllerAnimated:NO completion:nil];
}
step 2. the first Pushed UiViewControllers at each NavigationController goes
with...
-(NSUInteger)supportedInterfaceOrientations{
return [self.navigationController supportedInterfaceOrientations];
}
-(BOOL)shouldAutorotate{
return YES;
}
step 3. We overwrite supportedInterfaceOrientations method at subclass of UInavigationController....
in your customNavigationController we have .....
-(NSUInteger)supportedInterfaceOrientations{
if([self.visibleViewController isKindOfClass:[ViewController2 class]]){
return UIInterfaceOrientationMaskPortrait;
}
else{
return UIInterfaceOrientationMaskLandscape;
}
}
step 4. At storyboard or by code, set wantsFullScreenLayout flag to yes, to both portrait and landscape uinavigationcontrollers.
Try segueing to a UINavigationController which uses a category or is subclassed to specify the desired orientation, then segue to the desired VC. Read more here.
As an alternative you can do the same using blocks:
UIViewController *viewController = [[UIViewController alloc] init];
viewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:viewController animated:NO completion:^{
[self dismissViewControllerAnimated:NO completion:nil];
}];
Also, call it before pushing the new view.
Go to you Info.plist file and make the change
I had the same problem. If you want to force a particular view controller to appear in landscape, do it right before you push it into the navigation stack.
UIInterfaceOrientation currentOrientation = [[UIApplication sharedApplication] statusBarOrientation];
if (currentOrientation == UIInterfaceOrientationPortrait ||
currentOrientation == UIInterfaceOrientationPortraitUpsideDown)
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeLeft];
UIViewController *vc = [[UIViewController alloc] init];
[self.navigationController pushViewController:vc animated:YES];
[vc release];
I solved it by subclassing UINavigationController and overriding the supportedInterfaceOrientations of the navigation Controller as follow:
- (NSUInteger)supportedInterfaceOrientations
{
return [[self topViewController] supportedInterfaceOrientations];
}
All the controllers implemented supportedInterfaceOrientations with their desired orientations.
I have used the following solution. In the one view controller that has a different orientation than all the others, I added an orientation check in the prepareForSegue method. If the destination view controller needs a different interface orientation than the current one displayed, then a message is sent that forces the interface to rotate during the seque.
#import <objc/message.h>
...
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if(UIDeviceOrientationIsLandscape(self.interfaceOrientation))
{
UIInterfaceOrientation destinationOrientation;
if ([[segue destinationViewController] isKindOfClass:[UINavigationController class]])
{
UINavigationController *navController = (UINavigationController *)[segue destinationViewController];
destinationOrientation = [navController.topViewController preferredInterfaceOrientationForPresentation];
} else
{
destinationOrientation = [[segue destinationViewController] preferredInterfaceOrientationForPresentation];
}
if ( destinationOrientation == UIInterfaceOrientationPortrait )
{
if ([[UIDevice currentDevice] respondsToSelector:#selector(setOrientation:)])
{
objc_msgSend([UIDevice currentDevice], #selector(setOrientation:), UIInterfaceOrientationPortrait );
}
}
}
}
Background: App has a shake to go home feature. Home view Only supports portrait.
If you shake a bit harder than usual, the view that you are on starts to rotate (which is fine) , but then it detects a shake and does a popViewControlller to the home view. When it does this it loads the navigation controller just fine, but the view under (the home content) gets loaded behind the bar and is stretched up (it's basically loading underneath the navigation bar, so it gets stretched up)
The back button handles this just fine from landscape to portrait (since its not mid transitions)
How should I go about handling this orientation change (from the shake) so I can pop back into the root view controller, without the view loading under the navigation bar?
Edit:What's happening is the content thinks that it has the entire view to load, so it stretches itself to take the entire screen, not realizing theres a navigationbar above it. I can tell since the images loading are stretched out
added a bounty of 50.
Edit Here's How I'm detecting Shakes and Popping
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if ( event.subtype == UIEventSubtypeMotionShake )
{
UINavigationController *navController = self.navigationController;
[[self retain] autorelease];
HomeViewController *home = [[HomeViewController alloc]init];
[navController popViewControllerAnimated:YES];
home.title =#"Home View Controller";
[home release];
}
if ( [super respondsToSelector:#selector(motionEnded:withEvent:)] )
[super motionEnded:motion withEvent:event];
}
Here's my App Delegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
navController = [[UINavigationController alloc]init];
[self.window addSubview:navController.view];
HomeViewController *home = [[HomeViewController alloc]init];
[[self home] setFrame:[[UIScreen mainScreen] applicationFrame]];
I'll include a mockup here.
Normal View:
Stretched View After a Shake/Pop:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
// Return YES for supported orientations
return YES;
}
I'm a bit puzzled by your code so I'd really suggest starting from the beginning. As Lukya mentioned, there's no reason to recreate the HomeViewController. I'm also baffled by the "[[self retain] autorelease];" bit. That shouldn't be necessary unless you're doing something incorrectly elsewhere.
So I would start with this... In application:didFinishLaunchingWithOptions: do something like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
HomeViewController *home = [[[HomeViewController alloc] init] autorelease];
UINavigationController *navController = [[[UINavigationController alloc] initWithRootViewController:home] autorelease];
[self.window addSubview:navController.view];
}
The window will retain a your nav controller and the nav controller will retain your HomeViewController.
Then in motionEnded:withEvent: do something like:
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if (event.subtype == UIEventSubtypeMotionShake)
{
[self.navigationController popViewControllerAnimated:YES];
}
}
That should be it.
If that does not work then can you give any other info? For example, does HomeViewController implement (and return YES) in shouldAutorotateToInterfaceOrientation:? If so, can you return no so it doesn't rotate since your first line says "Home view Only supports portrait"?
Edit: An example of willRotateToInterfaceOrientation:duration: and didRotateFromInterfaceOrientation: as well.
In the header for whatever controller you're detecting shakes in add a boolean:
BOOL isRotating;
In your implementation file add the two UIViewController methods we want to override -- something like:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
[super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
isRotating = YES;
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
[super didRotateFromInterfaceOrientation:fromInterfaceOrientation];
isRotating = NO;
}
Now, do something like this for your event handler:
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if (event.subtype == UIEventSubtypeMotionShake && !isRotating)
{
[self.navigationController popViewControllerAnimated:YES];
}
}
in your home view controller's xib, go to the inspector for the view and set top bar as navigation bar.. and in view did load set self.navigationBarHidden = NO;...
NOTE:
there are many thing wrong with the code you've posted.. but none of them causes the orientation problem... in fact this seems to be the only code you need in that method:
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if (event.subtype == UIEventSubtypeMotionShake)
{
[navController popViewControllerAnimated:YES];
}
}
so you might want to change this code as well..
Have you tried calling [[UIApplication sharedApplication] setStatusBarOrientation: UIInterfaceOrientationPortrait animated:YES]; in your home view controller? You could also try to place this in where you detect a shake.
I have come across this issue with underlapping the navigation bar. I am not sure what causes it but you can work around it by calling,
[[self loadingView] setFrame:[[UIScreen mainScreen] applicationFrame]];
after the problem view is added to window in the application delegate.
I have made a view based application which is loading a default view ...
My default view is a splash screen ..
What I want to achieve is once default view (splash view) finished loading, after few seconds it loads another view which is either a privacy policy or application screen.
Code in AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
No Change as usual ...
Above code load a view from splashscreen.xib file
Following code is in splashscreen.m
- (IBAction)loadPrivacyScreen {
NSLog(#"Switching To Another View");
PrivacyPolicyView *modal = [[PrivacyPolicyView alloc]initWithNibName:nil bundle:nil];
modal.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:modal animated:YES];
[modal release];
}
- (void)viewDidLoad {
[super viewDidLoad];
sleep(3);
[self loadPrivacyScreen];
// Do any additional setup after loading the view from its nib.
}
After three second it does get in to the loadPrivacyScreen funciton but doesn't load the view.
- (IBAction)loadPrivacyScreen;
I have created a method as IBAction because I want to hook that method with a button on privacy screen to check that function works ...
And surprisingly it works when you click the button. But it doest work on time.
Can anyone suggest me what am I doing wrong ?? or any other alternative to achieve same thing??
Note: I have also try changing
- (IBAction)loadPrivacyScreen;
to
- (void)loadPrivacyScreen;
But still same result. It is not switching ....
First of all iOS provides a simple way to load a splash screen.
Just add a Image with 320x480 resolution in the name called default.png and add that to your project it will automatically use this image as splash screen image.
In your way call the loadPrivacy screen with a timer.
- (void)viewDidLoad {
[super viewDidLoad];
NSTimer *theTimer = [NSTimer scheduledTimerWithTimeInterval:3.00 target:self selector:#selector(loadPrivacyScreen) userInfo:nil repeats:NO];
}
- (void)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
[viewController showSplash];
}
And in the view controller, define a method like
> IBOutlet UIView *modelView;
- (void)showSplash;
- (void)hideSplash;
-(void)showSplash {
UIViewController *modalViewController = [[UIViewController alloc] init];
modalViewController.view = modelView;
[self presentModalViewController:modalViewController animated:NO];
[self performSelector:#selector(hideSplash) withObject:nil afterDelay:2.0];
}
//hide splash screen
- (void)hideSplash {
[[self modalViewController] dismissModalViewControllerAnimated:YES];
}
