The root view controller of navigation controller supports only portrait orientation and other controllers supports all orientation.Now if i am on the root view controller and the DEVICES is in landscape and if i push next view controller that opens in portrait that should open in landscape as it supports all orientation.
Please help me with this.
Using iPhone 4s iOS6.1.3
you can check Device orientation in your first screen after login viewcontroller using bellow code:-
-(void)viewWillAppear:(BOOL)animated
{
[self willRotateToOrientation:[[UIDevice currentDevice] orientation]];
[super viewWillAppear:YES];
}
- (void)willRotateToOrientation:(UIInterfaceOrientation)newOrientation {
if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation))
{
if (newOrientation == UIInterfaceOrientationLandscapeLeft || newOrientation == UIInterfaceOrientationLandscapeRight) {
//set your landscap View Frame
[self supportedInterfaceOrientations];
}
}
else if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation))
{
if(newOrientation == UIInterfaceOrientationPortrait || newOrientation == UIInterfaceOrientationPortraitUpsideDown){
//set your Potrait View Frame
[self supportedInterfaceOrientations];
}
}
// Handle rotation
}
sor when you load this viewcontroller it check first device oriantation and then load it's related frame
I think this is the issue related to the orientation changes in iOS6. You need to subclass the UINavigationController
Check this
1 . You have to create sub class of UINavigationController. add Following method.. Take one boolean variable to check whether it support for all orientation or not and change its value.
#implementation NavigationControllerViewController
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
AppDelegate *appdelgate=[[UIApplication sharedApplication]delegate];
if (appdelgate.issuppoertAll) {
// for iPhone, you could also return UIInterfaceOrientationMaskAllButUpsideDown
return UIInterfaceOrientationMaskAll;
}
return UIInterfaceOrientationMaskPortrait;
}
#end
2 when you navigate form root view controller to other view controller
use this code , when you want to forcefully change its orientation.i.e lanscape to portrait
obj_viewcontroller = [[SecondViewController alloc] initWithNibName:#"SecondViewController" bundle:nil];
[self presentModalViewController:obj_viewcontroller animated:NO];
[self dismissModalViewControllerAnimated:NO];
[self.navigationController pushViewController:obj_viewcontroller animated:NO];
3 In second view controller you have to change boolean variable value
-(void)viewWillAppear:(BOOL)animated
{
appdelgate.issuppoertAll=YES;
}
4 Add this method into all view controller and set orientation as per your need.
- (NSInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
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.

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 );
}
}
}
}
Lets say I have three UI Controllers (A,B,C).
A is my root controller and inside the ShouldAutoRotate method I return YES.
I do presentModalView from A to B (B=>inside the ShouldAutoRotate method I return Portrait) then from B I do presentModal to C (C should be able to rotate to any orientation).
Now inside C I'm able to rotate the simulator to any orientation, and the whole View rotates perfectly.Here is the problem, when C is Landscape and I dismiss it, all the objects inside B will become messed up!! same thing happens to A.
I just need to have the rotation on C!!
Gratitudes.
In App delegate
#interface AppDelegate : UIResponder <UIApplicationDelegate>
#property (nonatomic) BOOL shouldRotate;
#end
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
if (self.shouldRotate == YES) {
return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskPortrait;
}
return UIInterfaceOrientationMaskPortrait;
}
In viewController A,B
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
((AppDelegate *)[[UIApplication sharedApplication] delegate]).shouldRotate = NO;
[self supportedInterfaceOrientations];
[self shouldAutorotate:UIInterfaceOrientationPortrait];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (BOOL)shouldAutorotate:(UIInterfaceOrientation)interfaceOrientation{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
In viewController C
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
((AppDelegate *)[[UIApplication sharedApplication] delegate]).shouldRotate = YES;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
- (BOOL)shouldAutorotate:(UIInterfaceOrientation)interfaceOrientation{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait|UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}
- (IBAction)closeVC:(id)sender {
NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
[[UIDevice currentDevice] setValue:value forKey:#"orientation"];
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
appDelegate.shouldRotate = NO;
[self supportedInterfaceOrientations];
[self shouldAutorotate:UIInterfaceOrientationPortrait];
[self dismissViewControllerAnimated:YES completion:nil];
}
Hope this solves your problem
You need to allow all orientations from project info
and then override implement all these methods to target iOS 6 + in each view controller to enable and disable orientation.
supportedInterfaceOrientations
shouldAutorotate
shouldAutorotateToInterfaceOrientation
force rotate C to portrait before you dismiss it
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
I have a navigation controller app. And first I push FirstViewController (support Portrait orientation) and then SecondViewController (supports all orientations). When I'm in landscape mode of SecondViewController and press back button, FirstViewController appears in landscape mode. That's why I manually rotate the navigation view, but when I want to set setStatusBarOrientation to Portrait (First view controller should appears only in portrait mode), the orientation of view controller is still landscape, and even if rotate the device to portrait mode, the orientation stay landscape
.Here is my code of FirstViewController:
- (void)viewWillAppear:(BOOL)animated
{
if (UIInterfaceOrientationIsLandscape(self.interfaceOrientation))
{
if (self.interfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
prevInterfaceOrientation = UIInterfaceOrientationLandscapeLeft;
self.navigationController.view.transform = CGAffineTransformIdentity;
self.navigationController.view.transform =
CGAffineTransformMakeRotation(degreesToRadians(90));
}
else if (self.interfaceOrientation ==
UIInterfaceOrientationLandscapeRight) {
prevInterfaceOrientation = UIInterfaceOrientationLandscapeRight;
self.navigationController.view.transform = CGAffineTransformIdentity;
self.navigationController.view.transform =
CGAffineTransformMakeRotation(degreesToRadians(-90));
}
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:NO];
[self.tableViewDetail reloadData];
}
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
if (toInterfaceOrientation == UIInterfaceOrientationPortrait)
{
if (prevInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) {
self.navigationController.view.transform = CGAffineTransformIdentity;
}
else if (prevInterfaceOrientation ==
UIInterfaceOrientationLandscapeRight) {
self.navigationController.view.transform = CGAffineTransformIdentity;
}
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];
[self.tableViewDetail reloadData];
}
}
I even tried to use:
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
if (UIInterfaceOrientationIsLandscape(prevInterfaceOrientation))
{
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];
}
}
but self.interfaceOrientation still stays landscape, when I rotate to portrait.
But I really need to rotate the view to portrait mode manually to allow users to see,that FirstViewController suppors only portrait orientation.
I have the option to put the SecondViewController's view on MainWindow (like modal window), but I don't like this idea, because if apple has setStatusBarOrientation method, it seems to me, that it has to be right solve of this issue.
I would get rid of the transformations, and use
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:animated];
This in combination with the forced redrawing of the view stack will get it done. This can be done by adding the following to viewDidAppear to the first controller (it doesn't work in viewWillApear).
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
UIWindow *window = [[UIApplication sharedApplication] keyWindow];
if ([window.subviews count] > 0) {
UIView *view = [window.subviews objectAtIndex:0];
[view removeFromSuperview];
[window insertSubview:view atIndex:0];
}
else {
DLog(#"NO view to force rotate?");
}
Unfortunately, the transition animation is not very clean when you do this, so I would recommend taking a snapshot of the portrait screen, overlay this over your view, and then fade it out with a separate animation.
Steven Veltema's answer didn't work for me.
I had one view controller where all orientations where allowed, and the rest only supported portrait. When i had the first view controller in landscape and navigated to another view controller, the orientation didn't refresh as you are experiencing.
I found another trick to reload the views i correct orientation. Just add a modal view controller you don't even see it. Add this in all other views:
- (void)viewDidAppear:(BOOL)animated
{
UIInterfaceOrientation interfaceOrientation = [[UIApplication sharedApplication] statusBarOrientation];
if(UIInterfaceOrientationIsLandscape(interfaceOrientation)){
UIViewController * viewController = [[UIViewController alloc] init];
[self presentModalViewController:viewController animated:NO];
[viewController dismissModalViewControllerAnimated:NO];
}
[super viewDidAppear:animated];
....
}
Another quick solution is
Click on your project in the left side bar.
In General settings, choose "Hide during application launch" option.
My app must NOT auto-rotate at all. But it includes a screen which tells the user to rotate his phone (and not the opposite!).
To do that, the ViewController must make an animated rotation (without any rotation event) when the screen is displaying.
So I used
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:animated];
}
- (void)viewWillDisappear:(BOOL)animated {
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait animated:animated];
[super viewWillDisappear:animated];
}
And
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return YES;
}
to make my screen rotate, as every website and documentation recommend.
But only the StatusBar rotates: my NavigationBar remains stuck at the top.
I would use a CGAffineTransform perhaps on the navigationcontroller view? Simply rotate it using an animation block 90 degrees?
this code is helpful for you to resize the navigation bar automatically you can use it in where you create the navigationController & navigation bar
self.navigationController.navigationBar.autoresizesSubviews = YES;
self.navigationController.navigationBar.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
above code will work automatically if it is not then you try this will work in all delegates methods of your view controller where you need the change
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft animated:animated];
[self.navigationController shouldAutorotateToInterfaceOrientation:[UIApplication sharedApplication].statusBarOrientation];
}
- (void) didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
CGRect frame = self.navViewController.navigationBar.frame;
frame.size = self.view.frame.size;
if (toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
frame.size.height = 44;
} else {
frame.size.height = 32;
}
self.navViewController.navigationBar.frame = frame;
if navigation controller is rootview controller then check it enables the all orientation supports
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
[super shouldAutorotateToInterfaceOrientation:toInterfaceOrientation];
[self.navigationController shouldAutorotateToInterfaceOrientation:toInterfaceOrientation];
return YES;
}
you can use this code in viewcontroller delegates listed below according to your requirment
- (void)viewDidAppear:(BOOL)animated
- (void)viewWillAppear:(BOOL)animated
– willRotateToInterfaceOrientation:duration:
– willAnimateRotationToInterfaceOrientation:duration:
– didRotateFromInterfaceOrientation:
