I have UiNavigationController in my app.
I want that only one screen will be able to rotate so i put in this class :
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
return YES;
}
-(BOOL)shouldAutorotate {
return YES;
}
-(NSInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAll;
}
but the problem that happen is in ecery screen the app the rotation happens. how i can disable it?
For iOS 6, I am using the following code in my app, which allows you to specify rotation for each viewcontroller individually:
AppDelegate.m -
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{NSUInteger orientations =UIInterfaceOrientationMaskAllButUpsideDown;
if(self.window.rootViewController){
UIViewController *presentedViewController = [[(UINavigationController *)self.window.rootViewController viewControllers] lastObject];
orientations = [presentedViewController supportedInterfaceOrientations];
}
return orientations;
}
ViewController.m -
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
Credits for the code originially I believe go to the Ray Wenderlich "iOS 6 by Tutorials" book. Ray Wenderlich website
Use the below code in the class you want to autorotate only:
#interface UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;
- (NSUInteger)supportedInterfaceOrientations;
- (BOOL)shouldAutorotate;
#end
#implementation UITabBarController (rotation)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if ([self.selectedViewController isKindOfClass:[UINavigationController class]])
{
UINavigationController *navController = (UINavigationController *) self.selectedViewController;
if ([[navController visibleViewController] isKindOfClass:[CLASS_NAME_FOR_ROTATION class]])
return YES;
}
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}
- (NSUInteger)supportedInterfaceOrientations
{
if ([self.selectedViewController isKindOfClass:[UINavigationController class]])
{
UINavigationController *navController = (UINavigationController *) self.selectedViewController;
if ([[navController visibleViewController] isKindOfClass:[CLASS_NAME_FOR_ROTATION class]])
return UIInterfaceOrientationMaskAll;
}
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL)shouldAutorotate
{
if ([self.selectedViewController isKindOfClass:[UINavigationController class]])
{
UINavigationController *navController = (UINavigationController *) self.selectedViewController;
if ([[navController visibleViewController] isKindOfClass:[CLASS_NAME_FOR_ROTATION class]])
return YES;
}
return NO;
}
#end
Use this code in the parent View Controller of the class (i.e. the just previous class on the stack of navigation controller) that is to be rotated.
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
In your appDelegate add the this code
#property(nonatomic,assign)BOOL shouldRotate;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
shouldRotate=NO;
}
-(void)shouldAutoRotate:(BOOL)rotate
{
self.shouldRotate=rotate;
}
And in your rootview controller add this code
#import "AppDelegate.h"
#define myAppDelegate (AppDelegate *)[[UIApplication sharedApplication] delegate]
- (NSUInteger)supportedInterfaceOrientations
{
if(![myAppDelegate shouldRotate])
return UIInterfaceOrientationMaskPortrait;
else
return UIInterfaceOrientationMaskAllButUpsideDown;
}
After that add this code in viewcontroller.m which is you want to rotate
- (void)viewDidLoad
{
[super viewDidLoad];
[myAppDelegate shouldAutoRotate:YES];
}
-(void)viewWillDisappear:(BOOL)animated
{
[myAppDelegate shouldAutoRotate:NO];
}
I have done this for one of the my projects( IOS 7).It works for me perfectly.
You can create a category to override the methods in navigationController to support all classes.
#implementation UINavigationController (Rotation_IOS6)
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
#end
If you want to restrict the rotation in different controllers then override the supportedInterfaceOrientations and shouldAutorote in respective viewcontrollers changing the return value as required.
-(NSUInteger)supportedInterfaceOrientations
{
return self.topViewController.supportedInterfaceOrientations;
}

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'm a little bit confused.
I want my app to rotate in exactly one of my 5 Viewcontrollers.
I created a Category for UINavigationcontroller implementing the necessary methods for rotating in ios 6.
#import "UINavigationController+IOS6Rotation.h"
#implementation UINavigationController (IOS6Rotation)
-(BOOL)shouldAutorotate
{
return [self.topViewController shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
if (INTERFACE_IS_PAD) {
return UIInterfaceOrientationLandscapeLeft;
}
else{
return UIInterfaceOrientationPortrait;
}
}
#end
I also have implemented these methods in all my ViewControllers which should not rotate.
- (BOOL)shouldAutorotate {
return NO;
}
- (BOOL)supportedInterfaceOrientations {
if (INTERFACE_IS_PAD) {
return UIInterfaceOrientationMaskLandscape;
}
else{
return UIInterfaceOrientationMaskPortrait;
}
}
The one who should rotate returns YES in shouldAutorotate
On Startup, i use an extra Viewcontroller to show a Splashscreen. This SplashScreen is displayed as RootViewController like this.
vc_splash = [[SplashScreenViewController alloc] initWithNibName:#"SplashScreenViewController" bundle:[NSBundle mainBundle]];
[self.window setRootViewController:vc_splash];
DefaultSHKConfigurator *configurator = [[MySHKConfigurator alloc] init];
[SHKConfiguration sharedInstanceWithConfigurator:configurator];
[self.window makeKeyAndVisible];
When I'm finished loading my database, the splashscreen is exchanged for the mainscreen.
self.viewController = [[MainViewController alloc] initWithNibName:#"MainViewController_iPhone" bundle:nil];
UINavigationController *navControl = [[UINavigationController alloc] initWithRootViewController: self.viewController];
[self.window setRootViewController: navControl];
Problem now is, that only my Splashscreen calls shouldAutorotate, but the other screens don't.
Can someone tell me if i have missed some essentials here?
I thought i had done all necessary stuff to get that bl****y autorotation to work correctly in ios 6...
Thx in advance,
Maverick1st
**update**
If you want your iPad to start in Landscape, be sure to return YES in your shouldAutoRotate,
this is working for me add supportedInterfaceOrientationsForWindow
method in application delegate:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;
[navigationController shouldAutorotate];
[navigationController preferredInterfaceOrientationForPresentation];
return UIInterfaceOrientationMaskAll;
}
Also add this in application delegate:
#implementation UINavigationController (Rotation_IOS6)
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
#end
I want to know device orientation when the view will appear.
Previously it was possible using the shouldAutorotateToInterfaceOrientation method but in IOS 6 it is deprecated.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (interfaceOrientation==UIInterfaceOrientationPortrait ||interfaceOrientation==UIInterfaceOrientationPortraitUpsideDown ) {
DashBtn.hidden=NO;
}
else
{
DashBtn.hidden=YES;
if (self.popoverControllerMain) {
[self.popoverControllerMain dismissPopoverAnimated:YES];
}
}
return YES;
}
I checked all the post
i.e making rootviewcontroller and
- (BOOL)shouldAutorotate {
return NO;
}// this method is not called
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
Create category of UINavigationController and add below code #implementation UINavigationController (Rotation_IOS6)
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
#end
Try using
-(void)willAnimateRotationToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
instead of
(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
refer http://developer.apple.com/library/ios/#documentation/uikit/reference/UIViewController_Class/Reference/Reference.html for details.
The best option to know the device orientation is
[[UIApplication sharedApplication] statusBarOrientation]
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 QuickLook (QLPreviewController) almost working how I want it, but because of the images characteristics I don't want it to rotate into portrait orientation.I have it configured in the "shouldAutoRotateToInterfaceOrientation" method to only return yes for landscape rotations (see code below for details) but it is still rotating to portrait.
Note: The shouldAutoRotateToInterfaceOrientation is a direct copy that is used in all of my view controllers for this project and it is working in the other view controllers.
//
// documentViewer.m
//
#import "DocumentViewer.h"
#implementation DocumentViewer
#synthesize documents;
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft)
return YES;
else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight)
return YES;
else
return NO;
}
- (void)viewDidLoad {
[super viewDidLoad];
}
//-(void)viewWillAppear:(BOOL)animated {
//
// self.userInteractionEnabled = YES;
//}
//Nessary for Enabling User Interaction
- (BOOL)canBecomeFirstResponder {
return YES;
}
-(void) createList:(NSString *) document {
documents = [[NSArray arrayWithObjects:document, nil] retain];
}
-(NSInteger) numberOfPreviewItemsInPreviewController: (QLPreviewController *) controller {
return [documents count];
}
- (id <QLPreviewItem>) previewController: (QLPreviewController *) controller previewItemAtIndex: (NSInteger) index {
return [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:[documents objectAtIndex:index] ofType:nil]];
}
#end
In AppDelegate.m replace
return UIInterfaceOrientationMaskAll;
with
return UIInterfaceOrientationMaskLandscape;
just like this:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
return UIInterfaceOrientationMaskLandscape;
}
According to the ViewController Programming Guide for iOS, the autorotation is roughly controlled by the ViewController that was most recently made visible.
In your case that's probably the QLPreviewController itself, not your DocumentViewer. (And you say that the latter's shouldAutorotateToInterfaceOrientation: isn't called, which is consistent with this hypothesis).
So the autorotation is controlled by the shouldAutorotateToInterfaceOrientation: method of QLPreviewController, which in a little experiment of mine seems to allow everything but upside-down orientation.
So what you can do is define a subclass of QLPreviewController that only overrides shouldAutorotateToInterfaceOrientation: the way you did in DocumentViewer and use this subclass instead of the original QLPreviewController.
LandscapeOnlyQLPreviewController.h:
#import <QuickLook/QuickLook.h>
#interface LandscapeOnlyQLPreviewController : QLPreviewController {
}
#end
LandscapeOnlyQLPreviewController.m:
#import "LandscapeOnlyQLPreviewController.h"
#implementation LandscapeOnlyQLPreviewController
- (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation) interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
#end
I never did find a good answer, so I ended up just using a UIWebView.
But I'm still looking.
Try this:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
