I have this setup to support only landscape orientation in most of my viewcontrollers
My app delegate has this piece of code:
-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
NSUInteger orientations = UIInterfaceOrientationMaskLandscape;
if (self.window.rootViewController) {
UIViewController * pressented = [[((UINavigationController *)self.window.rootViewController) viewControllers] lastObject];
orientations =[pressented supportedInterfaceOrientations];
}
return orientations;
}
And in most viewcontrollers this:
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
My problem comes when I push THIS controller (the one I would like to rotate):
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskALL;
}
It rotates perfectly BUT when I pop the viewcontroller (tap the back button of the navigation bar) with the orientation in portrait, the presenting viewcontroller also sets it's orientation to Portrait.
How can I make the presenting viewcontroller stays locked on landscape, or force the problematic controller to rotate back to landscape before popping.
Add this to your portrait view controller:
-(void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];
UIViewController* dummyController = [[UIViewController alloc] init];
[self presentViewController:dummyController animated:NO completion:^{
[self dismissViewControllerAnimated:NO completion:nil];
}];
}
I know it's a hack, but it works. Anyone knows a better solution?

In my app we need only one view controller would be in all orientation mode other view controllers will be portrait mode only.
I am using below code and it's working perfectly but when coming back to pervious view controller it's not rotating in portrait mode when I am coming from Landscape mode.
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
// Get topmost/visible view controller
UIViewController *currentViewController = [self topViewController];
// Check whether it implements a dummy methods called canRotate
if ([currentViewController respondsToSelector:#selector(canRotate)]) {
// Unlock landscape view orientations for this view controller
return UIInterfaceOrientationMaskAllButUpsideDown;
}
// Only allow portrait (standard behaviour)
return UIInterfaceOrientationMaskPortrait;
}
- (UIViewController*)topViewController {
return [self topViewControllerWithRootViewController:[UIApplication sharedApplication].keyWindow.rootViewController];
}
- (UIViewController*)topViewControllerWithRootViewController:(UIViewController*)rootViewController {
if ([rootViewController isKindOfClass:[UITabBarController class]]) {
UITabBarController* tabBarController = (UITabBarController*)rootViewController;
return [self topViewControllerWithRootViewController:tabBarController.selectedViewController];
} else if ([rootViewController isKindOfClass:[UINavigationController class]]) {
UINavigationController* navigationController = (UINavigationController*)rootViewController;
return [self topViewControllerWithRootViewController:navigationController.visibleViewController];
} else if (rootViewController.presentedViewController) {
UIViewController* presentedViewController = rootViewController.presentedViewController;
return [self topViewControllerWithRootViewController:presentedViewController];
} else {
return rootViewController;
}
}
I've been working against the same issue. The orientation can be forced back to its normal configuration by adding an adjustment in viewWillAppear of the controller you are going back to:
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
[[UIDevice currentDevice] setValue:value forKey:#"orientation"];
}
I am using MoviePlayer controller to play a video in my iOS app. I am using orientation notification like this
if(deviceOrientation ==UIDeviceOrientationLandscapeLeft)
{
NSLog(#"Replay is in Landscape");
self.fullScreenFlag = YES;
[self.moviePlayer setFullscreen:YES animated:NO];
}
This makes my video screen to play in full screen when user turns the phone to landscape orientation. But when I press done button on moviePlayer control I go into following method
- (void)movieWillExitFullscreen:(NSNotification*)notification
{
UIDeviceOrientation deviceOrientation = [UIDevice currentDevice].orientation;
if(deviceOrientation ==UIDeviceOrientationLandscapeLeft) {
NSLog(#"Pressed Done in Landscape");
//Problem: Here I want to force my VideoViewController to rotate back to portrait Mode
}
}
Not sure how can I make the VC to go back to portrait as soon as user pressed done button or video stops playing. I am aware to the moviePlayerNotificationMethods but what should I call in those method for orientation is not clear.
I solved this issue by having a separate view controller for the video playback.
So, you would have two view controllers
SomeViewController
MoviePlayerViewController
In your SomeViewController, when you want to play the movie:
MoviePlayerViewController *vc = [[MoviePlayerViewController alloc] initWithNibName:#"MoviePlayerViewController" bundle:nil];
[vc setPathToMovie:path];
[self.navigationController pushViewController:vc animated:YES];
[vc release];
And then in your MoviePlayerViewController
- (void) moviePlayBackDidFinish:(NSNotification*)notification
{
[[self navigationController] popViewControllerAnimated:YES];
}
You can then lock down your SomeViewController to portrait, and if the user is in landscape when watching the video, they will return to portrait when popping back to SomeViewController.
I never found a solution using the deviceOrientation method and a modal MPMoviePlayerController. There may be one though!
I solved this by doing this in "moviePlayBackDidFinish"
UIViewController* forcePortrait = [[UIViewController alloc] init];
[self presentViewController:forcePortrait animated:NO completion:^{
[forcePortrait dismissViewControllerAnimated:NO completion:nil];
}];
It's not beautiful but it works like a charm :-)
Depending upon whether you using MPMoviePlayerController within a ViewController or as a separate ViewController the answer is as follows :-
Firstly :- This link will explain you how to restrict some views to portrait and allow others to rotate?
In that link you will see that, in the NavigationViewController you have made, following changes:-
-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
What it does is, it give the child to make their own decision if they want to auto-rotate or not.
Next the ViewController containing your MoviePlayer should do this :-
-(BOOL)shouldAutorotate
{
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
Once you have done this, it gives the power of AutoRotation to your ViewController.
Now here's the tricky part, see I assume that you might have restricted your ViewController to Portrait, and since movie player allows you go fullscreen and in fullscreen when you rotate your screen it will turn to landscape, and now if you press done button it won't turn to portrait rather it will exit the fullscreen in landscape itself. In this case what you should do is, in your:-
- (BOOL)shouldAutorotate
{
UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIInterfaceOrientationLandscapeRight || orientation == UIInterfaceOrientationLandscapeLeft) {
if ([[[self.navigationViewController.viewControllers] lastObject] class] == [MoviePlayerViewController class] ) {
return YES;
}
return NO;
}
return NO;
}
So, what it does is, you should auto-rotate only when the orientation is landscape and not when its portrait.
So far so good, next comes the MoviePlayer, considering that you have already played the Video and your only interest is when we click "Done" button it should auto-rotate to portrait.
Register for a notification to your MoviePlayer
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(moviePlayerWillExitFullScreen:) name:MPMoviePlayerWillExitFullscreenNotification object:_moviePlayer];
Then in the selector:
- (void) moviePlayerWillExitFullScreen:(NSNotification*)notification{
NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
[[UIDevice currentDevice] setValue:value forKey:#"orientation"];
[[NSNotificationCenter defaultCenter] removeObserver:self name:MPMoviePlayerWillExitFullscreenNotification object:_moviePlayer];
}
Tada! the magic is done! try out let me know ;-)
I am working on iOS 6 application, I have handled the UIview rotation using following methods...
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (BOOL) shouldAutorotate {
return YES;
}
Everything is working fine, problem is initial view loading is decided based on device orientation, for e.g.: if I keep my device in landscape mode even though I have returned as forcibly portrait in supportedInterfaceOrientations view is showing in landscape only, once device is rotated to portrait after that it is not going to landscape mode, all working fine. Is it possible to load a View at certain mode irrespective of the device orientation?
I have googled and nothing worked.
NOTE: I am using navigation controller. And I have added category for UINavigationController.
// Custom categoy to handle orientation in IOS6
#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
thanks
Use this method:
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationMaskPortrait;
}
Add this method along with category for UINavigationController in appDelegate.
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
UINavigationController *navigationController = (UINavigationController *)self.window.rootViewController;
//check for which controller u need these methods
if([navigationController.visibleViewController isKindOfClass:[yourViewController class]]) //provide specific view controller where u want protrait
{
[navigationController shouldAutorotate];
[navigationController supportedInterfaceOrientations];
[navigationController preferredInterfaceOrientationForPresentation];
}
return UIInterfaceOrientationMaskAll;
}
Note : remove from all viewController if u have added category for UINavigationController. It should be only in appDelegate.
I want to rotate ONLY one of my views within my app to either landscape left or landscape right. All my other views are in portrait mode and I have set my app to support only portrait mode. With orientation being changed in iOS 6, I am not sure how to do this. I have tried the following posted below. Can anyone tell me what I am doing wrong? Thanks!
-(BOOL)shouldAutorotate {
return YES;
}
-(NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
}
I have also tried:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(didRotate:)
name:UIDeviceOrientationDidChangeNotification
object:nil];
return YES;//UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
}
-(void)didRotate:(NSNotification *)notification {
UIDeviceOrientation orientation = [[notification object] orientation];
if (orientation == UIDeviceOrientationLandscapeLeft) {
[theImage setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
} else if (orientation == UIDeviceOrientationLandscapeRight) {
[theImage setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
} else if (orientation == UIDeviceOrientationPortraitUpsideDown) {
[theImage setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)];
} else if (orientation == UIDeviceOrientationPortrait) {
[theImage setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
[self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)];
}
}
This worked for me How to force a UIViewController to Portrait orientation in iOS 6
Create a new category from UINavigationController overriding the rotating methods:
-(BOOL)shouldAutorotate
{
return [self.topViewController shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [self.topViewController preferredInterfaceOrientationForPresentation];
}
#end
There are changes in iOS 6 regarding handling view rotations. Only orientations defined in apps Info.plist are supported. Even if you are returning other ones.
Try to select all orientations as supported in your project.
Handling View Rotations
In iOS 6, your app supports the interface orientations defined in your app’s Info.plist file. A view controller can override the supportedInterfaceOrientations method to limit the list of supported orientations. Generally, the system calls this method only on the root view controller of the window or a view controller presented to fill the entire screen; child view controllers use the portion of the window provided for them by their parent view controller and no longer participate in directly in decisions about what rotations are supported. The intersection of the app’s orientation mask and the view controller’s orientation mask is used to determine which orientations a view controller can be rotated into.
You can override the preferredInterfaceOrientationForPresentation for a view controller that is intended to be presented full screen in a specific orientation.
In iOS 5 and earlier, the UIViewController class displays views in portrait mode only. To support additional orientations, you must override the shouldAutorotateToInterfaceOrientation: method and return YES for any orientations your subclass supports. If the autoresizing properties of your views are configured correctly, that may be all you have to do. However, the UIViewController class provides additional hooks for you to implement additional behaviors as needed. Generally, if your view controller is intended to be used as a child view controller, it should support all interface orientations.
When a rotation occurs for a visible view controller, the willRotateToInterfaceOrientation:duration:, willAnimateRotationToInterfaceOrientation:duration:, and didRotateFromInterfaceOrientation: methods are called during the rotation. The viewWillLayoutSubviews method is also called after the view is resized and positioned by its parent. If a view controller is not visible when an orientation change occurs, then the rotation methods are never called. However, the viewWillLayoutSubviews method is called when the view becomes visible. Your implementation of this method can call the statusBarOrientation method to determine the device orientation.
(C) Apple Docs: UIViewController
Follow the below steps
Create subclass of UINavigationController overriding the rotating methods.
In AppDelegate, create a BOOL islandscape property.
When a view is pushed/poped/present/dismiss, adjust this BOOL value.
Sample Project
I created a sample project for this which is working perfectly. Download and integrate in your project: https://www.dropbox.com/s/nl1wicbx52veq41/RotationDmeo.zip?dl=0
I have a:
TabbarController -> NavigationController -> ViewController -> ViewController
I Subclassed UITabBarController and add....
-(NSUInteger)supportedInterfaceOrientations{
if (self.selectedIndex >= 0 && self.selectedIndex < 100) {
for (id vC in [[self.viewControllers objectAtIndex:(unsigned long)self.selectedIndex] viewControllers]) {
if ([vC isKindOfClass:[CLASS_WHICH_SHOULD_ALLOW class]]) {
return UIInterfaceOrientationMaskPortrait + UIInterfaceOrientationMaskLandscape;
}
}
}
return UIInterfaceOrientationMaskPortrait;
}
I have been searching for the solution for hours!
So after implementing the needed methods everywhere. shouldAutorotate doesn't need to be set to YES because it is already set as default:
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationPortrait;
}
When it is time to show the UIViewController which needs the orientation different than the other views, I created a UIStoryboardSegue with this implementation inside:
#import "Showing.h"
#implementation Showing
- (void)perform{
NSLog(#"Showing");
UIViewController *sourceVC = self.sourceViewController;
UIViewController *presentingVC = self.destinationViewController;
[sourceVC.navigationController presentViewController:presentingVC
animated:YES
completion:nil];
}
#end
Inside the UIStoryboard I connected the views with this segue (showing):
It is just important, you are using
presentViewController:animated:completion:
AND NOT
pushViewController:animated:
otherwise the orientation won't be determined again.
I had been trying things like
[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationPortrait];
OR this one inside the UIViewController where the orientation should change, and I also tryied to call it inside my custom UIStoryboardSegues before presentingViewController and dismissViewController:
[UIViewController attemptRotationToDeviceOrientation];
OR
NSNumber *numPortrait = [NSNumber numberWithInt:UIInterfaceOrientationPortrait];
[[UIDevice currentDevice] setValue:numPortrait forKey:#"orientation"];
But no one of them worked. Of course the last example shouldn't be an option, because if apple will change anything of their api this could cause problems inside your app.
I also tried to use the AppDelegate method and always determine the orientation inside this method after looking for the correct UIInterfaceOrientation of the actual visibleViewController but then it sometimes happened to crash when switching from one to another orientation. So I'm still wondering why its made so complicated and there seems also not to be any documentation where it is explained correctly.
Even following this part didn't help me.
UIViewController+OrientationPermissions.h
#interface UIViewController (OrientationPermissions)
+ (void)setSupportedOrientations:(UIInterfaceOrientationMask)supportedOrientations;
+ (UIInterfaceOrientationMask)supportedOrientations;
#end
UIViewController+OrientationPermissions.m
#implementation UIViewController (OrientationPermissions)
static UIInterfaceOrientationMask _supportedOrientations;
+ (void)setSupportedOrientations: (UIInterfaceOrientationMask)supportedOrientations {
_supportedOrientations = supportedOrientations;
}
+ (UIInterfaceOrientationMask)supportedOrientations {
return _supportedOrientations;
}
#end
In your UIApplication delegate
- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
return [UIViewController supportedOrientations];
}
Then on a desired view controller do something like
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[UIViewController setSupportedOrientations:UIInterfaceOrientationMaskAll];
}
Don't forget to reset mask before leaving this view controller
Note, if you are using UINavigationController or UITabBarController, see https://stackoverflow.com/a/28220616/821994 how to bypass that
Defiantly work Please try.
I solve after 2 days
//AppDelegate.m - this method is not available pre-iOS6 unfortunately
- (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;
}
//MyViewController.m - return whatever orientations you want to support for each UIViewController
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
I have a MainViewController which has a button which pushes a new view (InfoViewController), via flip horizontailly. like so:
controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:controller animated:YES];
The MainView Controller supports Portrait and PortraitUpsideDown. Like so:
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskPortrait |
UIInterfaceOrientationMaskPortraitUpsideDown);
}
In my InfoViewController it also states the above code. In my AppDelegate it has this in the LaunchOptions:
[self.window setRootViewController:self.mainViewController];
In my app.plist file it supports all orientations. This is because other views need to support landscape as well. So On my MainViewController and InfoViewController I need only Portrait and PortraitUpsideDown. But on another view I need all orintations.
My MainViewController works fine, but my InfoViewController is working for all orientations.
I am having extreme diffulty trying to get this to work in iOS6. I have researched other posts and tried the assistance other people have provided, but had no luck whatsoever. Please can someone help me acheive this thank you. And I'm a Objective-C newbie :p
Don´t support all orientations in your app plist file, only those that your root view controller supports.
Autorotation is changing in iOS 6. In iOS 6, the shouldAutorotateToInterfaceOrientation: method of UIViewController is deprecated. In its place, you should use the supportedInterfaceOrientationsForWindow: and shouldAutorotate methods:
- (BOOL)shouldAutorotate {
return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
Modal ViewControllers no longer get rotation calls in iOS 6:
The willRotateToInterfaceOrientation:duration:,
willAnimateRotationToInterfaceOrientation:duration:, and
didRotateFromInterfaceOrientation: methods are no longer called on any view controller that makes a full-screen presentation over
itself—for example those that are called with: presentViewController:animated:completion:.
You can let the view controller that presents your modal view controller inform it of rotation.
Also, now you use: presentViewController:animated:completion: to present the view controller. presentModalViewController:animated: is deprecated which you use in the code.
I have solved similar problems, while using tab bar controller.
Subclass UITabBarController. Implement these methods:
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskAll;
}
- (BOOL)shouldAutorotate
{
NSLog(#"Orientation:%d", [[UIDevice currentDevice] orientation]);
for (UIViewController *viewController in self.viewControllers) {
[viewController shouldAutorotate];
}
return YES;
}
If you want to handle rotations in controllers inside tabbarcontroller, in each of the controllers in the tab bar controller implement those methods too and write code to handle orientation change. If you don't want to handle it, then you don't need to implement those methods. TabBarControllers methods will always run when orientation changes. Even twice for unknown reason.
Yes, and don't forget to delete all shouldAutorotate methods. I moved to the new orientation model completely. If you want to make them remain, probably, it will be harder.
Make a category by subclassing UINavigationController and implement following methodes
in .h file
-(BOOL)shouldAutorotate;
-(NSUInteger)supportedInterfaceOrientations;
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation;
in .m file
-(BOOL)shouldAutorotate
{
return [self.topViewController shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [self.topViewController preferredInterfaceOrientationForPresentation];
}
and implement following methodes in the view controller class ,class u want to enable rotation
-(NSUInteger)supportedInterfaceOrientations
{
return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskPortraitUpsideDown);
}
- (BOOL)shouldAutorotate
{
return YES;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeLeft;
}
add this code on Subclass UITabBarController .m
#implementation UINavigationController (rotation)
//temp hack for iOS6, this allows passing supportedInterfaceOrientations to child viewcontrollers.
- (NSUInteger)supportedInterfaceOrientations {
return [self.topViewController supportedInterfaceOrientations];
}
#end
#implementation NameClassUITabBar
- (void)viewDidLoad {
[super viewDidLoad];
}
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape;
}
#end
