How to force a UIViewController to Portrait orientation in iOS 6

Question

As the ShouldAutorotateToInterfaceOrientation is deprecated in iOS 6 and I used that to force a particular view to portrait only  what is the correct way to do this in iOS 6   This is only for one area of my app  all other views can rotate

User · Answer

The best way for iOS6 specifically is noted in "iOS6 By Tutorials" by the Ray Wenderlich team - http://www.raywenderlich.com/ and is better than subclassing UINavigationController for most cases.

I'm using iOS6 with a storyboard that includes a UINavigationController set as the initial view controller.

//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;
}

Not to be dull here  but would you be so kind to share your subclass  Thank you   edit  well  I finally did it  the subclass was dead simple to do  I just had to declare the navigationController in the AppDelegate as UINavigationControllerSubclass instead of the default UINavigationController  then modified your subclass with   -  BOOL shouldAutorotate       return  shouldRotate      so I can set any view I want to rotate or not by calling at viewDidLoad   navController    UINavigationController   self navigationController    navController setShouldRotate   YES   NO    Hope this tweak will help others as well  thanks for your tip   Tip  Make use of  -  NSUInteger supportedInterfaceOrientations   in your view controllers  so you don t end up by having a portrait desired view in landscape or vice versa

The answers using subclasses or categories to allow VCs within UINavigationController and UITabBarController classes work well  Launching a portrait-only modal from a landscape tab bar controller failed  If you need to do this  then use the trick of displaying and hiding a non-animated modal view  but do it in the viewDidAppear method  It didn t work for me in viewDidLoad or viewWillAppear   Apart from that  the solutions above work fine

If you want all of our navigation controllers to respect the top view controller you can use a category so you don t have to go through and change a bunch of class names    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   As a few of the comments point to  this is a quick fix to the problem  A better solution is subclass UINavigationController and put these methods there  A subclass also helps for supporting 6 and 7

For Monotouch you could do it this way   public override UIInterfaceOrientationMask GetSupportedInterfaceOrientations             return UIInterfaceOrientationMask LandscapeRight     public override UIInterfaceOrientation PreferredInterfaceOrientationForPresentation             return UIInterfaceOrientation LandscapeRight

I have a very good approach mixing https   stackoverflow com a 13982508 2516436 and https   stackoverflow com a 17578272 2516436  - NSUInteger application  UIApplication   application supportedInterfaceOrientationsForWindow  UIWindow   window      NSUInteger orientations   UIInterfaceOrientationMaskAllButUpsideDown        if self window rootViewController           UIViewController  presentedViewController    self topViewControllerWithRootViewController self window rootViewController           orientations    presentedViewController supportedInterfaceOrientations              return orientations     -  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            and return whatever orientations you want to support for each UIViewController  -  NSUInteger supportedInterfaceOrientations      return UIInterfaceOrientationMaskPortrait

Just go to project plist then add Supported interface orientation and then add only Portrait  bottom home button  and Portrait  top home button     You can add or remove there orientation as per your project requirement     Thanks

So I ran into the same problem when displaying portrait only modal views  Normally  I d create a UINavigationController  set the viewController as the rootViewController  then display the UINavigationController as a modal view  But with iOS 6  the viewController will now ask the navigationController for its supported interface orientations  which  by default  is now all for iPad and everything but upside down for iPhone     Solution  I had to subclass UINavigationController and override the autorotation methods  Kind of lame    -  BOOL shouldAutorotate       return NO     -  NSUInteger supportedInterfaceOrientations       return UIInterfaceOrientationMaskPortrait       pre-iOS 6 support  -  BOOL shouldAutorotateToInterfaceOrientation  UIInterfaceOrientation toInterfaceOrientation       return  toInterfaceOrientation    UIInterfaceOrientationPortrait

1  Check your project settings and info plist and make sure that only the orientations you want are selected   2  add the following methods to your topmost view controller navigation controller tabbar controller   -  NSUInteger  supportedInterfaceOrientations       return UIInterfaceOrientationMaskPortrait       3  add the following methods to your app delegate  -  NSUInteger  supportedInterfaceOrientations       return UIInterfaceOrientationMaskPortrait      -  NSUInteger application  UIApplication   application supportedInterfaceOrientationsForWindow  UIWindow   window       return UIInterfaceOrientationMaskPortrait

User · Answer

I did not test it myself  but the documentation states that you can now override those methods  supportedInterfaceOrientations and preferredInterfaceOrientationForPresentation   You can probably achieve what you want y setting only the orientation that you want in those methods

I have a relatively complex universal app using UISplitViewController and UISegmentedController  and have a few views that must be presented in Landscape using presentViewController  Using the methods suggested above  I was able to get iPhone ios 5  amp  6 to work acceptably  but for some reason the iPad simply refused to present as Landscape  Finally  I found a simple solution  implemented after hours of reading and trial and error  that works for both devices and ios 5  amp  6   Step 1  On the controller  specify the required orientation  more or less as noted above   -  BOOL shouldAutorotateToInterfaceOrientation  UIInterfaceOrientation interfaceOrientation       return  interfaceOrientation    UIInterfaceOrientationLandscapeRight      - BOOL shouldAutorotate       return YES     - NSUInteger supportedInterfaceOrientations       NSInteger mask   UIInterfaceOrientationMaskLandscape      return mask       Step 2  Create a simple UINavigationController subclass and implement the following methods  - BOOL shouldAutorotate           return YES    -  NSUInteger supportedInterfaceOrientations           return UIInterfaceOrientationMaskLandscape      Step 3  Present your viewController  vc     MyViewController alloc init   MyLandscapeNavigationController  myNavigationController     MyLandscapeNavigationController alloc  initWithRootViewController vc    self myNavigationController animated YES completion nil     Hope this is helpful to someone

This answer relates to the questions asked in the comments of the OP s post   To force a view to appear in a given oriention put the following in viewWillAppear       UIApplication  application    UIApplication sharedApplication   if  application statusBarOrientation    UIInterfaceOrientationPortrait        UIViewController  c     UIViewController alloc init        self presentModalViewController c animated NO        self dismissModalViewControllerAnimated NO       It s a bit of a hack  but this forces the UIViewController to be presented in portrait even if the previous controller was landscape  UPDATE for iOS7  The methods above are now deprecated  so for iOS 7 use the following   UIApplication  application    UIApplication sharedApplication   if  application statusBarOrientation    UIInterfaceOrientationPortrait         UIViewController  c     UIViewController alloc init         c view setBackgroundColor  UIColor redColor          self navigationController presentViewController c animated NO completion                 self navigationController dismissViewControllerAnimated YES completion                                 Interestingly  at the time of writing  either the present or dismiss  must be animated  If neither are  then you will get a white screen  No idea why this makes it work  but it does  The visual effect is different depending on which is animated

Put this in the  m file of each ViewController you don t want to rotate   -  NSUInteger supportedInterfaceOrientations         return UIInterfaceOrientationMaskPortrait   UIInterfaceOrientationMaskLandscapeLeft      return UIInterfaceOrientationMaskPortrait      See here for more information

I disagree from  aprato answer  because the UIViewController rotation methods are declared in categories themselves  thus resulting in undefined behavior if you override then in another category  Its safer to override them in a UINavigationController  or UITabBarController  subclass  Also  this does not cover the scenario where you push   present   pop from a Landscape view into a portrait only VC or vice-versa  To solve this tough issue  never addressed by Apple   you should   In iOS  lt   4 and iOS    6   UIViewController  vc     UIViewController alloc init    self presentModalViewController vc animated NO    self dismissModalViewControllerAnimated NO    vc release     In iOS 5   UIWindow  window     UIApplication sharedApplication  keyWindow   UIView  view    window subviews objectAtIndex 0    view removeFromSuperview    window addSubview view     These will REALLY force UIKit to re-evaluate all your shouldAutorotate   supportedInterfaceOrientations  etc
