How to force view controller orientation in iOS 8

Question

Before iOS 8  we used below code in conjunction with supportedInterfaceOrientations and shouldAutoRotate delegate methods to force app orientation to any particular orientation  I used below code snippet to programmatically rotate the app to desired orientation  Firstly  I am changing the status bar orientation  And then just presenting and immediately dismissing a modal view rotates the view to desired orientation      UIApplication sharedApplication  setStatusBarOrientation UIInterfaceOrientationLandscapeRight animated YES   UIViewController  c     UIViewController alloc init    self presentViewController vc animated NO completion nil    self dismissViewControllerAnimated NO completion nil     But this is failing in iOS 8  Also  I have seen some answers in stack overflow where people suggested that we should always avoid this approach from iOS 8 onwards    To be more specific  my application is a universal type of application  There are three controllers in total    First View controller- It should support all orientations in iPad and    only portrait  home button down  in iPhone  Second View controller- It should support only landscape right in all conditions Third View controller- It should support only landscape right in all conditions   We are using navigation controller for page navigation  From the first view controller  on a button click action  we are pushing the second one on stack  So  when the second view controller arrives  irrespective of device orientation  the app should lock in landscape right only   Below is my shouldAutorotate and supportedInterfaceOrientations methods in second and third view controller   - NSUInteger supportedInterfaceOrientations      return UIInterfaceOrientationMaskLandscapeRight     - BOOL shouldAutorotate       return NO      Is there any solution for this or any better way of locking a view controller in particular orientation for iOS 8  Please help

There still seems to be some debate about how best to accomplish this task, so I thought I'd share my (working) approach. Add the following code in your UIViewController implementation:

- (void) viewWillAppear:(BOOL)animated
{
    [UIViewController attemptRotationToDeviceOrientation];
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
{
    return (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

-(BOOL)shouldAutorotate
{
    return NO;
}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeLeft;
}

For this example, you will also need to set your allowed device orientations to 'Landscape Left' in your project settings (or directly in info.plist). Just change the specific orientation you want to force if you want something other than LandscapeLeft.

The key for me was the attemptRotationToDeviceOrientation call in viewWillAppear - without that the view would not properly rotate without physically rotating the device.

On Xcode 8 the methods are converted to properties  so the following works with Swift   override public var supportedInterfaceOrientations  UIInterfaceOrientationMask       return UIInterfaceOrientationMask portrait    override public var preferredInterfaceOrientationForPresentation  UIInterfaceOrientation       return UIInterfaceOrientation portrait    override public var shouldAutorotate  Bool       return true

The combination of Sids and Koreys answers worked for me     Extending the Navigation Controller   extension UINavigationController       public override func shouldAutorotate   - gt  Bool           return visibleViewController shouldAutorotate             Then disabling rotation on the single View   class ViewController  UIViewController       override func shouldAutorotate   - gt  Bool           return false           And rotating to the appropriate orientation before the segue  override func prepareForSegue segue  UIStoryboardSegue  sender  AnyObject         if  segue identifier     SomeSegue                 let value   UIInterfaceOrientation Portrait rawValue          UIDevice currentDevice   setValue value  forKey   orientation

According to solution showed by  sid-sha you have to put everything in the viewDidAppear  method  otherwise you will not get the didRotateFromInterfaceOrientation  fired  so something like   -  void viewDidAppear  BOOL animated        super viewDidAppear animated       UIInterfaceOrientation interfaceOrientation     UIApplication sharedApplication  statusBarOrientation       if  interfaceOrientation    UIInterfaceOrientationLandscapeLeft            interfaceOrientation    UIInterfaceOrientationLandscapeRight            NSNumber  value    NSNumber numberWithInt interfaceOrientation             UIDevice currentDevice  setValue value forKey   orientation

I tried a few solutions in here and the important thing to understand is that it s the root view controller that will determine if it will rotate or not   I created the following objective-c project github com GabLeRoux RotationLockInTabbedViewChild with a working example of a TabbedViewController where one child view is allowed rotating and the other child view is locked in portrait   It s not perfect but it works and the same idea should work for other kind of root views such as NavigationViewController

I found that if it s a presented view controller  you can override preferredInterfaceOrientationForPresentation  Swift   override func supportedInterfaceOrientations   - gt  Int     return Int UIInterfaceOrientationMask Landscape rawValue     override func preferredInterfaceOrientationForPresentation   - gt  UIInterfaceOrientation     return UIInterfaceOrientation LandscapeLeft    override func shouldAutorotate   - gt  Bool     return false

I have tried many solutions  but the one that worked for is the following   There is no need to edit the info plist in ios 8 and 9   -  BOOL  shouldAutorotate       return NO        -  UIInterfaceOrientationMask supportedInterfaceOrientations       return  UIInterfaceOrientationPortrait   UIInterfaceOrientationPortraitUpsideDown       Possible orientations from the Apple Documentation      UIInterfaceOrientationUnknown      The orientation of the device cannot be determined       UIInterfaceOrientationPortrait      The device is in portrait mode  with the device held upright and the   home button on the bottom       UIInterfaceOrientationPortraitUpsideDown      The device is in portrait mode but upside down  with the device held   upright and the home button at the top       UIInterfaceOrientationLandscapeLeft      The device is in landscape mode  with the device held upright and the   home button on the left side       UIInterfaceOrientationLandscapeRight      The device is in landscape mode  with the device held upright and the   home button on the right side

This should work from iOS 6 on upwards  but I ve only tested it on iOS 8  Subclass UINavigationController and override the following methods   -  UIInterfaceOrientation preferredInterfaceOrientationForPresentation       return UIInterfaceOrientationLandscapeRight     -  BOOL shouldAutorotate       return NO      Or ask the visible view controller  -  UIInterfaceOrientation preferredInterfaceOrientationForPresentation       return self visibleViewController preferredInterfaceOrientationForPresentation     -  BOOL shouldAutorotate       return self visibleViewController shouldAutorotate      and implement the methods there

My requirements are    lock all views in portrait mode use AVPlayerViewController to play video   When video is playing  if it s a landscape then allow the screen to rotate landscape right and landscape left  If it s a portrait then lock the view in portrait mode only   First  define supportedInterfaceOrientationsForWindow in AppDelegate swift  var portrait   true func application application  UIApplication  supportedInterfaceOrientationsForWindow window  UIWindow   - gt  UIInterfaceOrientationMask       if portrait           return  Portrait       else           return  Landscape           Second  in your main view controller  define following functions  override func supportedInterfaceOrientations   - gt  UIInterfaceOrientationMask       print     function        return  Portrait    override func preferredInterfaceOrientationForPresentation   - gt  UIInterfaceOrientation       return  Portrait    override func shouldAutorotate   - gt  Bool       return false     Then  you need to subclass AVPlayerViewController  class MyPlayerViewController  AVPlayerViewController        var size  CGSize       var supportedOrientationMask  UIInterfaceOrientationMask      var preferredOrientation  UIInterfaceOrientation       override func viewDidLoad             super viewDidLoad            if let size   size               if size width  gt  size height                   self supportedOrientationMask    LandscapeLeft  LandscapeRight                  self preferredOrientation   LandscapeRight               else                   self supportedOrientationMask   Portrait                 self preferredOrientation   Portrait                                 Override these three functions in MyPlayerViewController swift  override func supportedInterfaceOrientations   - gt  UIInterfaceOrientationMask       return self supportedOrientationMask     override func preferredInterfaceOrientationForPresentation   - gt  UIInterfaceOrientation       return self preferredOrientation      Because user might rotate device landscape left or landscape right  we need to set auto rotate to be true  override func shouldAutorotate   - gt  Bool       return true     Finally  create MyPlayerViewController instance in your view controller and set the property size value   let playerViewController   MyPlayerViewController       Get the thumbnail   let thumbnail   MyAlbumFileManager sharedManager   getThumbnailFromMyVideoMedia          let size   thumbnail  size playerViewController size   size   Initiate your player with proper videoUrl  then assign your player to playerViewController  Happy coding

First of all - this is a bad idea  in general  something wrong going with your app architecture  but  sh  t happens  if so  you can try to make something like below   final class OrientationController        static private  set  var allowedOrientation UIInterfaceOrientationMask     all          MARK  - Public      class func lockOrientation   orientationIdiom  UIInterfaceOrientationMask            OrientationController allowedOrientation    orientationIdiom             class func forceLockOrientation   orientation  UIInterfaceOrientation            var mask UIInterfaceOrientationMask              switch orientation               case  unknown                  mask     all              case  portrait                  mask     portrait              case  portraitUpsideDown                  mask     portraitUpsideDown              case  landscapeLeft                  mask     landscapeLeft              case  landscapeRight                  mask     landscapeRight                     OrientationController lockOrientation mask           UIDevice current setValue orientation rawValue  forKey   orientation             Than  in AppDelegate  func application   application  UIApplication  didFinishLaunchingWithOptions launchOptions   UIApplicationLaunchOptionsKey  Any    - gt  Bool          do stuff     OrientationController lockOrientation  portrait      return true       MARK  - Orientation  func application   application  UIApplication  supportedInterfaceOrientationsFor window  UIWindow   - gt  UIInterfaceOrientationMask       return OrientationController allowedOrientation     And whenever you want to change orientation do as   OrientationController forceLockOrientation  landscapeRight    Note  Sometimes  device may not update from such call  so you may need to do as follow  OrientationController forceLockOrientation  portrait  OrientationController forceLockOrientation  landscapeRight    That s all

This way work for me in Swift 2 iOS 8 x   PS  this method dont require to override orientation functions like shouldautorotate on every viewController  just one method on AppDelegate   Check the  requires full screen  in you project general info    So  on AppDelegate swift make a variable   var enableAllOrientation   false   So  put also this func   func application application  UIApplication  supportedInterfaceOrientationsForWindow window  UIWindow   - gt  UIInterfaceOrientationMask           if  enableAllOrientation    true               return UIInterfaceOrientationMask All                   return UIInterfaceOrientationMask Portrait     So  in every class in your project you can set this var in viewWillAppear   override func viewWillAppear animated  Bool            super viewWillAppear animated          let appDelegate   UIApplication sharedApplication   delegate as  AppDelegate         appDelegate enableAllOrientation   true     If you need to make a choices based on the device type you can do this   override func viewWillAppear animated  Bool                super viewWillAppear animated          let appDelegate   UIApplication sharedApplication   delegate as  AppDelegate         switch UIDevice currentDevice   userInterfaceIdiom           case  Phone             It s an iPhone            print   - Only portrait mode to iPhone              appDelegate enableAllOrientation   false         case  Pad             It s an iPad            print   - All orientation mode enabled on iPad              appDelegate enableAllOrientation   true         case  Unspecified             Uh  oh  What could it be             appDelegate enableAllOrientation   false

It looks like even thou here is so much answers no one was sufficient for me  I wanted to force orientation and then on going back go back to device orientation but  UIViewController attemptRotationToDeviceOrientation   just did nt work  What also did complicated whole thing is that I added shouldAutorotate to false based on some answer and could not get desired effects to rotate back correctly in all scenarios   So this is what I did   Before pushing of controller in call in his init constructor this    userOrientation   UIDevice currentDevice orientation   UIDevice currentDevice setValue   UIInterfaceOrientationPortrait  forKey   orientation     self addNotificationCenterObserver  selector rotated                                  name UIDeviceOrientationDidChangeNotification     So I save last device orientation and register for orientation change event  Orientation change event is simple   -  void rotated  NSNotification  notification        userOrientation   UIDevice currentDevice orientation      And on view dissmising I just force back to any orientation I have as userOreintation   -  void onViewDismissing       super onViewDismissing       UIDevice currentDevice setValue    userOrientation  forKey   orientation         UIViewController attemptRotationToDeviceOrientation       And this has to be there too   -  BOOL shouldAutorotate       return true     -  UIInterfaceOrientationMask supportedInterfaceOrientations       return UIInterfaceOrientationMaskPortrait      And also navigation controller has to delegate to shouldAutorotate and  supportedInterfaceOrientations  but that most people already have I believe   PS  Sorry I use some extensions and base classes but names are quite meaningful so concept is understandable  will make even more extensions because it s not too much pretty now

Orientation rotation is a little more complicated if you are inside a UINavigationController or UITabBarController  The problem is that if a view controller is embedded in one of these controllers the navigation or tab bar controller takes precedence and makes the decisions on autorotation and supported orientations   I use the following 2 extensions on UINavigationController and UITabBarController so that view controllers that are embedded in one of these controllers get to make the decisions   Give View Controllers the Power   Swift 2 3  extension UINavigationController       public override func supportedInterfaceOrientations   - gt  Int           return visibleViewController supportedInterfaceOrientations             public override func shouldAutorotate   - gt  Bool           return visibleViewController shouldAutorotate            extension UITabBarController       public override func supportedInterfaceOrientations   - gt  Int           if let selected   selectedViewController               return selected supportedInterfaceOrientations                     return super supportedInterfaceOrientations             public override func shouldAutorotate   - gt  Bool           if let selected   selectedViewController               return selected shouldAutorotate                     return super shouldAutorotate             Swift 3  extension UINavigationController       open override var supportedInterfaceOrientations  UIInterfaceOrientationMask           return visibleViewController  supportedInterfaceOrientations    super supportedInterfaceOrientations            open override var shouldAutorotate  Bool           return visibleViewController  shouldAutorotate    super shouldAutorotate          extension UITabBarController       open override var supportedInterfaceOrientations  UIInterfaceOrientationMask           if let selected   selectedViewController               return selected supportedInterfaceOrientations                   return super supportedInterfaceOrientations            open override var shouldAutorotate  Bool           if let selected   selectedViewController               return selected shouldAutorotate                   return super shouldAutorotate           Now you can override the supportedInterfaceOrientations method or you can override shouldAutoRotate in the view controller you want to lock down otherwise you can leave out the overrides in other view controllers that you want to inherit the default orientation behavior specified in your app s plist  Disable Rotation  class ViewController  UIViewController       override func shouldAutorotate   - gt  Bool           return false           Lock to Specific Orientation  class ViewController  UIViewController       override func supportedInterfaceOrientations   - gt  Int           return Int UIInterfaceOrientationMask Landscape rawValue            In theory this should work for all complex view controller hierarchies  but I have noticed an issue with UITabBarController  For some reason it wants to use a default orientation value  See the following blog post if you are interested in learning about how to work around some of the issues    Lock Screen Rotation

If you are using navigationViewController you should create your own superclass for this and override   -  BOOL shouldAutorotate     id currentViewController   self topViewController     if   currentViewController isKindOfClass  SecondViewController class        return NO     return YES      this will disable rotation in SecondViewController but if you push your SecondViewController when your device is on portrait orientation then your SecondViewController will appear in portrait mode    Assume that you are using storyboard  You have to create manual segue  How to  and in your  onClick  method   -  IBAction onPlayButtonClicked  UIBarButtonItem   sender     NSNumber  value    NSNumber numberWithInt UIInterfaceOrientationLandscapeLeft       UIDevice currentDevice  setValue value forKey   orientation       self performSegueWithIdentifier   PushPlayerViewController  sender self       This will force landscape orientation before your superclass disable autorotate feature
