How do I programmatically set device orientation in iOS 7

Question

I am working on an iPad app  using AutoLayout  where if the user enables a certain mode   heads-up  mode   I want to support only portrait  or portrait upside down  orientation  and furthermore  if the device is in landscape  I d like to automatically switch to portrait mode   In the top view controller  I have the following   -  NSUInteger  supportedInterfaceOrientations       if  self modeHeadsUp            return UIInterfaceOrientationMaskPortrait   UIInterfaceOrientationMaskPortraitUpsideDown        else           return UIInterfaceOrientationMaskAll           -  BOOL  shouldAutorotate       return TRUE      Based on answers I ve seen elsewhere here  the answer seems to be that I should use  application setStatusBarOrientation   Therefore  in the method where the user has selected  heads-up  mode  I have included       UIApplication  application    UIApplication sharedApplication        application setStatusBarOrientation UIInterfaceOrientationPortrait                                 animated YES     However  this simply doesn t seem to do anything  While I can physically move the device to get it to rotate into portrait  it doesn t do so automatically   In fact  when in landscape mode after running the above code to attempt to programmatically set the orientation  when I query the application  statusBarOrientation  with the following code  it remains at  4  for landscape     UIApplication  application    UIApplication sharedApplication   int orientation    application statusBarOrientation   self movesTextView text    NSString stringWithFormat   ORIENTATION  d   orientation     It seemed like maybe autolayout wasn t being triggered with the setStatusBarOrientation  so I attempted to add this code after  to no effect        super updateViewConstraints        self view updateConstraints     I realize Apple wants to leave device orientation in the hands of the user  However  I d like to be able to support landscape mode when not in  heads-up  mode    Am I missing something to be able to force orientation change

You need to call attemptRotationToDeviceOrientation  UIViewController  to make the system call your supportedInterfaceOrientations when the condition has changed

This worked me perfectly      NSNumber  value    NSNumber numberWithInt UIDeviceOrientationPortrait     UIDevice currentDevice  setValue value forKey   orientation

I was in a similar problem than you  I need to lock device orientation for some screens  like Login  and allow rotation in others   After a few changes and following some answers below I did it by    Enabling all the orientations in the Project s Info plist       Disabling orientation in those ViewControllers where I need the device not to rotate  like in the Login screen in my case  I needed to override shouldAutorotate method in this VC    - BOOL shouldAutorotate      return NO     Hope this will work for you

If you want to lock the main view of your app to portrait  but want to open popup views in landscape  and you are using tabBarController as rootViewController as I am  you can use this code on your AppDelegate   AppDelegate h   interface AppDelegate   UIResponder  lt UIApplicationDelegate  UITabBarControllerDelegate gt    property  strong  nonatomic  UIWindow  window   property  strong  nonatomic  UITabBarController  tabBarController    end   AppDelegate m  -  BOOL application  UIApplication   application didFinishLaunchingWithOptions  NSDictionary   launchOptions       self window     UIWindow alloc  initWithFrame   UIScreen mainScreen  bounds            Create a tab bar and set it as root view for the application     self tabBarController     UITabBarController alloc  init       self tabBarController delegate   self      self window rootViewController   self tabBarController              -  NSUInteger tabBarControllerSupportedInterfaceOrientations  UITabBarController   tabBarController       return UIInterfaceOrientationMaskPortrait     -  UIInterfaceOrientation tabBarControllerPreferredInterfaceOrientationForPresentation  UITabBarController   tabBarController       return UIInterfaceOrientationPortrait      It works very well   In your viewController you want to be presented in landscape  you simply use the following   -  NSUInteger supportedInterfaceOrientations       return UIInterfaceOrientationMaskLandscape     -  BOOL shouldAutorotate       return YES

This solution lets you force a certain interface orientation  by temporarily overriding the value of UIDevice current orientation and then asking the system to rotate the interface to match the device s rotation   Important  This is a hack  and could stop working at any moment  Add the following in your app s root view controller   class RootViewController   UIViewController       private var  interfaceOrientation  UIInterfaceOrientation    portrait     override var supportedInterfaceOrientations  UIInterfaceOrientationMask   return UIInterfaceOrientationMask from   interfaceOrientation        override var preferredInterfaceOrientationForPresentation  UIInterfaceOrientation   return  interfaceOrientation        override func viewDidLoad             super viewDidLoad              Register for notifications         NotificationCenter default addObserver self  selector   selector RootViewController handleInterfaceOrientationChangeRequestedNotification       name   interfaceOrientationChangeRequested  object  nil             deinit   NotificationCenter default removeObserver self         func handleInterfaceOrientationChangeRequestedNotification   notification  Notification            guard let interfaceOrientation   notification object as  UIInterfaceOrientation else   return            interfaceOrientation   interfaceOrientation            Set device orientation            Important                 Passing a UIDeviceOrientation here doesn t work  but passing a UIInterfaceOrientation does                This is a hack  and could stop working at any moment         UIDevice current setValue interfaceOrientation rawValue  forKey   orientation              Rotate the interface to the device orientation we just set         UIViewController attemptRotationToDeviceOrientation            private extension UIInterfaceOrientationMask        init from interfaceOrientation  UIInterfaceOrientation            switch interfaceOrientation           case  portrait  self    portrait         case  landscapeLeft  self    landscapeLeft         case  landscapeRight  self    landscapeRight         case  portraitUpsideDown  self    portraitUpsideDown         case  unknown  self    portrait                    extension Notification Name       static let interfaceOrientationChangeRequested   Notification Name rawValue   interfaceOrientationChangeRequested       Make sure all interface orientations are checked under  Deployment Info      Request interface orientation changes where you need them   NotificationCenter default post name   interfaceOrientationChangeRequested  object  UIInterfaceOrientation landscapeRight

Add this statement into AppDelegate h    whether to allow cross screen marker   property  nonatomic  assign  allowRotation BOOL   Write down this section of code into AppDelegate m  -  UIInterfaceOrientationMask  application   UIApplication    supportedInterfaceOrientationsForWindow  application  UIWindow    window       If  self allowRotation            UIInterfaceOrientationMaskAll return            UIInterfaceOrientationMaskPortrait return     Change the allowRotation property of delegate app

This works for me on Xcode 6  amp  5   -  BOOL shouldAutorotate       return YES    -  NSUInteger supportedInterfaceOrientations       return  UIInterfaceOrientationMaskPortrait

The only way that worked for me is presenting dummy modal view controller   UIViewController  dummyVC     UIViewController alloc  init   dummyVC view     UIView alloc  init    self presentModalViewController dummyVC animated NO    self dismissModalViewControllerAnimated NO     Your VC will be asked for updated interface orientations when modal view controller is dismissed   Curious thing is that UINavigationController does exactly this when pushing popping child view controllers with different supported interface orientations  tested on iOS 6 1  7 0

If you have a UIViewController that should stay in Portrait mode  simply add this override and you re all set   override func supportedInterfaceOrientations   - gt  UIInterfaceOrientationMask       return UIInterfaceOrientationMask Portrait     The best part is there is no animation when this view is shown  it s just already in the correct orientation

Try this along with your code   - BOOL shouldAutorotateToInterfaceOrientation  UIInterfaceOrientation interfaceOrientation    - void willRotateToInterfaceOrientation  UIInterfaceOrientation toInterfaceOrientation duration  NSTimeInterval duration   once user select any option then call this method because user can be in landscape mode and then he can set only portrait mode in same view controller so automatically view should be moved to portrait mode so in that button acton call this  - void willRotateToInterfaceOrientation  UIInterfaceOrientation toInterfaceOrientation duration  NSTimeInterval duration

The base UINavigationController should have the below callback so that the child items can decide what orientation they want   - NSUInteger supportedInterfaceOrientations       UIViewController  topVC   self topViewController      return topVC supportedInterfaceOrientations     - BOOL shouldAutorotate      UIViewController  topVC   self topViewController     return  topVC shouldAutorotate

NSNumber  value    NSNumber numberWithInt UIInterfaceOrientationLandscapeLeft     UIDevice currentDevice  setValue value forKey   orientation      does work but you have to return shouldAutorotate with YES in your view controller  -  BOOL shouldAutorotate       return self shouldAutoRotate      But if you do that  your VC will autorotate if the user rotates the device     so I changed it to    property  nonatomic  assign  BOOL shouldAutoRotate   -  BOOL shouldAutorotate       return self shouldAutoRotate      and I call   -  void swithInterfaceOrientation  UIInterfaceOrientation orientation       self rootVC shouldAutoRotate   YES       NSNumber  value    NSNumber numberWithInt  orientation         UIDevice currentDevice  setValue value forKey   orientation        to force a new orientation with a button-click  To set back shouldAutoRotate to NO  I added to my rootVC  -  void didRotateFromInterfaceOrientation  UIInterfaceOrientation fromInterfaceOrientation       self shouldAutoRotate   NO      PS  This workaround does work in all simulators too
