preferredInterfaceOrientationForPresentation must return a supported interface orientation

Question

This error doesn't make sense, as the preferred orientation UIInterfaceOrientationLandscapeRight is returned by the supported orientation

//iOS6  -(BOOL)shouldAutorotate {     return NO; }  -(NSUInteger)supportedInterfaceOrientations {     return (UIInterfaceOrientationLandscapeRight | UIInterfaceOrientationLandscapeLeft); }  - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {     return UIInterfaceOrientationLandscapeRight; } 

Error :

Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'preferredInterfaceOrientationForPresentation must return a supported interface orientation!'

Answer 1

Your code should look like this:

-(BOOL)shouldAutorotate {     return NO; }  -(NSUInteger)supportedInterfaceOrientations {     return UIInterfaceOrientationMaskLandscape; }  - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {     return UIInterfaceOrientationLandscapeRight; } 

Also, make sure in your Info.plist you have set the correct orientations for you app because what you return from supportedInterfaceOrientations is intersected with the Info.plist and if it can't find a common one then you'll get that error.

Answer 2

supportedInterfaceOrientations is only called, if shouldAutorotate is set to YES

- (BOOL)shouldAutorotate {     return YES; }  - (NSUInteger)supportedInterfaceOrientations {     return UIInterfaceOrientationMaskLandscape; }  - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {     return UIInterfaceOrientationLandscapeRight; } 

The easiest approach for me, is only to set the Info.plist

If you like to support iOS 5 use this code in your view controllers.

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return UIInterfaceOrientationIsLandscape(interfaceOrientation); }
