iOS 6 revert orientation after dismissModalViewController
ios, ios6
Solution
I think your problem is caused by this line (you have it twice in your code):
return UIInterfaceOrientationPortrait;
I'm currently trying to do s.th. similar to what you try to achieve, and have asked my question here: iOS 6 auto rotation issue - supportedInterfaceOrientations return value not respected
The problem with your code is that the two methods don't return an interface orientation but rather a mask that encodes in its bits a combination of allowed or preferred orientations.
Try this:
return UIInterfaceOrientationMaskPortrait;
`UIInterfaceOrientationPortrait` is mapped to 0 as far as I know and is thus interpreted as the empty set of interface orientations (none).
Problem
I have a `UITabBarViewController` in portrait mode where I push a `modalViewController` in landscape. The rotation changes to landscape when I push the modal, but when I dismiss it the orientation remains in landscape instead of reverting to portrait. Code: a `CustomUINavigationController` for the landscape mode: ``` - (BOOL)shouldAutorotate { return [[self.viewControllers lastObject] shouldAutorotate]; } - (NSUInteger)supportedInterfaceOrientations { return [[self.viewControllers lastObject] supportedInterfaceOrientations]; } - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation { return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation]; } ``` the uitabbarcontroller ``` - (BOOL)shouldAutorotate { if ([self inModal]) { UINavigationController *nav = (UINavigationController *)self.modalViewController; return [[nav.viewControllers lastObject] shouldAutorotate]; } else { return NO; } } -(NSUInteger)supportedInterfaceOrientations { if ([self inModal]) { UINavigationController *nav = (UINavigationController *)self.modalViewController; return [[nav.viewControllers lastObject] supportedInterfaceOrientations]; } else { return UIInterfaceOrientationPortrait; } } - (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation { if ([self inModal]) { UINavigationController *nav = (UINavigationController *)self.modalViewController; return [[nav.viewControllers lastObject] preferredInterfaceOrientationForPresentation]; } else { return UIInterfaceOrientationPortrait; } } - (BOOL)inModal { if (self.modalViewController && [self.modalViewController isKindOfClass:[UINavigationController class]]) { return YES; } else { return NO; } } ``` If I set shouldRotate to YES I get an error: * Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason: 'Supported orientations has no common orientation with the application, and shouldAutorotate is returning YES. Even though I have set the two orientations in UISupportedDeviceOrientations.
