Ios – Animating UICollectionView on orientation changes

Apple states:

Case: All child view controllers in your UITabBarController or UINavigationController do not agree on a common orientation set.

Response: To make sure that all your child view controllers rotate correctly, you must implement shouldAutorotateToInterfaceOrientation for each view controller representing each tab or navigation level. Each must agree on the same orientation for that rotate to occur. That is, they all should return YES for the same orientation positions.

You may be able to set device orientation within the navigation controller instead of within individual views. Then you could check which view is on the stack and rotate based on the result. In this way, the navigation controller handles all orientation as well.

You can use a separate view controller for MPMovieplayer. You don't have to override the

(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

in the original view controller.

if you are using MPMoviePlayerViewController, everything is already set nicely for you, as the method shouldAutorotateToInterfaceOrientation: will return YES by default. You can use it as a subview or present it modally by calling
presentMoviePlayerViewControllerAnimated:
