Preventing MPMoviePlayerController from Rotating When Parent View Controller Only Supports Portrait Orientation
MPMoviePlayerController Rotating in Full Screen While Parent View Controller Only Supports Portrait Orientation In iOS 6, Apple introduced a new rotation API to help developers implement rotation and orientation support for their applications. This API provides a way to restrict the supported interface orientations for a view controller, ensuring that the application only responds to specific device orientations. However, when using MPMoviePlayerController in full screen mode, the rotation behavior can become unpredictable, leading to unwanted rotation of the movie player.
