MPMoviePlayerController가 홈 화면으로 이동하면 앱이 백그라운드에서 실행되고 airPlay가 재생됩니다. 하지만 홈 버튼을 두 번 탭하면 앱이 다운됩니다. 이것은 iOS 5에서 발생하지만 4.3에서는 발생하지 않습니다.백그라운드에서 airPlay를 재생하는 MPMoviePlayerController, 홈 버튼을 두 번 탭하면 충돌이 발생합니다.
다른 코드를 제외하려면 버튼 만 눌렀을 때에 만 코드를 실행하는 새로운 빈 프로젝트를 만들었습니다.

나는 똑같은 문제가있었습니다. 그동안 매번 다른 앱을 시작하면 매번 그런 일이 발생하지 않았습니다. 장치가 더 많은 리소스를 필요로 할 때 MPMoviePlayerController의 뷰의 부모 뷰가 잘못 언로드되는 것으로 가정했습니다. – reddersky
