推荐答案

检查

Check the useApplicationAudioSession property on MPMoviePlayerController. In iOS 3.1.x, the movie player was always getting its own system provided audio session. In iOS 4.0, it can now share the application session, and that's the default value as well. Try switching that property to NO before starting to play your movie.
