iphone - MPMoviePlayerViewController 加载大视频文件时应用程序崩溃

Question

我正在使用 MPMoviePlayerViewController 播放 MP4 文件。它对于小文件（例如 25-30 MB）运行完美，但在播放大文件（~150 MB）时它会导致应用程序崩溃。

下面是我正在使用的代码：

MPMoviePlayerViewController *playerViewController = [[MPMoviePlayerViewController   alloc]initWithContentURL:url];
playerViewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentMoviePlayerViewControllerAnimated:playerViewController];

player = [playerViewController moviePlayer];

[player prepareToPlay];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerInterruptByUser:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:playerViewController.moviePlayer];

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playerFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:playerViewController.moviePlayer];

[player play];

任何建议的家伙/女孩。
