我正在使用MPMoviePlayerViewController播放MP4文件。它适用于小文件（例如25-30 MB），但在播放大文件（~150 MB）时会崩溃应用程序。
以下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];
任何建议伙伴/加尔斯。
