音频播放器在iPhone中播放远程音频文件？

我需要在iPhone中从网站播放音频文件（.wav）。我正在使用MPMoviePlayerViewController来播放音频播放器。有时候应用程序正在崩溃。音频播放器在iPhone中播放远程音频文件？

我的代码：

NSURL * videoURL = [NSURL URLWithString：appDelegate.selectedQuestion.GraphicsUrl];

 videoPlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:videoURL]; 
     [[MPMusicPlayerController applicationMusicPlayer] setVolume:1.0]; 
     MPMoviePlayerController *moviePlayer = [videoPlayer moviePlayer]; 

     [moviePlayer setScalingMode:MPMovieScalingModeAspectFit]; 
     [videoPlayer.view setFrame: videoView.bounds]; 
     [moviePlayer.view setFrame:videoPlayer.view.bounds]; 
     [moviePlayer.backgroundView setFrame:videoPlayer.view.bounds]; 
     [videoView addSubview:videoPlayer.view]; 

     [moviePlayer setShouldAutoplay:NO]; 
     [moviePlayer setFullscreen:YES]; 
     [moviePlayer setFullscreen:NO]; 
     [moviePlayer setCurrentPlaybackTime:(NSTimeInterval)1]; 
     [moviePlayer setInitialPlaybackTime:(NSTimeInterval)1]; 
     [moviePlayer setControlStyle:MPMovieControlStyleDefault]; 
     [moviePlayer setCurrentPlaybackTime:(NSTimeInterval)-1];

我不知道你为什么使用两个实例（videoPlayer，moviePlayer）？如果您看到崩溃，则显示：'一个AVPlayerItem不能与多个AVPlayer实例关联'。另外，我不知道方法 - [MPMoviePlayerController moviePlayer]。要删除音频播放，您可以参考几个问题。 – Ravin 2012-01-05 11:31:51

我以前遇到死机一样，我通过删除所有的MPMoviePlayerController通知固定它也释放出的MPMoviePlayerController本身（注意，这两个应该做的，否则崩溃仍会发生！）一旦播放状态转到MPMoviePlaybackStateStopped。我仍然不知道确切的原因，只有我知道的是，如果玩家不断进入MPMoviePlaybackStateStopped状态，它会崩溃，所以我只是阻止它停止两次。

希望这会有所帮助。
