我有一个播放声音的按钮,它似乎在模拟器上工作得很好,但我收到这条消息:

当我尝试播放任何视频时,我的MPMoviePlayerController崩溃了.

这只发生在模拟器上,在设备上正常工作.

错误如下:

MPMoviePlayerController 几秒后停止播放,这是我正在使用的代码:

NSString *urlAddress = @"http://67.159.28.74:8730";
NSURL *url = [NSURL URLWithString:urlAddress];

MPMoviePlayerController *player = [[MPMoviePlayerController alloc]initWithContentURL:url];
player.movieSourceType = MPMovieSourceTypeStreaming;

player.view.hidden = NO;
[self.view addSubview:player.view];
[player prepareToPlay];

if(player){
    [player play];
}

进入控制台的错误是:
