这只发生在模拟器上,在设备上工作正常.

错误如下：

2012-10-25 16:46:24.033 TheFasterChef[8529:14303] [MPAVController] Autoplay: Disabling autoplay for pause

我的代码是调用MPMoviePlayerController的沼泽标准方法：

在.h文件中：

@property (retain) MPMoviePlayerController *videoPlayer;

在.m文件中：

NSBundle *appBundle = [NSBundle mainBundle];
//NSString *contentURLString = [appBundle pathForResource:videoIdentifier ofType:@"mp4"];
NSString *contentURLString = [appBundle pathForResource:@"test" ofType:@".mp4"];
NSURL *contentURL = [NSURL fileURLWithPath:contentURLString];

self.videoPlayer = [[MPMoviePlayerController alloc] initWithContentURL:contentURL];
[self.videoPlayer prepareToPlay];
[self.videoPlayer.view setFrame: self.view.bounds];
[self.view addSubview:self.videoPlayer.view];
[self.videoPlayer prepareToPlay];
[self.videoPlayer play];

我已经尝试这个代码片段在不同的视图控制器中具有相同的错误结果.

我已经在一个新的项目中尝试了这段代码,它的工作正常.

还有什么可能导致这个错误？

答案here没有为我解决.
