iOS编程陷井2，模拟器不可靠

同样的代码，模拟器下不工作，真机下可以循环播放。

MPMoviePlayerController *theMovie = [[MPMoviePlayerControlleralloc] initWithContentURL:[NSURLfileURLWithPath:[[NSBundlemainBundle] pathForResource:@"＊＊＊"ofType:@"mp4"] ]];

theMovie.repeatMode=MPMovieRepeatModeOne;

theMovie.view.frame = self.view.bounds;

[self.view addSubview:theMovie.view];

theMovie.scalingMode = MPMovieScalingModeAspectFill;
