使用MPMoviePlayerViewController进行视频播放时，真机可以，但是模拟器不可用，没有解决。。

- (IBAction)movie:(id)sender {

    

    NSString *path = [[NSBundle mainBundle]pathForResource:@"movie" ofType:@"MOV"];

    NSURL *URL = [[NSURL alloc]initFileURLWithPath:path];

    _moviePlayer = [[MPMoviePlayerViewController alloc]initWithContentURL:URL];

    [self presentMoviePlayerViewControllerAnimated:_moviePlayer];

    [_moviePlayer.moviePlayer play];

}
