objective-c - 用 MPMoviePlayer 播放电影——控件不会显示

Question

我想播放带有控件的电影——播放、停止、快进等。我使用以下代码:

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSURL *movieUrl = [NSURL fileURLWithPath:
                       [[NSBundle mainBundle] pathForResource:@"Spot" 
                                                       ofType:@"mp4"]];

    MPMoviePlayerController* myMovie=[[MPMoviePlayerController alloc] 
                                      initWithContentURL:movieUrl];

    //disable scaling of our movie
    myMovie.scalingMode = MPMovieScalingModeNone;
    [myMovie.view setFrame: myView.bounds];  
    [myView addSubview: myMovie.view];

    [[myMovie view] setFrame:[myView bounds]];
    myMovie.initialPlaybackTime = 2.0;

    [[NSNotificationCenter defaultCenter] addObserver:self 
                                             selector:@selector(movieFinished:) 
                                                 name:MPMoviePlayerPlaybackDidFinishNotification 
                                               object:myMovie]; 
    myMovie.scalingMode = MPMovieScalingModeAspectFill;
    myMovie.controlStyle = MPMovieControlStyleEmbedded;
    [myMovie play];
    // Do any additional setup after loading the view from its nib.
}

影片可以播放，但没有控件。谁能帮帮我？

试试这是否有效...

-(void)viewWillAppear:(BOOL)animated
{
    NSString *urlStr = [[NSBundle mainBundle] pathForResource:@"Spot.mp4" ofType:nil];
    NSURL *url = [NSURL fileURLWithPath:urlStr];
    moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
    [self.view addSubview:moviePlayer.view];
    moviePlayer.view.frame = CGRectMake(0, 0, 300, 400);  
    [moviePlayer play];
}

您将获得所有控件。
