假设iOS 3.2或更高版本.使用最初隐藏的控件进行移动的命令的正确顺序是什么.当电影正在播放时,用户可以选择在屏幕上标记并显示控件.

谢谢!

我的(控件未隐藏)代码:

- (void)playMovie
{
    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Test" ofType:@"m4v"]];  
    MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];  

    // Register to receive a notification when the movie has finished playing.  
    [[NSNotificationCenter defaultCenter] addObserver:self  
                                             selector:@selector(movieDone:)  
                                                 name:MPMoviePlayerPlaybackDidFinishNotification  
                                               object:moviePlayer];  

    [[NSNotificationCenter defaultCenter] addObserver:self  
                                             selector:@selector(movieState:)  
                                                 name:MPMoviePlayerNowPlayingMovieDidChangeNotification  
                                               object:moviePlayer];  

    [[NSNotificationCenter defaultCenter] addObserver:self 
                                             selector:@selector(movieReady:) 
                                                 name:MPMoviePlayerLoadStateDidChangeNotification 
                                               object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willEnterFullScreen:) name:MPMoviePlayerWillEnterFullscreenNotification object:moviePlayer];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willExitFullScreen:) name:MPMoviePlayerWillExitFullscreenNotification object:moviePlayer];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didFinishPlayback:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];
