objective-c – 以编程方式显示MPMoviePlayerController中的控件

我有一个MPMoviePlayerController子类,应该在播放完成后显示控件.我已将响应者附加到MPMoviePlayerPlaybackDidFinishNotification通知,并尝试按如下方式设置控件样式：

[self setControlStyle:MPMovieControlStyleEmbedded];

这不起作用.从本质上讲,在视频结尾我想控制显示.

如何以编程方式显示控件？

注意：控制器未处于全屏模式.

请找到关于此的完整代码,它正在与我合作

添加.h类添加此项

@property(strong,nonatomic) MPMoviePlayerViewController * moviePlayer;

在.m类添加此代码“传递电影URl”

-(void) playMovie:(NSString *)filePath
{
    NSURL *theOutputURL = [NSURL fileURLWithPath:filePath];
    if(_moviePlayer)
        [_moviePlayer.moviePlayer setContentURL:theOutputURL];
    else
        _moviePlayer = [[MPMoviePlayerViewController alloc] initWithContentURL:theOutputURL];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(myMovieFinishedCallback:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:_moviePlayer.moviePlayer];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerPlaybackStateDidChange:) name:MPMoviePlayerPlaybackStateDidChangeNotification object:_moviePlayer.moviePlayer];

    if (![_moviePlayer.moviePlayer isPreparedToPlay])
        [_moviePlayer.moviePlayer prepareToPlay];

    _moviePlayer.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
    [_moviePlayer.moviePlayer setFullscreen:YES];
    _moviePlayer.moviePlayer.controlStyle=MPMovieControlStyleEmbedded;
    [_moviePlayer.moviePlayer setContentURL:theOutputURL];
    _moviePlayer.view.frame = CGRectMake(0, 0, [[UIScreen mainScreen]bounds].size.width, [[UIScreen mainScreen]bounds].size.height);
    [_moviePlayer shouldAutorotateToInterfaceOrientation: AVCaptureVideoOrientationLandscapeRight];
    [self.view addSubview:_moviePlayer.view];
}


- (void) moviePlayerPlaybackStateDidChange: (NSNotification *) notification {
    if (_moviePlayer.moviePlayer.playbackState == MPMoviePlaybackStateStopped) {
        [_moviePlayer.moviePlayer setContentURL:[_moviePlayer.moviePlayer contentURL]];
        [_moviePlayer.moviePlayer play];
    }
}

-(void)myMovieFinishedCallback:(NSNotification*)aNotification
{
    //  to add your code after playback is finished

}
