使用MPMoviePlayerController时,“播放”按钮周围有“下一步”和“上一步”按钮。

单击通知时如何获取通知? 是否有方法向MPMoviePlayerController提供内容列表(数组)?

Nathan说得对,如果你想要按钮通知,就需要为播放器实现自己的UI。不过,您可以从播放器获得有关播放状态的通知。

- (void) registerForMediaPlayerNotifications {

    NSNotificationCenter *notificationCenter = [NSNotificationCenter defaultCenter];

    [notificationCenter addObserver: self
                           selector: @selector (handle_NowPlayingItemChanged:)
                               name: MPMusicPlayerControllerNowPlayingItemDidChangeNotification
                             object: musicPlayer];

    [notificationCenter addObserver: self
                           selector: @selector (handle_PlaybackStateChanged:)
                               name: MPMusicPlayerControllerPlaybackStateDidChangeNotification
                             object: musicPlayer];

    /*
     // This sample doesn't use libray change notifications; this code is here to show how
     //     it's done if you need it.
     [notificationCenter addObserver: self
     selector: @selector (handle_iPodLibraryChanged:)
     name: MPMediaLibraryDidChangeNotification
     object: musicPlayer];

     [[MPMediaLibrary defaultMediaLibrary] beginGeneratingLibraryChangeNotifications];
     */

    [musicPlayer beginGeneratingPlaybackNotifications];
}

MPMoviePlayerController* moviePlayer = [[MPMoviePlayerController alloc]
    initWithContentURL:someUrl];
moviePlayer.movieControlMode = MPMovieControlModeHidden;
[moviePlayer play];

NSArray* windows = [[UIApplication sharedApplication] windows];
if ([windows count] > 1) {
  UIWindow *moviePlayerWindow = [[UIApplication sharedApplication] keyWindow];
  [moviePlayerWindow addSubview:yourCustomOverlayView];
}

不理想,但标准控件很容易重新实现。

我认为你对这件事没有多少控制权 MPMoviePlayerController . 它是一个标准组件,基本上可以开始和停止播放电影,而不需要其他任何东西。
