ContentURL XCDYouTubePlayer

Question

XCDYouTubePlayer，其初始化方式与使用MPMoviePlayerController相同。如何用这个播放多个视频（制作播放列表）。在MpMoviePlayerController中。我可以在播放电影时设置ContentUrl属性，然后在另一个电影结束时启动新电影。我怎么能在XCDYoutubePlayer中做到这一点呢？

XCDYouTubeVideoPlayerViewController *videoPlayerViewController =
[[XCDYouTubeVideoPlayerViewController alloc] initWithVideoIdentifier: [NSString stringWithFormat:@"%@", [[playlists valueForKey:@"link"] objectAtIndex:rowNow]]];

    [self presentMoviePlayerViewControllerAnimated: videoPlayerViewController];

以下是我对XCDYouTubeKit {/ 3}}的回复的副本。

首先，您需要取消注册MPMoviePlayerPlaybackDidFinishNotification，以便播放器不会在视频结束时自动关闭。

static void *MoviePlayerContentURLContext = &MoviePlayerContentURLContext;

- (IBAction) play:(id)sender
{
    self.videoPlayerViewController = [[XCDYouTubeVideoPlayerViewController alloc] initWithVideoIdentifier:firstVideoIdentifier];
    [[NSNotificationCenter defaultCenter] removeObserver:self.videoPlayerViewController name:MPMoviePlayerPlaybackDidFinishNotification object:self.videoPlayerViewController.moviePlayer];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(moviePlayerPlaybackDidFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.videoPlayerViewController.moviePlayer];
    [self.videoPlayerViewController addObserver:self forKeyPath:@"moviePlayer.contentURL" options:(NSKeyValueObservingOptions)0 context:MoviePlayerContentURLContext];
    [self presentMoviePlayerViewControllerAnimated:self.videoPlayerViewController];
}

然后您需要自己处理通知。管理 hasNextVideo 和 nextVideoIdentifier 对您有意义。

- (void) moviePlayerPlaybackDidFinish:(NSNotification *)notification
{
    MPMovieFinishReason finishReason = [notification.userInfo[MPMoviePlayerPlaybackDidFinishReasonUserInfoKey] integerValue];
    if (finishReason == MPMovieFinishReasonPlaybackEnded && [self hasNextVideo])
        self.videoPlayerViewController.videoIdentifier = [self nextVideoIdentifier];
    else
        [self dismissMoviePlayerViewControllerAnimated];
}

您还需要将自己注册为电影播放器​​contentURL的观察者，以自动开始播放下一个视频。

- (void) observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
    if (context == MoviePlayerContentURLContext)
        [self.videoPlayerViewController.moviePlayer play];
    else
        [super observeValueForKeyPath:keyPath ofObject:object change:change context:context];
}
