YTPlayerView youtube-ios-player-helper 暂停不起作用

我在使用 Youtube youtube-ios-player-helper 库时遇到问题.我可以将视频加载到播放器中并播放，但如果我点击暂停，视频会停止几秒钟，然后再次开始播放.

I'm having trouble with the Youtube youtube-ios-player-helper library. I can load a video into the player and it plays but if I tap pause the video stops for a few seconds and then starts playing again.

启动视频的极其简单的 UIViewController 代码是:

The incredibly simple UIViewController code to start the video is:

- (void)viewDidLoad {
    [super viewDidLoad];
    self.player = [[YTPlayerView alloc] initWithFrame:CGRectMake(X, Y, WIDTH, HEIGHT)];

    self.player.delegate = self;
    [self.view addSubview:self.player];
    [self.player loadWithVideoId:@"bQCjOm4p5jM"];

}

我使用 NSLog 检测 didChangeToState 委托方法如下:

I instrumented the didChangeToState delegate method with NSLog as follows:

- (void)playerView:(YTPlayerView *)playerView didChangeToState:(YTPlayerState)state {
    switch (state) {
        case kYTPlayerStatePlaying:
            NSLog(@"Started playback");
            break;
        case kYTPlayerStatePaused:
            NSLog(@"Paused playback");
            break;
        default:
            NSLog(@"didChangeToState %d", state);
            break;
    }
}

在 Xcode 日志中，当我点击播放"开始播放视频时，我看到:

In the Xcode log, when I tap 'play' to start the video playing, I see:

didChangeToState 4

值 4 似乎没有在 YTPlayerView.m 中定义.当视频真正开始播放时，我会看到预期的 Started play 日志消息.

The value 4 does not appear to be defined in YTPlayerView.m. When the video actually starts playing I see the expected Started playback log message.

当我点击暂停"时，我在日志中看不到任何内容(没有触发 didChangeToState 事件 - 我期望的事件是 kYTPlayerStatePaused 每个YTPlayerView 文档).然而，几秒钟后，视频又开始播放，然后我看到两个连续的 Startedplayed 日志消息(kYTPlayerStatePlaying 事件).每次我按暂停"尝试暂停视频时，它都会暂停几秒钟(没有 kYTPlayerStatePaused 事件)，但随后它又开始播放，我看到 Startedplayed代码> 日志消息.

When I tap 'pause', I don't see anything in the log (no didChangeToState event triggered - the event I'd expect would be kYTPlayerStatePaused per the YTPlayerView docs). However a few seconds later, the video starts playing again, and then I see two consecutive Started playback log messages (kYTPlayerStatePlaying events). Every time I press 'pause' to try to pause the video, it pauses for a few seconds (with no kYTPlayerStatePaused event), but then it starts playing again and I see Started playback log messages.

还有人看到这个吗?有谁知道从这里去哪里?这是 Xcode 6.2，构建目标是 iOS 8.0.

Anyone else seeing this? Anyone know where to go from here? This is Xcode 6.2 and build target is iOS 8.0.
