我正在使用框架直接在横向模式下播放视频AVPlayerViewController。AVKit我想知道如何显示字幕。我进行了搜索，但没有找到任何解决方案。我MPMoviePlayerViewController用于播放视频，但由于它在 IOS 9 及更高版本中已贬值，我正在使用AVKit.

    NSURL *videoURL = [NSURL URLWithString:video.videoLink];
    AVPlayer *newPlayer = [AVPlayer playerWithURL:videoURL];
    AVPlayerViewController *playerViewController = [AVPlayerViewController  new];
    playerViewController.player = newPlayer;

    int32_t timeScale = newPlayer.currentItem.asset.duration.timescale;
    CMTime seektime=CMTimeMakeWithSeconds(startPlayBackTime, timeScale);

    [playerViewController.player seekToTime:seektime toleranceBefore:kCMTimeZero toleranceAfter:kCMTimeZero];

     }


    [playerViewController.player play];
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(playerItemDidReachEnd:)
                                                 name:AVPlayerItemDidPlayToEndTimeNotification
                                               object:[newPlayer currentItem]];

    playerViewController.player.closedCaptionDisplayEnabled = YES;
    [self presentViewController:playerViewController animated:YES completion:nil];

它运行良好，但问题是我无法显示字幕。我发现很少有字幕示例，但都AVPlayer用作子视图，所以这些方法对我不起作用。

知道如何实现这一目标吗？

谢谢 ！！
