MPMusicPlayerController在tvOS上无法播放音乐。

tvOS不支持MPMusicPlayerController的音乐播放功能。要实现音乐播放，可以使用AVPlayer或AVPlayerViewController。下面是代码示例：

// 创建AVPlayer NSString *urlStr = @"http://example.com/music.mp3"; NSURL *url = [NSURL URLWithString:urlStr]; AVPlayer *player = [AVPlayer playerWithURL:url];

// 开始播放 [player play];

// 创建AVPlayerViewController NSString *urlStr = @"http://example.com/music.mp3"; NSURL *url = [NSURL URLWithString:urlStr]; AVPlayer *player = [AVPlayer playerWithURL:url]; AVPlayerViewController *playerVC = [AVPlayerViewController new]; playerVC.player = player;

// 显示AVPlayerViewController [self presentViewController:playerVC animated:YES completion:nil];
