ios – 崩溃 – [AVPlayerItem _attachToPlayer：] AVPlayerItem不能与多个AVPlayer实例相关联

我遇到了大约10％的用户崩溃,但我无法再现它,并且不清楚这一切发生.

Crashlytics报道了大约一半的应用程序不重要的崩溃用户,即做背景音乐或AirPlay.应用程序播放HLS视频流,并在后台切换到仅音频版本.

任何想法有什么问题,或为什么会有多个AVPlayer实例从我的单身玩家类？

谢谢！

解决方法

似乎通过在设置新的URL之前明确地停止播放来解决.

[moviePlayer stop];
moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
[moviePlayer setContentURL:[NSURL URLWithString:[videos objectForKey:quality]]];
