推荐答案

在注册通知时，请确保player和player?.currentItem不等于nil.对我来说，似乎其中之一是nil，而您基本上是在订阅所有.AVPlayerItemDidPlayToEndTime通知(因为object是nil).

Make sure that player and player?.currentItem are not equal to nil when you're registering for notifications. To me, it seems like one of them was nil and you're basically subscribing to all of the .AVPlayerItemDidPlayToEndTime notifications (since object is nil).

为避免这种情况，请在将AVAsset分配给播放器后立即订阅通知.

To avoid that, subscribe to the notifications right after assigning AVAsset to the player.
