AVPlayer
An instance of AVPlayer cannot remove a time observer that was added by a different instance of AVPlayer.
解决办法
- (void)removeTimeObserver{
//[self.player removeTimeObserver:self.playbackTimeObserver];
@try{
[self.player removeTimeObserver:self.playbackTimeObserver];
}@catch(id anException){
//do nothing, obviously it wasn't attached because an exception was thrown
}
}
问题 原因 重复释放
playbackTimeObserver
