[英]Crash in -[AVPlayerItem _attachToPlayer:] An AVPlayerItem cannot be associated with more than one instance of AVPlayer
[英]iOS 8.4 AVFoundation _attachToPlayer or _attachToFigPlayer crash | An AVPlayerItem cannot be associated with more than one instance of AVPlayer
我刚收到一个来自crashlytics的消息,说我的应用程序稳定性差强人意! 基本上,这是iOS的最新更新(8.4)崩溃的崩溃,并且在以前的版本中不存在。
您是否知道_attachToFigPlayer是什么,或者可能是什么原因导致的? 它发生在两个应用程序中,一个在Obj-c中,另一个在Swift中。
谢谢你们!
原始崩溃:(_attachToFigPlayer)

更新:
这是我在XCode中得到的错误
***由于未捕获的异常“ NSInvalidArgumentException”而终止应用程序,原因:“一个AVPlayerItem不能与一个以上的AVPlayer实例关联”
好的,这表明在使用MPMoviePlayerViewController并尝试重新使用播放器时会发生这种情况。 就我而言,我使用播放器作为子视图。
基本上,我的解决方法是将播放器设置为NULL,并在每次播放新视频时重新启动它。
代码:(请记住,我使用MPMoviePlayerViewController作为子视图)
- (void)initPlayer {
if (self.player != NULL) {
[self.player.view removeFromSuperview];
self.player = NULL;
}
self.player = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:movie]];
if (IsIPad()) {
width = 730;
height = 412;
} else {
width = 320;
height = 180;
}
self.player.view.frame = CGRectMake(0, 61, width, height);
self.player.view.hidden = true;
self.player.moviePlayer.fullscreen = false;
self.player.moviePlayer.controlStyle = MPMovieControlStyleEmbedded;
[self.viewController.view addSubview:self.player.view];
}
if(avPlayer==nil)
{
avPlayer = [AVPlayer playerWithPlayerItem:_avPlayerItem];
}else{
[avPlayer replaceCurrentItemWithPlayerItem:_avPlayerItem];
}
这样可以解决这类问题
