我刚刚收到一个消息表示崩溃,我的应用程序稳定性到地狱！基本上这是崩溃,随着iOS(8.4)中的最后一次更新而爆炸,并且在以前的版本中是不存在的.
你有什么想法_attachToFigPlayer是什么或可能发生的是导致这个？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XCode中出现的错误
***由于未捕获的异常’NSInvalidArgumentException’终止应用程序,原因：’AVPlayerItem不能与多个AVPlayer实例相关联’
解决方法
好的,当使用MPMoviePlayerViewController并尝试重新利用播放器时,会发生这种情况.在我的情况下,我正在使用播放器作为子视图.
基本上我的修复是设置NULL的播放器,并重新启动,每次我会播放一个新的视频.
代码：(记住我正在使用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];
}
