我正在使用一个应用程序,让我可以使用iPhone远程在iPad上播放不同的视频.我一直跟随一个视频播放器的苹果示例,但我已经有一些麻烦.视频播放很好,我可以让它从各种视频播放,但在它们之间切换几次,它会崩溃,我得到这个在调试器：
*** Terminating app due to uncaught exception 'NSInvalidArgumentException',reason: 'An AVPlayerItem cannot be associated with more than one instance of AVPlayer' *** First throw call stack: (0x380da8bf 0x37c261e5 0x30acbcb5 0x30abc1f7 0x30ac3bf3 0x30c93d55 0x30c95f7b 0x380ad2dd 0x380304dd 0x380303a5 0x37e07fcd 0x31bb0743 0x25e5 0x257c)
这是我用来创建播放器的代码：
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentOfURL:movieURL];
if (player) {
[self setMoviePlayerController:player];
[self installMovieNotificationObservers];
[player setContentURL:movieURL];
[player setMovieSourceType:sourceType];
[self applyUserSettingsToMoviePlayer];
[self.view addSubview:self.backgroundView];
[player.view setFrame:self.view.bounds];
[player.view setBackgroundColor = [UIColor blackColor];
[self.view addSubview:player.view];
}
而当当前电影停止时,我使用：
[[self moviePlayerController] stop]; MPMoviePlayerController *player = [self moviePlayerController]; [player.view removeFromSuperview]; [self removeMovieNotificationHandlers]; [self setMoviePlayerController:nil];
编辑：
所以我现在发现,每当我尝试和转换视频第11次.奇怪的！我几乎把我的头发拉出来
解决方法
什么修复了我的这个问题是在执行setContentURL之前停止MPMoviePlayerController.
MPMoviePlayerController *streamPlayer;
[streamPlayer stop];
[streamPlayer setContentURL:[NSURL URLWithString:selectedStation]];
