请帮帮我。

非常感谢。

这是iOS SDK 5/模拟器的一个已确认错误-只要模拟器尝试播放声音（来自电影或任何其他声音源），就会发生。不过别担心，在实际设备上不会有问题

您提到了用户在使用您的应用程序时遇到问题的实际报告-这些问题与您在上面发布的问题无关

该问题由苹果公司以Bug ID#10555404提交。我自己提交了一份报告，最终被确认为上述bug id的复制品

该问题目前一直持续到Xcode版本4.3.2（4E2002），iOS SDK 5.1

如果不正确地导入Mac OSX框架而不是iOs框架，则可能会出现此问题。删除Mac OS框架对我来说很有效

记住设置代理（self.player.delegate=self）并使用代理的方法清理：

-(void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)playedSuccessfully 
 {
       self.player = nil;
 }

仅关于第一部分：我想，您最近已经从Xcode 4.2更新到了4.3，并且使用了一个“旧”项目。因此，路径是不正确的，这并不重要，因为框架仍然存在。啊。。。我懂了。谢谢你的帮助。这是件好事，没关系。这是模拟器的SDK错误。如果您禁用异常断点或只是继续使用它们，那么实际上一切都可以正常工作。在设备上一切正常。哦！！非常感谢你！！好啊我将检查导入的框架。我将设置代理。非常感谢！！：当我在模拟器上测试我的场景时，视频和声音会在几秒钟后消失。在设备上，我得到了相同的错误结果…（使用最新的Xcode版本4.3.2进行测试）他是从那里复制的吗@波波，那么这个链接呢
