我试图通过使用cocos2d中通过使用http://www.raywenderlich.com/3325/how-to-make-a-simple-multiplayer-game-with-game-center-tutorial-part-22广东话接受游戏中心邀请
一切教程工作正常包括随机播放器自动匹配，但邀请朋友不起作用开发IOS的实时多人游戏因为其他设备无法收到邀请。
当我点击邀请朋友按钮，然后通过使用标准游戏中心界面选择一个朋友，它说等待（永远），没有任何反应。我的朋友无法收到游戏中心的邀请（没有通知）。
我可以通过使用附近的朋友功能（当两个设备上启用此功能时）邀请朋友，但在附近的朋友被禁用时没有邀请通知。
我花了几个小时在Google上搜索，发现类似的情况，但没有解决方案。
有关可能的答案，一些早期的反馈：
- 我使用两个设备（一部iPhone和一部iPad），没有模拟器
- iTunes上的所有设置连接都很好，包括多人游戏设置
- 我验证这两个设备通过使用不同的测试帐户连接到沙箱
- 我已经在两个设备上检查了游戏中心的通知设置
- 我已经检查了所有的代理/防火墙问题，并试图在WiFi和蜂窝两个设备
- 游戏邀请是为两个设备的启用/账户
- 我已经检查过的包ID，应用版本标识等...
- 两款器件是IOS 6.x和应用目标版本的操作系统IOS 5.0
- 我对游戏中心没有其他问题（排行榜，随机配对，等等......无一不精）
- 我在苹果文档中提到的尽可能验证用户身份之后尽快调用inviteHandler方法。
这里是我的游戏中心的辅助类的头文件：

的执行情况，最后，这是我如何从游戏层调用游戏中心（我尝试了两种不同的选项，但都没有工作）
选项1
[[GCHelper sharedInstance] findMatchWithMinPlayers:2 maxPlayers:2 viewController: [[[UIApplication sharedApplication] keyWindow] rootViewController] delegate: self];
选项2
AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
UINavigationController *viewController = [app navController];
[[GCHelper sharedInstance] findMatchWithMinPlayers:2 maxPlayers:2 viewController:viewController delegate:self];
任何帮助将不胜感激。在此先感谢...
