我目前正在开发 Game Center Multiplayer，但遇到了一些障碍。目前我下面的代码将验证他的用户显示媒人视图并开始一场比赛就好了。但是，当我尝试邀请朋友参加比赛时，当我接受时，要求进行比赛的警报视图会显示它会将我带到配对视图控制器并说它正在等待我另一台设备上的其他玩家它也说它正在等待让其他玩家回应。最终过了一段时间，它说邀请被取消了。我没有使用模拟器，我有 2 台设备，它们都有单独的游戏中心配置文件。一个是IOS 4.2，另一个是IOS 4.3。我不知道可能出了什么问题。我所有的多人游戏代码都在下面。此外，对于向任一设备发送数据，我很想知道一个好的网站来了解更多信息。我很高兴看到你们能想出什么。谢谢
