iOS 8游戏中心错误

Question

我更新了我的XCode和iOS。我的代码在更新之前运行良好。现在我无法登录游戏中心。控台给出这个错误

GameKitHelper ERROR: { 
    NSLocalizedDescription = "The requested operation could not be completed because this application is not recognized by Game Center."; 
} 

Answer 1

我找到了答案。 Sandbox在iOS 8中未启用。需要在设置 - >游戏中心 - >沙盒中启用沙箱。
