Game Center身份验证错误 [英] Game Center authentication error

问题描述

我尝试调用游戏中心的身份验证方法，但是没有验证屏幕，并且回调返回一个错误：请求的操作已取消。

I'm trying to call the authentication method of game center, however no authentication screen comes up and the callback return with an error : "the requested operation has been canceled".

代码：

[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error)
     {
        NSDictionary *userInfo = nil;
        if (error == nil) {

            NSLog(@"Game Center successfully authenticated");
        }
        else {
            userInfo = [NSDictionary dictionaryWithObject:error forKey:@"NSError"];
        }
        [[NSNotificationCenter defaultCenter] postNotificationName:Notification
                                                            object:self
                                                          userInfo:userInfo];

    }];

任何想法可能导致此问题？

Any idea what can cause this issue ?

推荐答案

在iOS 4.2中，当用户取消登录游戏中心，3次尝试后返回错误。您可以通过使用Game Center应用程序登录，然后再次尝试您的应用程序来解决错误，您应该会在应用程序中看到来自Game Center的欢迎回复消息
