我正在尝试检测本地玩家身份验证是否正常工作，而且似乎我总是得到肯定的结果。

这是我正在使用的代码：

//--------------------------------------------------------------
- (void)authenticateLocalPlayer 
{
    NSLog(@"Authenticating local player %@ (%d)", ([GKLocalPlayer localPlayer].authenticated? @"YES":@"NO"), [GKLocalPlayer localPlayer].authenticated);
    if ([GKLocalPlayer localPlayer].authenticated == NO) {
        [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) {
            [self callDelegateOnMainThread:@selector(authenticationChanged:) 
                                   withArg:nil 
                                     error:error];
        }];
    }
}

//--------------------------------------------------------------
- (void)authenticationChanged:(NSError *)error {
    if (error != nil) {
        NSLog(@"Error authenticating local player: %@", [error localizedDescription]);
    }
    NSLog(@"Authentication changed %@ (%d)", ([GKLocalPlayer localPlayer].authenticated? @"YES":@"NO"), [GKLocalPlayer localPlayer].authenticated);
}

我在断开网络连接时测试了这段代码，这是跟踪输出：

2010-12-13 13:20:59.799 LittleScreams[954:307] Authenticating local player NO (0)
2010-12-13 13:21:01.616 LittleScreams[954:307] Error authenticating local player: The Internet connection appears to be offline.
2010-12-13 13:21:01.621 LittleScreams[954:307] Authentication changed YES (1)

它清楚地看到连接已离线但仍在验证播放器！有什么想法吗？我在设备和模拟器上得到了相同的结果。

TIA

我认为您不应该手动调用 authenticationChanged，查看 Game Kit Programming Guide 并按照对我有用的步骤操作。
