iOS8上GKLocalPlayerInternal无法识别的选择

刚装iOS8上我的设备上，我现在收到此错误：iOS8上GKLocalPlayerInternal无法识别的选择

-[GKLocalPlayerInternal name]: unrecognized selector sent to instance 0x1b6e3f80

我没有看到有ios7安装了两个其他设备此错误。在我的设备与iOS8上安装我已经验证了GameCenter的沙箱转到设置中启用 - > GameCenter的 - >检查“沙盒”

我可以通过注释掉下面这段代码避免错误：

// after checking that game center is available and authentication handler has not already been set, set the authentication handlers 
[localPlayer setAuthenticateHandler:(^(UIViewController* viewController, NSError *error) { 

    GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer]; 

    if (!error && viewController) 
    { 
     [self showAuthenticationDialogWhenReasonable: viewController fromBaseViewController:baseController]; 
    } 
    else if (localPlayer.isAuthenticated) 
    { 
     [self authenticatedPlayerandShowPopUpIfUnable:showPopUp]; 
    } 
    else 
    { 
     [self disableGameCenterandShowPopUpIfUnable:showPopUp]; 
    } 
})];

堆栈跟踪显示此：

找到了解决办法：似乎并不像这个问题是关系到游戏中心注册这么多...

我有一点的代码，把形式：

-(void) setAnnimationsPlaying:(BOOL)annimationsPlaying{ 

    ...some other code... 

    _annimationsPlaying = annimationsPlaying; 

    if (annimationsPlaying) 
     [self performSelector:@selector(xyz) withObject:nil afterDelay:0.1]; 

} 

-(void) xyz{ 

    if (!self.annimationsPlaying) 
     return; 

    ...some other code... 

    [self performSelector:@selector(xyz) withObject:nil afterDelay:6.0]; 

}

更换该代码与这种形式的东西解决了我的问题：

-(void) setAnnimationsPlaying:(BOOL)annimationsPlaying{ 

    ...some other code... 

    _annimationsPlaying = annimationsPlaying; 

    if (self.annimationsPlaying) { 
     [self xyz]; 
     self.timer = [NSTimer scheduledTimerWithTimeInterval:6.0f target:self selector:@selector(xyz) userInfo:nil repeats:YES]; 
    }else{ 
     [self.timer invalidate]; 
    } 

} 

-(void) xyz{ 

    if (!self.annimationsPlaying) 
     return; 

    ...some other code... 

}

希望帮助!!
