iOS8 GKLocalPlayerInternal无法识别的选择器 [英] iOS8 GKLocalPlayerInternal Unrecognized Selector

问题描述

刚刚在我的设备上安装了ios8，现在收到此错误：

Just installed ios8 on my device and am now receiving this error:

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

我没有在安装了ios7的其他两台设备上看到此错误。在安装了ios8的设备上，我已经通过设置验证GameCenter Sandbox已启用 - > GameCenter - >检查Sandbox

I do not see this error on two other devices with ios7 installed. On my device with ios8 installed I have already verified that GameCenter Sandbox is enabled by going to settings -> GameCenter -> Check "Sandbox"

我可以通过评论来避免错误输出以下代码：

I can avoid the error by commenting out this code below:

 // 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];
    }
})];

推荐答案

找到一个解决方案：似乎问题与游戏无关中心登录这么多......

Found a solution: doesn't seem like the problem was related to game center login so much...

我有一些代码采用以下形式：

I had a bit of code that took the form of:

-(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];

}

用这种形式替换代码解决了我的问题：

Replacing that code with something of this form solved my problem:

-(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...

}
