iOS8 GKLocalPlayerInternal Unrecognized Selector

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

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

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"

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];
    }
})];

The stack trace reveals this:

Any thoughts on this issue?

Thanks in advance!

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

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];

}

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...

}

Hope that helps!!
