IOS8 GKLocalPlayerInternal Unrecognized Selector

Question

Just installed ios8 on my device, and now I get 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 already confirmed that GameCenter Sandbox is turned on by choosing settings → GameCenter → Check Sandbox

I can avoid the error by commenting on 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 shows this:

Any thoughts on this issue?

Thanks in advance!

Found a solution: it looks like the problem was with the login in the center of the game so much ...

I had some code that took the form:

 -(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 this code with something from 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 this helps!
