Undefined behaviour of GameCenter leaderboards with SpriteKit

Question

I tried to present leaderboards via this code block

if ([GKLocalPlayer localPlayer].isAuthenticated) {
    GKGameCenterViewController *gameCenterController = [[GKGameCenterViewController alloc] init];
    if (gameCenterController != nil)
    {
        gameCenterController.gameCenterDelegate = self;
        gameCenterController.viewState = GKGameCenterViewControllerStateLeaderboards;
        UIViewController *vc = self.view.window.rootViewController;
        [vc presentViewController: gameCenterController animated:YES completion:Nil];
    }
    }else{
            UIAlertView *message = [[UIAlertView alloc] initWithTitle:@"You must enable Game Center"
                                                              message:@"Sign in through the Game Center app to enable all features"
                                                             delegate:nil
                                                    cancelButtonTitle:@"OK"
                                                    otherButtonTitles:nil];
            [message show];
    }

And if I enabled all exception breakpoints, it will crash in the moment leaderboards are presented. When i delete this breakpoints, everything works fine. I am login into Game Center with test user. Is this a glitch or what ?

Answer 1

I solved it via editing exception breakpoint from all to Objective-C exceptions . Tnx @LearnCocos2D for the answer
