Hi:

I seem to be getting many leaks when I display the basic GameKit Leaderboard. Here is the code I use to create it:

- (void) showLeaderboard{

     if ( ![[GKLocalPlayer localPlayer] isAuthenticated]  ) {

          [self authenticateLocalPlayer];

          return;

     }

    leaderboardController = [[GKLeaderboardViewController alloc] init];

    leaderboardController.category = @"test1";

     if (leaderboardController != nil){

             leaderboardController.leaderboardDelegate = self;

          leaderBoardView = [[[UIViewController alloc] init] retain];

          [[[CCDirector sharedDirector] openGLView] addSubview:[leaderBoardView view]];

          [leaderBoardView presentModalViewController: leaderboardController animated: YES];

         }

}

And here are the leaks I am getting as soon as the Leaderboard shows.

Has anybody experienced this? I assume it is not normal behaviour?

Many thanks in advance:

are you sure 'leaderBoardView' it's being released properly? it is getting two retains (one with 'alloc' and another with 'retain').
also, you can use your application's UIViewController to present the leaderboard, instead of creating a new one.

I think I added that retain in when I was trying every combination to get it working. Ill remove it :)

How would I access the UIViewController from within a layer so I can call presentModalViewController?

A ha... is this it?

YourAppDelegate *appDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];

appDelegate.viewController <---this?

I tried that but still has the leak. I'm starting to think its a 'standard' leak in the GameKit framework. Can you confirm if you do or dont get a leak?

Hey John,
Did you manage to find the cause of this?
I'm experiencing the same problem.

Thanks
Martin.

I have the same problem, but only on the device, not on the simulator. Strange...

@orangewise

I have the same problem, only on the device.
I've been trying and searching to find a solution for two days now.
Any luck any body?
