Trouble bringing up leaderboards with my code

I think you are missing the leaderboardViewControllerDidFinish: method. One implementation (that I haven't checked) could be the following, although I had found one-liners as well:


-(void)leaderboardViewControllerDidFinishGKLeaderboardViewController*)viewController{
CGRect frame = viewController.view.frame;
[UIView beginAnimations"curldoup" context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:.5];
[UIView setAnimationDidStopSelector:
@selector(animationDidStop:finished:context];
frame.origin.y = 480;
viewController.view.frame = frame;
[UIView commitAnimations];
}

 

My guess would be that you are just missing the required delegate template in the .h header:

Code:

@interface MyVC : UIViewController [B]<GKLeaderboardViewControllerDelegate>[/B] {

}

This delegate is required in any class that you assign to .leaderboardDelegate.

 

You can't pop a UIViewController directly from a CCLayer, you need to do it from within the context of another UIViewController.

First, expose your RootViewController as a property from your AppDelegate:
@property (nonatomic, retain) RootViewController *viewController;

Then, import your AppDelegate in your CCLayer.h file.

Next:

GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
leaderboardController.leaderboardDelegate = self;

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
RootViewController *vCont = appDelegate.viewController;
[vCont presentModalViewController:leaderboardController animated:YES];

[leaderboardController release];

 

Correct. It's just like popping a modal view controller in UIKit.

There are a number of people who have written sample code for this and suggest using a temporary view controller, but I prefer to do this against my app's root view controller as that seems to yield better results when dealing with orientation changes.

 

I had very similar issue, but I found a simple solution, like this:

HighscoreScene.h:

Code:

@interface HighscoreScene : [U]BaseScene[/U] [B]<GKLeaderboardViewControllerDelegate>[/B]
{
[I](...)[/I]
}

[I](...)[/I]
- (void) [B]showLeaderboard[/B];
- (void) [B]leaderboardViewControllerDidFinish[/B]:(GKLeaderboardViewController *)leaderboardVC;
[I](...)[/I]

(where BaseScene inherits from NSObject)

HighscoreScene.m:

Code:

- (void) [B]showLeaderboard[/B]
{
    UIWindow* window = [UIApplication sharedApplication].keyWindow;
	
    GKLeaderboardViewController *leaderboardVC = [[GKLeaderboardViewController alloc] init];   
    if (leaderboardVC != nil)
    {
	leaderboardVC.leaderboardDelegate = self;
		
	UIViewController *vc = [[UIViewController alloc] init];
	[window addSubview: vc.view];
        [vc presentModalViewController: leaderboardVC animated: YES];
    }
}

- (void)[B]leaderboardViewControllerDidFinish[/B]:(GKLeaderboardViewController *)leaderboardVC
{
    [leaderboardVC dismissModalViewControllerAnimated:YES];
    [leaderboardVC.view.superview removeFromSuperview];
    [leaderboardVC release];
}
