Question

I have write the code like bellow

    - (void)leaderboard {
    GKLeaderboardViewController *leaderboardController = [[[GKLeaderboardViewController alloc] init] autorelease];
    currentLeaderBoard = kLeaderboardID;
    if (leaderboardController != NULL) 
    {
        leaderboardController.leaderboardDelegate = self; 
        leaderboardController.category = currentLeaderBoard;
        leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime; 
        tempVC = [[UIViewController alloc] init];
        [[[[CCDirector sharedDirector] openGLView] window] addSubview:tempVC.view];
        [tempVC presentModalViewController:leaderboardController animated:YES];
    }
}


- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
    [viewController dismissModalViewControllerAnimated:YES];
    [viewController release];
}

警告如下:

Assigning to  id<GKLeaderboardViewControllerDelegate>  from incompatible type  HelloWorldLayer *

记录还显示:

warning: class  HelloWorldLayer  does not implement the  GKLeaderboardViewControllerDelegate  protocol

I count find out why it is. and even when the game center leader board goes out then the menu becomes disable. I count continue with the game everything becomes disable.

sorry for the post editing i have solved the second part of the problem by myself. I have shifted the leaderboard view in another view.

您应进入班级接口,在已执行议定书清单中加入GKLeaderatViewControllerDelegate:

@interface HelloWorldLayer : CCLayer <GKLeaderboardViewControllerDelegate>

我无法理解的其余问题,你能否说几句?
