Question

我想在我自己的游戏中显示leaderbord ....我正在使用以下方法，但注意到发生...我与rootview控制器混淆，因为我的游戏是在cocos2d开发的所以没有像dat一样:(

// Leaderboards

-(void) showLeaderboard
{
    if (isGameCenterAvailable == NO)
        return;

    GKLeaderboardViewController* leaderboardVC = [[[GKLeaderboardViewController alloc] init] autorelease];
    if (leaderboardVC != nil)
    {
        leaderboardVC.leaderboardDelegate = self;
        [self presentViewController:leaderboardVC];
    }
}
///
-(void) leaderboardViewControllerDidFinish:(GKLeaderboardViewController*)viewController
{
    [self dismissModalViewController];
    [delegate onLeaderboardViewDismissed];
}

///////

-(UIViewController*) getRootViewController
{
    return [UIApplication sharedApplication].keyWindow.rootViewController;
}
///
-(void) presentViewController:(UIViewController*)vc
{
    UIViewController* rootVC = [self getRootViewController];
    [rootVC presentModalViewController:vc animated:YES];
}

////
-(void) dismissModalViewController
{
    UIViewController* rootVC = [self getRootViewController];
    [rootVC dismissModalViewControllerAnimated:YES];
}

... 问候

我不知道，但它对我有用。如果有人能描述为什么这样工作的真正原因我将非常高兴....我通过appdelegate称呼它

[(myAppDelegate*)[[UIApplication sharedApplication] delegate]gameCenter];

从appdelegate我调用rootviewcontroller方法，如

-(void)gameCenter
{
    [rootViewController gameCenterLeaderboard];
}

并且在rootviewcontroller中有一个方法

-(void)gameCenterLeaderboard
{

    GKLeaderboardViewController* leaderboardVC = [[[GKLeaderboardViewController alloc] init] autorelease];
    if (leaderboardVC != nil) {

        leaderboardVC.leaderboardDelegate = self; 
        [self presentModalViewController: leaderboardVC animated: YES];


    }

}

以下方法也在rootviewcontroller中重写

- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)leaderboardController
{

    [self dismissModalViewControllerAnimated:YES];
}

如果您没有根UIViewController，那么我建议创建一个新的UIViewController，将它的视图设置为您的openGLView，然后使用该视图控制器将排行榜呈现为模态视图控制器。

UIViewController *leaderboardViewController = [[UIViewController alloc] init];
[leaderboardViewController setView:[[CCDirector sharedDirector] openGLView]];

[leaderboardViewController presentModalViewController:leaderboardVC animated:YES]; //leaderboardVC is your GKLeaderboardViewController
