在iphone上集成coco2d中的游戏中心

Question

我有这个在视图中显示排行榜的代码

.h

UIViewController *presentingViewController;
{

@property (retain) UIViewController *presentingViewController;

.m

- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
    [presentingViewController dismissModalViewControllerAnimated:YES];
    [self.presentingViewController.view removeFromSuperview];
}
- (void)leaderboard
{

        GKLeaderboardViewController *lb = [[GKLeaderboardViewController alloc] init];
        if(lb != nil){
            lb.leaderboardDelegate = self;
            presentingViewController = [[UIViewController alloc] init];
            [[[[CCDirector sharedDirector] openGLView] window] addSubview:presentingViewController.view];
            [presentingViewController presentModalViewController:lb animated:YES];

}

每件事都很好，它显示了排行榜，当我点击完成按钮时，它会消失，但如果我点击游戏中心按钮，排行榜就不出来了，我们也无法浏览其他页面。

上面的代码有什么问题，这是针对iphone cocos2d应用程序的

提前谢谢。

我在cocos2D游戏中使用了这段代码，运行良好，

-(void)displayLeaderboard
{
    GKLeaderboardViewController *leaderboardViewController = [[GKLeaderboardViewController alloc] init];
    leaderboardViewController.leaderboardDelegate = self;

    AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];

    [app.navController presentModalViewController:leaderboardViewController animated:YES];
}


#pragma mark GameKit delegate

-(void) achievementViewControllerDidFinish:(GKAchievementViewController *)viewController
{
    AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
    [app.navController dismissModalViewControllerAnimated:YES];
}

-(void) leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
    AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
    [app.navController dismissModalViewControllerAnimated:YES];
}
