GameKitHelper：显示Game Center排行榜

Question

我为我的Cocos2d游戏使用GameKitHelper。在某些时候，我想要显示排行榜，所以我这样做：

[[GameKitHelper sharedGameKitHelper] showLeaderboard]; 

但是没有任何反应。我该怎么办？

Answer 1

显示gameKit helper？它的错误..

它应该是这样的：在这个环节

- (void) showLeaderboard 
{ 
    GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init]; 
    if (leaderboardController != nil) 
    { 
     leaderboardController.leaderboardDelegate = self; 
     [self presentModalViewController: leaderboardController animated: YES]; 
    } 
}

为cocos2d的代码..

UIViewController* _tmpView = [[UIViewController alloc] initWithNibName:nil bundle:nil]; 
    GKLeaderboardViewController* gclb = [[GKLeaderboardViewController alloc] init]; 
gclb.leaderboardDelegate = self; 
    [[[CCDirector sharedDirector] openGLView] addSubview:_tmpView.view]; 
    [_tmpView presentModalViewController:gclb animated:NO];
