GameKitHelper：顯示Game Center排行榜

Question

我爲我的Cocos2d遊戲使用GameKitHelper。在某些時候，我想要顯示排行榜，所以我這樣做：

[[GameKitHelper sharedGameKitHelper] showLeaderboard]; 

但是沒有任何反應。我該怎麼辦？

Answer 1

顯示gameKit helper？它的錯誤..

它應該是這樣的：在這個環節

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

參考：Link

爲cocos2d的代碼..

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];
