排行榜未显示在cocos2d屏幕中

Question

我使用下面的代码来显示排行榜，但是我只在控制台看到了以下内容。

cocos2d: surface size: 480x320

代码：

- (void)showLeaderboardForCategory:(NSString *)category
{
    // Only execute if OS supports Game Center & player is logged in
    if (hasGameCenter)
    {    

        // Create leaderboard view w/ default Game Center style
        GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];

        // If view controller was successfully created...
        if (leaderboardController != nil)
        {
            // Leaderboard config
            leaderboardController.leaderboardDelegate = self;   // The leaderboard view controller will send messages to this object
            leaderboardController.category = category;  // Set category here
            leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;    // GKLeaderboardTimeScopeToday, GKLeaderboardTimeScopeWeek, GKLeaderboardTimeScopeAllTime

            // Create an additional UIViewController to attach the GKLeaderboardViewController to
            myViewController = [[UIViewController alloc] init];

            // Add the temporary UIViewController to the main OpenGL view
            [[[CCDirector sharedDirector] openGLView] addSubview:myViewController.view];

            // Tell UIViewController to present the leaderboard
            [myViewController presentModalViewController:leaderboardController animated:YES];
        }
    }
}

最终，我像这样调用了代码：

    [[GameCenterManager sharedGameCenterManager] showLeaderboardForCategory:@"LeaderBoard"];

hasGameCenter 是全局变量吗？在这种情况下它可能是 false 值，因此不允许您进入吗？ - Grady Player

@Grady Player：不是没有假的，因为我在它后面使用了CCLOG（@“..”）并将文本记录到控制台。 - Bobj-C

[CCDirector sharedDirector] openGLView能否返回nil？ - Grady Player

Answer 1

我找到了解决方案，我必须写下来：

    [[[[CCDirector sharedDirector] openGLView] window] addSubview:myViewController.view];

替代：

    [[[CCDirector sharedDirector] openGLView] addSubview:myViewController.view];
