Question

我写了像bellow

这样的代码

    - (void)leaderboard {
    GKLeaderboardViewController *leaderboardController = [[[GKLeaderboardViewController alloc] init] autorelease];
    currentLeaderBoard = kLeaderboardID;
    if (leaderboardController != NULL) 
    {
        leaderboardController.leaderboardDelegate = self; 
        leaderboardController.category = currentLeaderBoard;
        leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime; 
        tempVC = [[UIViewController alloc] init];
        [[[[CCDirector sharedDirector] openGLView] window] addSubview:tempVC.view];
        [tempVC presentModalViewController:leaderboardController animated:YES];
    }
}


- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController
{
    [viewController dismissModalViewControllerAnimated:YES];
    [viewController release];
}

发出如下警告：

Assigning to 'id<GKLeaderboardViewControllerDelegate>' from incompatible type 'HelloWorldLayer *'

它还显示在日志视图中：

warning: class 'HelloWorldLayer' does not implement the 'GKLeaderboardViewControllerDelegate' protocol

我知道为什么会这样。即使游戏中心排行榜熄灭，菜单也会被禁用。我继续计算游戏，一切都变得禁用。

抱歉编辑后，我已经解决了问题的第二部分。我已在另一个视图中移动了排行榜视图。

您应该转到类接口并将GKLeaderboardViewControllerDelegate添加到已实现协议的列表中：

@interface HelloWorldLayer : CCLayer <GKLeaderboardViewControllerDelegate>

我无法理解的其余问题，你能解释一下吗？

cocos2d游戏中心和leaderboardViewControllerDidFinish
