Question

我在获取排行榜时遇到问题。我想我没错，但我在日志中得到了这个错误

Unbalanced calls to begin/end appearance transitions for <UIViewController: 0x105e39c0>.

这是我显示和隐藏视图的代码

- (void)showLeaderboard
{
    GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
    if (leaderboardController != NULL)
    {   CCLOG( @" leaderboardController ok...");
        tempVC = [[UIViewController alloc] init];
        leaderboardController.leaderboardDelegate = self;
        [[[CCDirector sharedDirector] openGLView] addSubview:tempVC.view];

        leaderboardController.category =     @"com.bluemesasoftware.housedefender.hightestscore";

    leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;
    leaderboardController.leaderboardDelegate = self;
    [tempVC presentModalViewController: leaderboardController animated: YES];
}
}

- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController  
{
    [tempVC dismissModalViewControllerAnimated:YES];
    [tempVC.view.superview removeFromSuperview];
    [tempVC release];
}

Answer 1

[tempVC presentModalViewController: leaderboardController animated: NO]; 

[tempVC dismissModalViewControllerAnimated:YES];

这应该有用。

Answer 2

不要将视图添加到CCDirector的openglview

我假设你的AppDelegate中有这个代码...如果是这样的话：

[window.rootViewControler.view addSubview:tempVC.view];

而不是

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

也..在presentModalViewController

之前移动此代码
