Question

我用c ++和100％opengl为iphone编写游戏我需要添加游戏中心，以便显示UIViews我必须做一些hackish。

void sb_socialShowAchievementsView(){
    SocialDelegate* del = [[[SocialDelegate alloc] init] autorelease];
    GKAchievementViewController *achievements = [[GKAchievementViewController alloc] init];
    if (achievements != nil) {
        achievements.achievementDelegate = del;
        HelperViewController* hvc = [[[HelperViewController alloc] init] autorelease];
        [globalGLView addSubview:hvc.view];
        [hvc presentModalViewController: achievements animated: YES];
    }
    [achievements release];
}

SocialDelegate实施协议GKAchievementViewControllerDelegate和GKLeaderboardViewControllerDelegate。

globalGLView是我的EAGLView个实例。

和HelperViewController只是一个UIViewController子类。

问题是，当我调用sb_socialShowAchievementsView()时，应用程序收到带有以下调用堆栈和消息的SIGABRT：

*** Assertion failure in -[UIButtonLabel setTextColor:], /SourceCache/UIKit_Sim/UIKit-1262.60.3/UILabel.m:312
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: color'

我无法得到我做错的事情......

我遇到了完全相同的问题。我有一个班级管理我几个月前写的所有游戏中心的东西，它工作得很好。我试图将它导入到一个新项目中，并调用标准方法来呈现GKAchievementViewController，然后它与你拥有的相同的SIGABRT崩溃了。然后我尝试首先验证播放器（在调用成就控制器之前我通常会这样做），问题就消失了。我想这是GameKit框架中的一个错误。我无法提交错误报告，因为错误报告显然有它自己的错误：）
