游戏将不会向游戏中心发送高分

Question

我已经设法让我的游戏在启动时将玩家签名到游戏中心，但是当达到高分时，它会将其保存在游戏中而不是发送到游戏中心。只要我把

[self reportScore]; 

它似乎使模拟器崩溃，我重视我的看法Controller.m或者文件，如果你能帮助我的方法，使我的游戏发送高分到游戏中心，这样我可以移动开始发布排行榜以在应用中显示排行榜。我顺便说一句http://www.appcoda.com/ios-game-kit-framework/

你可以试试这个简单的片断是否适合您按照本教程？ _localPlayer引用了一个由认证处理程序设置的实例变量。

- (IBAction)doAddAScore:(id)sender { 
    GKLocalPlayer *lp = [GKLocalPlayer localPlayer]; 
    NSInteger score = 100; 
    if (lp && lp.isAuthenticated) { 
     NSString *lbid = @"your.leaderboard.id"; 
     GKScore *gkScore = [[GKScore alloc] initWithLeaderboardIdentifier:lbid player:lp]; 
     gkScore.value = score; 
     [GKScore reportScores:@[gkScore] withCompletionHandler:^(NSError * _Nullable error) { 
      NSLog(@"GKScore::reportScores completed - error : %@", error); 
     }]; 
    } else { 
     NSLog(@"reporting score: localPlayer nil or not authenticated"); 
    } 
} 

此代码来自我的测试原型，我用它来解决游戏邀请和评分提交工作。代码提交的代码没有其他部分。
