遊戲將不會向遊戲中心發送高分

Question

我已經設法讓我的遊戲在啓動時將玩家簽名到遊戲中心，但是當達到高分時，它會將其保存在遊戲中而不是發送到遊戲中心。只要我把

[self reportScore]; 

它似乎使模擬器崩潰，我重視我的看法Controller.m或者文件，如果你能幫助我的方法，使我的遊戲發送高分到遊戲中心，這樣我可以移動開始發佈排行榜以在應用中顯示排行榜。我順便說一句http://www.appcoda.com/ios-game-kit-framework/

    GKScore *score = [[GKScore alloc] initWithLeaderboardIdentifier:_leaderboardIdentifier]; 
    score.value = HighScoreNumber; 

    [GKScore reportScores:@[score] withCompletionHandler:^(NSError *error) { 
     if (error != nil) { 
      NSLog(@"%@", [error localizedDescription]); 
     } 
    }];

-(void)authenticateLocalPlayer;{ 
    GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer]; 

    localPlayer.authenticateHandler = ^(UIViewController *viewController, NSError *error){ 
     if (viewController != nil) {

       // Get the default leaderboard identifier.

你可以試試這個簡單的片斷是否適合您按照本教程？ _localPlayer引用了一個由認證處理程序設置的實例變量。

- (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"); 
    } 
} 

此代碼來自我的測試原型，我用它來解決遊戲邀請和評分提交工作。代碼提交的代碼沒有其他部分。
