Question

我想为游戏实施ELO评级系统。这意味着在结束游戏之后，我必须计算胜利者的增加量，并从实际分数中减少松散度。

我的排行榜类型为＆＃34;最新分数＆＃34;只看到最后发送的分数。我使用loadScoresWithCompletionHandler来加载得分，然后计算（现在只是添加不同的值）然后使用endMatchInTurnWithMatchData：scores：achievement：completionHandler：用于结束匹配并更新得分。

GKTurnBasedParticipant* player1 = [match.participants firstObject];
    GKTurnBasedParticipant* player2 = [match.participants lastObject];
    GKLeaderboard *leaderboardRequest = [[GKLeaderboard alloc] initWithPlayerIDs:@[player1.playerID, player2.playerID]];
    leaderboardRequest.timeScope = GKLeaderboardTimeScopeAllTime;
    leaderboardRequest.identifier = LEADERBOARD_ELO_RATING_ID;

[leaderboardRequest loadScoresWithCompletionHandler:^(NSArray *scores, NSError *error) {
        if(error){
            NSLog(@"%@", error);
            return;
        }
        GKScore *player1Score = [scores firstObject];
        GKScore *player2Score = [scores lastObject];

        float score1 = ((float)player1Score.value) / 1000.0f;
        float score2 = ((float)player2Score.value) / 1000.0f;

        // calculation of new score
        score1 +=10;
        score2 +=1;

        GKScore *player1NewScore = [[GKScore alloc] initWithLeaderboardIdentifier:LEADERBOARD_ELO_RATING_ID forPlayer:player1Score.playerID];
        GKScore *player2NewScore = [[GKScore alloc] initWithLeaderboardIdentifier:LEADERBOARD_ELO_RATING_ID forPlayer:player2Score.playerID];

        player1NewScore.value = (int64_t)(score1 * 1000.0f);
        player2NewScore.value = (int64_t)(score2 * 1000.0f);

        [match endMatchInTurnWithMatchData:[game.board matchData]
                                    scores:@[player1NewScore, player2NewScore]
                              achievements:@[]
                         completionHandler:^(NSError *error) {
                             if(error){// todo handle error
                             }
                         }];
    }];

获得分数并上传新分数工作正常，但当我去看排行榜（使用GKGameCenterViewController或GameCenter应用程序）时，我只能看到本地玩家（已结束比赛并发送最终数据的参与者）的最新分数。但是如果我通过loadScoresWithCompletionHandler方法发出请求 - 我可以看到两个玩家的分数都被更新了 - 但是只有本地玩家才会在leaderboardController中显示。

示例：

Match started:
Player A - 10 pts
Player B - 10 pts
Match ended (Player A sent these scores using method endMatchInTurnWithMatchData:scores:achievements:completionHandler:):
Player A - 15 pts
Player B - 8 pts
Match ended - loadScoresWithCompletionHandler result shows scores:
Player A - 15 pts
Player B - 8 pts
Match ended - GKGameCenterViewController or GameCenter app shows scores:
Player A - 15 pts
Player B - 10 pts

为什么会这样，我做错了什么？是因为使用Game Center沙箱吗？否则我应该如何通过endMatchInTurnWithMatchData精确更新两个玩家的得分：得分：achievement：completionHandler：？

Answer 1

我发现，这可能只是因为使用了Game Center Sandbox。

通过endMatchInTurnWithMatchData：scores方法发送分数时，排行榜未显示所有更新的分数
