GKLeaderboard只返回localPlayer的分数

Question

我正在尝试通过GameKit实现记分板，而我遇到的问题是我的查询只返回localPlayer的分数。我已经在itunes connect中设置了两个测试用户，并且他们两个都看到了这个问题，它只返回当前登录的任何玩家的最高分，并且根本不返回其他玩家的分数。我有一个表视图，其中包含两个数组，一个用于玩家分数，一个用于玩家名称。

- (void)loadGlobalHighScores
{
    GKLeaderboard *leaderboard = [[GKLeaderboard alloc] init];
    leaderboard.identifier = @"MyLeaderBoardIdentifier";
    leaderboard.playerScope = GKLeaderboardPlayerScopeGlobal;
    leaderboard.timeScope = GKLeaderboardTimeScopeAllTime;
    leaderboard.range = NSMakeRange(1, 100);

    [leaderboard loadScoresWithCompletionHandler:^(NSArray *scores, NSError *error) {
        NSMutableArray *playerIDs = [NSMutableArray array];
        NSMutableArray *playerScores = [NSMutableArray array];
        for (GKScore *score in scores)
        {
            [playerIDs addObject:score.playerID];
            [playerScores addObject:[NSNumber numberWithLongLong:score.value]];
        }

        self.playerScores = playerScores;

        [GKPlayer loadPlayersForIdentifiers:playerIDs withCompletionHandler:^(NSArray *players, NSError *error) {
            NSMutableArray *playerNames = [NSMutableArray array];
            for (GKPlayer *player in players)
            {
                [playerNames addObject:player.displayName];
            }
            self.playerNames = playerNames;

            [self.highScoresTable reloadData];
        }];
    }];
}

据我所知，我做的一切都是正确的，我不确定这是测试用户帐户的问题还是什么。
