在排行榜上获得本地玩家的位置

我正在编写自定义排行榜,我只想知道玩家ID,他/她在排行榜上的位置。

我找到了这个帖子:Rank of Local authenticated player in All Time best in game center leaderboard

但是我在实施它时遇到了麻烦。这就是我所拥有的:

-(void) retrieveScoresForPlayers:(NSArray*)players
                        category:(NSString*)category
                           range:(NSRange)range
                     playerScope:(GKLeaderboardPlayerScope)playerScope
                       timeScope:(GKLeaderboardTimeScope)timeScope
{
    if (isGameCenterAvailable == NO)
        return;

    GKLeaderboard* leaderboard = nil;
    if ([players count] > 0)
    {
        //leaderboard = [[[GKLeaderboard alloc] initWithPlayerIDs:players] autorelease];
        leaderboard = [[[GKLeaderboard alloc] initWithPlayerIDs:[NSArray arrayWithObject:[GKLocalPlayer localPlayer]]] autorelease];
    }
    else
    {
        leaderboard = [[[GKLeaderboard alloc] init] autorelease];
        leaderboard.playerScope = playerScope;
    }

    if (leaderboard != nil)
    {
        leaderboard.timeScope = timeScope;
        leaderboard.category = category;
        leaderboard.range = range;

        [leaderboard loadScoresWithCompletionHandler:^(NSArray* scores, NSError* error)
         {
             [self setLastError:error];
             //[delegate onScoresReceived:scores];
             if (_gkhDelegate != NULL) {
                 _gkhDelegate->onScoresReceived([self convertNSArrayOfGKScoresToCppVector:scores]);
             }
         }];
    }
}

每当我打印等级时,无论实际数量如何,它始终为1。我怀疑它在查询中返回排名。如何返回排行榜中的绝对位置?

1 个答案:

答案 0 :(得分:0)

看起来在收到分数后,它会调用onScoresReceived委托方法并传入分数向量。

您将需要实现该委托方法,以便您可以获取分数和矢量的向量。如果需要,可以按分数对对象进行排序(不确定它们是否已经排序)。每个GKScore都有一个player属性,您应该可以对其进行比较。看看那个球员是否与你当地的球员相匹配。
