Swift：检索 LocalPlayer GC 分数

Question

下面是我获取本地玩家游戏中心分数的代码。

if (GKLocalPlayer.localPlayer().authenticated) {
    GKLeaderboard.loadLeaderboardsWithCompletionHandler { objects, error in
        if let e = error {
            print(e)
        } else {
            let leaderboards = objects! as [GKLeaderboard]
            print(leaderboards)
            for leaderboard in leaderboards {
                print(leaderboard)
                print(leaderboard.localPlayerScore) // This prints nil
            }
        }
    }
}

我 nil 获得 print(leaderboard.localPlayerScore) ，虽然我确信本地玩家已将分数保存在此排行榜上。我错过了什么吗？

你得打电话

leaderboard.loadScoresWithCompletionHandler() { scores, error in
    if error == nil {
          print(leaderboard.localPlayerScore)
    }
}
