Question

我试图让这一切都在昨晚完成，但它不会。有人可以帮忙吗？

我使用以下代码显示排行榜： gameCenterViewController.leaderboardIdentifier = leaderboardId

这适用于普通排行榜，但在使用leaderboardSetId时无法加载任何排行榜集。你能直接链接到排行榜集，如果是这样，你怎么做？

感谢。

请参考以下代码并交叉验证您的配置。

希望这会对你有所帮助。

import GameKit
class YourViewController: UIViewController, GKGameCenterControllerDelegate {

var gcEnabled = Bool() // Stores if the user has Game Center enabled
var gcDefaultLeaderBoard = String() // Stores the default leaderboardID

override func viewDidLoad() {
    super.viewDidLoad()

 self.authenticateLocalPlayer()

}

func authenticateLocalPlayer()
{
    let localPlayer: GKLocalPlayer = GKLocalPlayer.localPlayer()

    localPlayer.authenticateHandler = {(ViewController, error) -> Void in
        if((ViewController) != nil) {

            // 1 Show login if player is not logged in

            self.presentViewController(ViewController!, animated: true, completion: nil)

        } else if (localPlayer.authenticated) {

            // 2 Player is already euthenticated & logged in, load game center

            self.gcEnabled = true

            // Get the default leaderboard ID
            localPlayer.loadDefaultLeaderboardIdentifierWithCompletionHandler({ (leaderboardIdentifer: String?, error: NSError?) -> Void in
                if error != nil {
                    print(error)
                } else {
                    self.gcDefaultLeaderBoard = leaderboardIdentifer!
                }
            })


        } else {
            // 3 Game center is not enabled on the users device
            self.gcEnabled = false
            print("Local player could not be authenticated, disabling game center")
            print(error)
        }

    }
}


    @IBAction func clickToLeaderBoard(sender: UIButton) {

        let gcVC: GKGameCenterViewController = GKGameCenterViewController()
        gcVC.gameCenterDelegate = self
        gcVC.viewState = GKGameCenterViewControllerState.Leaderboards
        gcVC.leaderboardIdentifier = "YourLeaderboardId"
        self.presentViewController(gcVC, animated: true, completion: nil)

    }

func saveScoreOnGameCenter()
{
    let leaderboardID = "YourLeaderboardId"
    let sScore = GKScore(leaderboardIdentifier: leaderboardID)
    sScore.value = Int64(10)

    GKScore.reportScores([sScore], withCompletionHandler: { (error: NSError?) -> Void in
        if error != nil {
            print(error!.localizedDescription)
        } else {
            print("Score submitted")

        }
    })
}

func gameCenterViewControllerDidFinish(gcViewController: GKGameCenterViewController)
{
    self.dismissViewControllerAnimated(true, completion: nil)
}

}

另请检查后端的排行榜配置。

确保您已对iTunes Connect中设置的本地播放器和排行榜进行身份验证后，您需要report your scores to GameCenter确保使用64位Int。现在您可以添加此项以显示本地播放器的排行榜：

func showGKGameCenterViewController(_ viewController: UIViewController) {
    if gameCenterIsDisabled {
      print("Local player is not authenticated")
    }
    let gameCenterViewController = GKGameCenterViewController()
    gameCenterViewController.delegate = self
    gameCenterViewController.viewState = GKGameCenterViewControllerState.default

    viewController.presentViewController(gameCenterViewController, animated: true, completion: nil)
}
