如何在iOS中顯示排行榜集合

Question

我試圖讓這個工作在昨晚完成，但它不會。誰能幫忙？

我用下面的代碼來顯示排行榜： gameCenterViewController.leaderboardIdentifier = leaderboardId

這正常排行榜工作正常，但無法加載任何排行榜套，當我使用leaderboardSetId。你能直接鏈接到排行榜集，如果是的話，你如何做到這一點？

謝謝。

Answer 1

確保您已認證本地播放器和在iTunes Connect中設置的排行榜，您需要report your scores to GameCenter以確保您使用64位Int。 現在你可以添加這顯示了領先的本土球員：

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) 
}

請你參考下代碼與跨驗證配置。

希望這會幫助你。

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) 
} 

}

也請做檢查從後端的排行榜配置。
