Hello, I made a game for android and now I am trying to make it work with iOS. I have been following the documentation on how to use SocialPlatforms.GameCenter but Since i am fairly new at this I am getting stuck. :frowning:

This is the Error I receive:

LeaderboardsController.cs(68,44): error CS1501: No overload for method ShowLeaderboardUI' takes 1’ arguments

In my code I am passing ShowLeaderboardUI only one argument - a constant string which is my leaderboardID. (below is the entire class)

using UnityEngine;
using System.Collections;
using UnityEngine.SocialPlatforms;
using UnityEngine.SocialPlatforms.GameCenter;

public class LeaderboardsController : MonoBehaviour
{

    public static LeaderboardsController instance;

    private const string LEADERBOARDS_SCORE = "MYIDFORLEADERBOARDHERE";

    void Awake()
    {
        MakeSingleton();
    }

    void Start()
    {
        //PlayGamesPlatform.Activate();

    }

    void OnLevelWasLoaded()
    {
        ReportScore(GameController.instance.GetHighscore());
    }

    void MakeSingleton()
    {
        if(instance != null)
        {
            Destroy(gameObject);
        }else
        {
            instance = this;
            DontDestroyOnLoad(gameObject);
        }
    }

    public void AuthenticateToGameCenter()
    {
        //you are logged in
        #if UNITY_IPHONE
            Social.localUser.Authenticate((bool success) => {
              if(success)
              {
                Debug.Log("Success");
              }
              else
              {
                Debug.Log("Failed");
              }
            });
          #endif
    }
    public void OpenLeaderboardsScore()
    {
      #if UNITY_IPHONE
        if (Social.localUser.authenticated) {
    			GameCenterPlatform.ShowLeaderboardUI (LEADERBOARDS_SCORE);
    		} else
    		{
    			Debug.Log("something went wrong");
    		}
        #endif
    }

    void ReportScore(int score)
    {
      #if UNITY_IPHONE
        if (Social.localUser.authenticated)
        {
            Social.ReportScore(score, LEADERBOARDS_SCORE, (bool success) => { });
        }
      #endif
    }
}

The Docs say to have a TimeScope. I am not really sure how to write one - is this required?

Please help, thank you very much in advance! :slight_smile:

You should add the scope of time through query is searching.
like this.

GameCenterPlatform.ShowLeaderboardUI(“ID”,TimeScope.AllTime);
