HI

i want to connect to Game Center with my game , i've done all coding i can see the game center open and works fine but when i pass my high score to game center in simulator it wont show the high score , not sure whats wrong :

 GKScore score = new GKScore("hsid") ;

 score.value = Highscore;

 Guide.showleaderboard() ; 

thanks for helping

It won't show any scores until at least 2 different gamecenter accounts submit a score.  Same thing drove me nuts.  Create a 2nd account and try submitting.

Thanks tschacht ,  work pretty well . 

Hi,

I have created two accounts on GameCenter and I have submitted my scores, however, I don't' see any records. I am using the emulator. Here is my code:

			GKScore gkscore = new GKScore();
			gkscore.Value = 1000;

My app has a single leader board only, so there are no categories. My user is logged into the GameCenter before the game begins. Is my code correct?

Here us the complete GC code that I use for saving scores:

When game starts, I attempt to sign the gamer in with:

Guide.IsVisible = true;
Guide.ShowSignIn(1, true);

Then, I call the following SaveScoreToIosGameCenter() function when I want to submit the scores:

		public static bool IsSignedIntoGameCenter() {
			if ( ( Gamer.SignedInGamers.Count > 0 ) && ( Gamer.SignedInGamers[0].IsSignedInToLive ) ) {
				return true;
			}
			return false;
		}
		
		public static SignedInGamer GetSignedInGamer() {
			if (IsSignedIntoGameCenter()) {
				return Gamer.SignedInGamers[0];
			}
			return null;
		}
		
		public static void SaveScoreToIosGameCenter(String category, long score) {
		
			if (IsSignedIntoGameCenter()) 
			{
					var gamer = GetSignedInGamer();
					if (gamer != null) {
						gamer.UpdateScore(category, score);
					}
			}
}

Hi,

Thanks for the code and I really appreciate your help.

For my game, I created a single leader board. Its ID is com.jmawebtechnologies.spaceracermyleaderboard. Is that what I use for category? If not, do I leave category as an empty string? My leader board has no category, so that's why I'm asking.

Hi

Did you setup leaderboard in "Manage Game Center" section in itunes connect ? 

 The “Leaderboard Reference Name” is an internal name that you must provide for each leaderboard. I Named mine “High Scores” . The “Leaderboard ID” is a unique alphanumeric identifier that you create for this leaderboard. I chose “hsid” .  i used this leaderboard ID later in GKScore to identity our leaderboard . 

GKScore score = new GKScore("hsid") ;

use below code to send the data to Game Center  :

score.ReportScore (delegate (NSError error)
			    {
				if (error != null)
				{		
				Console.WriteLine(error.LocalizedDescription);		
				}
				else
				{
				Console.WriteLine("Sent") ; 				
				}
