game-center

So I am sending scores to the GC leaderboards, I receive no errors and the scores apprently send but I still see no scores listed in the leaderboards! The leaderboard itself is listed in Game Center there are just no scores. According to a Google search and a question on here this could be resolved by attempting to log scores with more than one account. I have tried on three different accounts now both in Simulator (iOS5) and on my iPhone; none of them show any errors when submitting the scores. The code that sends the score is here: - (void)reportScore:(NSString *)identifier score:(int

I am working on an education application but I want to implement a leader board and achievement feature to it. So I come up with Game Center. My question is, this application is now in the education category and I don't want to move it to Game category. Will it be rejected in the application review because I integrate Game Center with a non-game application? If your app is not a "Game" then it will not be allowed on the App Store if it integrates Game Center. See here... http://abitofcode.com/2012/05/so-what-happened-to-sketchshare/ This app was removed from the app store (having previously

I am working on a simple turn-based word game, and I'm having a difficult time figuring out how invitations are working. When user A invites user B to a game, I want user B to be able to see this game in my custom match interface (ie a screen where all of user B's games are listed). Things are fine if user B clicks on the notification when he is invited to a game, but I still want the game to be visible through my own interface if user B just navigates to the app on his own. Whenever this match interface screen appears, I am using [GKTurnBasedMatch loadMatchesWithCompletionHandler:] to get all

Does GameKit allow you to invite a specific Game Center friend to a match, programmatically, i.e. without presenting the GC ViewController? The following handleInviteFromGameCenter documentation seems to imply that you can populate GKMatchRequest.playersToInvite and use it with [GKTurnBasedMatch findMatchForRequest]: When your delegate receives this message, your application should create a new GKMatchRequest object and assign the playersToInvite parameter to the match request’s playersToInvite property. Then, your application can either call the GKTurnBasedMatch class method

This question already has an answer here: Unable to sign in Sandbox gamecenter on iOS 7 4 answers The problem is strange. My system version is IOS7. Everything goes fine on ios7 simulator. However, when I try authenticate on my iphone, the error in the callback block is always "GkErrorCanceled: the requested operation has been canceled or disabled by the user". Even if I've already logged in game center, the error still pops. I tried google the problem, and find someone on stackoverflow had conquered the issue: iPhone Simulator 6.0 not able to connect to gamecenter in sandbox mode . I tried

Right now I am working on a Black Jack game for iOS and would like to have a leader board that shows which players currently have the most "money". So if they get a high score and then lose "money" it would update their high score to match the users current amount of money, which would be less than before. Is there any way to do this with Game Center? Things have changed since iOS7. Now you can change the "Score Submission Type" to "Most Recent Score" instead of "Best Score". This is an option in iTunes Connect when you create a new leaderboard. Sorry to disappoint you but Game Center only

I'm making a turn-based game, using the Game Center Turn-Based Gaming functionality. I'm using the simulator and my iPhone to test notifications of turn events. The results are very inconsistent. About 75% of the time when I make a move on the simulator and pass the turn I don't get any notifications on my iPhone. It seems that this function doesn't get called: handleTurnEventForMatch:didBecomeActive: I set the GKEventHandlerDelegate in the code that authenticates the local user and it seems to be set correctly. The fact that I get notifications once in a while suggests that this isn't where
