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

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

I am trying to write an app that exchanges data with other iPhones running the app through the Game Kit framework. The iPhones discover each other and connect fine, but the problems happens when I send the data. I know the iPhones are connected properly because when I serialize an NSString and send it through the connection it comes out on the other end fine. But when I try to archive a larger object (using NSKeyedArchiver) I get the error message "AGPSessionBroadcast failed (801c0001)". I am assuming this is because the data I am sending is too large (my files are about 500k in size, Apple
