game-center

I have used [[GKTurnBasedEventHandler sharedTurnBasedEventHandler] setDelegate:self]; but I am not receiving delegate calls. This was working at one point, and I can't figure out for the life of me what has changed. The app is properly badged (on the device home screen, it shows a badge with the number of games where it is my turn). Furthermore, using GKTurnBasedMatch loadMatchesWithCompletionHandler: is able to detect when it is the player's turn (or not). In fact, in every other conceivable way, GameCenter seems to be working perfectly. I can even send (and accept) challenges, but again, the

I want to login to my app via GameCenter Login API. Is it possible ? Is Apple game Center login API public? If you're using iOS 6, see the documentation for GKLocalPlayer. You'll see that you assign a block to the 'authenticateHandler' property of localPlayer. When you assign it, if the player isn't already logged into Game Center, one of the arguments to the block (UIViewController *viewController) gets filled in with the address of a view controller that will present the regular Apple Game Center login screen. After you get that address you do presentViewController:viewController and the

With an internet connection Everything works flawlessly. There is no memory problem leading to crash. With no internet connection The app proceeds to the menu screen, where it eventually crashes because it is out of memory. I have concluded that the problem lies in the following line of code Social.localUser.Authenticate When I comment out the above line, the memory problem goes away when there is no internet connection. Here is my relevant code void Start () { Social.localUser.Authenticate(ProcessAuthentication); } public void ProcessAuthentication(bool success) { if(success) Debug.Log (

How can I use Game Center or the GameKit Framework with a Sprite Kit Xcode template? In Sprite kit, it uses Scenes; but normally to view the leaderboards for example you need to "presentModalViewController" but that is not possible in SKView. And how can I authenticate the player and all that other fun stuff in iOS 6. Thanks in advance! you can authenticate like this [[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) { if (error == nil) { static_setEnable( true ); NSLog(@" Authenticate local player complete"); } else { static_setEnable( false ); NSLog(@

I've been stumped on this for quite a long time. I understand how to unlock an achievement in Game Center and I even got a whole messaging system working. But I can't figure out how to check if an achievement has already been unlocked :( Apparently this doesn't work: GKAchievement *achievement = [[GKachievement alloc] initWithIdentifier:ident] autorelease]; NSLog(@"%i",achievement.completed); It always traces "0". Unlocking an achievement does work: GKAchievement *achievement = [[GKachievement alloc] initWithIdentifier:ident] autorelease]; achievement.percentComplete = 100; So it's not that I
