game-center

When using the authenticateHandler in iOS 6, game center won't present the login view if the user cancels it. I realize game center will auto lockout an app after 3 cancel attempts, but I'm talking about just 2 attempts. If they cancel the login, they have to leave the app and come back before game center will present the login even through the authenticateHandler is getting set again. Any ideas on how to handle this case in iOS 6? It works fine when using the older authenticateWithCompletionHandler method: #if __IPHONE_OS_VERSION_MIN_REQUIRED >= __IPHONE_6_0 GKLocalPlayer.localPlayer

I'm thinking of adding a feature to my iOS game to allow players to create their own game levels, share them with other players, rate them, etc. There'd be a public repository of user-created levels, sortable by creation date, rating, difficulty, or other criteria. This kind of functionality would necessitate a third-party server. I was thinking I'd create a RESTful API using Sinatra and run it on Heroku. My question is: what would be the best way to authenticate requests to this API? I would prefer not to require players to create a username and password. I'd like to just use Game Center's ID

Has anyone noticed any changes to turn based match notifications since updating to iOS8.3? In my app when I call endTurnWithNextParticipants, prior to the upgrade, this was resulting in a notification being sent to the opponent which would trigger a receivedTurnEventForMatch being invoked on their device but this no longer is the case. When the opponent terminates the app and restarts it they can see it is their turn so the match in game centre was correctly updated with the order of participation but this doesn't seem to take effect dynamically any more. Anybody else see this? I'm hoping it's

Is there any one who knows how to integrate game center in Cocos2d. Please tell me steps so i can integrate that in my Game. UPDATE: I created my own Helper Class that works with all kind of Apps (also Cocos2D 1 & 2+) https://github.com/alexblunck/ABGameKitHelper Hi I suggest you use GKHelper Class from Steffen Itterheim! I uploaded the GKHelper.h / GKHelper.m for you: http://www.cl.ly/7ReW Then follow these instructions: //0.0 Add GameKit Framework to Project (Ask If you don't know how to do this ;) ) //0. Change "[window addSubview: viewController.view];" in the AppDelegate.m to: //Do this

I have a problem with logging a user to the Game Center. I first present the login dialog right after the application finishes loading. If the user cancels the dialog, I want to give him the option to change his mind by providing a login button in my main menu. However, on iPads with iOS7, the button doesn't do anything - the Game Center dialog doesn't get shown (it works correctly on iOS6). Instead, I immediately get the error "The requested operation has been cancelled or disabled by the user." Same code is called on application launch and on the button tap. It uses the

Since iOS 7 I no longer get the prompt from game center to ask me to log in sandbox mode when I open my application. I searched for a while and never saw any known issues about this and there are no patch notes that says anything about sandbox mode changing. Has anyone encountered this problem? If you've cancelled game center sign in enough times, the OS disables game center for that game. Prior to iOS7, you could manually sign in again using the game center app, and when you launch your game again it would sign in. However, in iOS7, it appears that when the OS disables game center for your
