"This game is not recognized by Game Center" error

Question

I'm struggling to get past the first stage of getting Game Center integration to work. I've got this far:

I've created a new, clean app, added the GameKit headers and the basic authenticateWithCompletionHandler: method in the app delegate.

Starting the app in the simulator brings up the login dialogue.

If I create a NEW account via the login dialogue, then that user gets authenticated and the app loads successfully.

If I attempt to log in with that account a second time, OR use an account that I've created using the simulator's Game Center app, the login is rejected with a "this game is not recognized by Game Center" error.

Resetting the simulator and reinstalling via XCode has no effect. The app is set up for Game Center via iTunes Connect, and the bundle identifiers are all correct.

Can anyone suggest where I'm going wrong here?

Answer 1

Check Your app is Game Center enabled in iTunes. Also check the correct bundle Identifier you are given in you project
