GameCenter Achievements for a Game!

I have a game in which you earn points. I want to make GameCenter achievements if you, for example, get 100 points in the game. How would I make my app game do the following:

  1. Ask the user to access GameCenter/Log in to GameCenter when the app is first opened after download.
  2. Post the achievements in the GameCenter app, and make it a notification.
  3. Access the GameCenter achievements so that the player can look at his achievements from my game.

Thanks,

We use the Prime31 GameCenter plugin for this.

Ah, okay. Thanks :slight_smile:
