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