Several days later, you can download it in the app store.

So can you give us some simple step by step hints what we have to do to add GameCenter easily?

For Game Center, there is a class to use.
In the iOS sample, there is project named GKTappler, take the class file from that project,and add into your project.

The GameCenterManager class is very easy to use. Then your game has Game Center.

Found a step by step tutorial here:

It requires quite some setup!

@halley : Do you fancy writing a guide on how a regular T2 user can prepare their app to use the Game Center? I understand if you're pressed for time, but if you find yourself with a spare weekend I think your guide will pretty much educate around a thousand AppGameKit users - that's a substantial block of Karma gain

I would like to do it in the spare time Maybe tonight.Then I post a thread here.

Thanks for the links @bjadams. Great!

Halley Check these links, maybe they can help you for your tutorial....
