How to use the game center on iOS 7 to create live matches?

Question

Do you guys know any tutorial or sample code that covers using Game Center on iOS 7 to create live matches?

All Apple code samples are from 2011 (!), And their documentation is incomplete and vague, and also talks about iOS 6. All the training materials I found on the Internet are for iOS 6, and they do not cover live matches. Obviously, Apple doesn't care about that.

Any suggestion?

Answer 1

Back when I was working on game center material, I used this example application developed by Apple for my links. I could no longer find it on my site, but it seems like some person posted it on github for you!

I'm not sure how much this has changed since iOS7, but I suggest this as a start
