Gamecenter leaderboards?

Hello. I know that using GameCenter features in a unity project is a complex subject but I am wondering what do I do first if I want to integrate GameCenter leaderboards into my unity iOS game(does anyone have any links to any good tutorials)?

The first thing is either:

  1. License Prime31s plugin for GC
    or 2. Write a binding layer in C / ObjC which you then can bind against from Unity (mobile plugin, available in any mobile license) - thats what Prime31s plugin would do for you

generally if you don’t pay for others work you will require quite some work on the native code side with only very little code in C# / JS / Boo
