Game Center Question

[michaelmaitland]

Just wondering, because I've never used Game Center in one of my apps before. What did use use for Leaderboard Reference Name, Leaderboard ID. Im kinda having trouble understanding how your code links to GameCenter. Did you have to write in the code that you were using Integer Format, Score Limit, etc.

The first step is to setup all Game Center stuff for your app on iTunes Connect. You must create an app on iTunes Connect before.
By the way - this app is available on App Store, and all the Game Center stuff works well. So you may use my code as example of ready and working solution for your needs.
