I have an application that is like a guide that has information. I want it so if a user finds something on a page they have never been before i want them to get an Achievement. Maybe even a leader board to add points for users to see who discovered the most?

I'm a little confused... Are you asking how to do this? A tutorial? What's the question? -tM

Yes a question on how to implement it

Ah, well Apple's docs we're my best resource when learning GameKit. http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/GameKit_Guide/Introduction/Introduction.html -tM

If I was to approach this I would create a singleton that looks after the achievements and scores/leaderboards. The singleton would have a method that would be fired from the plugin/screen you want, this will involve many if statements if the screens are reused, for each of the achievements. It will probably be quite simple Scores on the other hand will be a bit more difficult as the total will be running. I would link the points to the achievements. So it would have a stored variable thatw ould be increased everytime an achievment is achieved. Save the new total then post the score

Could someone make an implementation guide for this?

This is something completely custom there is no guide google gamekit tutorial and learn to use it

Thanks
