Q:

Implementing Achievements in iOS App without Game Center

Is there anyway possible to implement challenges and achievements in an app without using Game Center. The current app that I'm working on is not a game, but has challenges and achievements based on photo users submit. For example if a user uploads a photo of their pet, they get 50 points for  submitting that picture. 

A:

You can use that, I create a simple class for iOS game center in github
