How do you keep track of total quantity from singular pack in-app purchase?

42 views Asked by At

I have a couple in-app purchase items for hints for my iOS game. One pack is $0.99 for 6 hints, so if a user purchases this item, how do I keep a record of how many hints they have in total (given they keep purchasing and using)? Could it be as simple as using Core Data?
