Adding in app purchases to an Open Feint powered game

Question

I am developing a game with cocos2d-iphone and I am going to add in app purchases. AFAIK my options are Open Feint X and MKStoreKit.

I still don't get what's the benefit of using Open Feint over MKStoreKit. Why would someone pick Open Feint?

Answer 1

I ended up adding some logic to MKStoreKit. You can get the code from my fork.

Answer 2

Why would someone use any 3rd party library over Apple's?

I think the question is moot because OpenFeint added IAP as a service to their existing developers. Meaning developers who use OF primarily as a social platform. And anyone who likes to use an all-in-one solution, from FB, Twitter via Game Center right down to IAP. From what I understand MKStoreKit is just an IAP wrapper with no other features.
