title: How to add iAP with iAPHelper and CocoaPods?
body: <p>I've tried to add in app purchase to my app to provide users the option to buy the app without iAd. So I searched for a good cocoa pod because the implementation of in app purchase is very heavy. Cause iaphelper seems to be the best I've tried to implement it in my project like this but as you see that doesn't work that well. Anybody an idea how to make this work?</p>
