iPhone Store Kit “Cannot connect to iTunes Store”

Question

I am working on adding In-App purchases to my app.

I am able to receive the productsRequest:didReceiveResponse method, and receive the array of products

Answer 1

I was getting SKPaymentTransactionStateFailed error code 0 "Cannot connect to iTunes Store" and thanks to thomax for this answer my problem is solved. Turns out you MUST enter a build number under Targets->Summary.

I spent the last 24 hours resetting my phone, screwing with iTunes connect, and doing just about everything i could think of before i stumbled upon this solution.
