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.

My problem arises when I add a SKPayment to the SKPaymentQueue. After I add the product to the queue, in the paymentQueue:updatedTransactions method the transactions always have the state SKPaymentTransactionStateFailed.

I NSLog the “transaction.error” and this is what it returns: Error
Domain=SKErrorDomain Code=0 UserInfo=0x165000 “Cannot connect to
iTunes Store”

I have logged out of the Store in the Settings app, but after trying to purchase a product in my app it never asks me to log in with my test account. It just fails with the above error.

I assume you’ve done the standard sanity checks: double-checking your code, confirming your product IDs, comparing your code to the In-App Purchase Programming Guide, etc.

This may be ridiculous, but — if you’re certain your code is correct — do a hard reset (full wipe) of your iPod (Settings => General => Reset => Erase All Content and Settings). I puzzled over this exact problem for hours — it turned out my code was correct and the hard reset was the solution.
