Chapter 23: Code not working

[versluis]

I've encountered a slight glitch in trying to implement your In App Purchase code. It doesn't seem to work anymore in Xcode 4.5 (even when deployed to an iOS 5 device).

First there's a problem with the keyboard. When I touch a key on my "real" keyboard I get the following log message. I can type on the on-screen keyboard though:

Next, long-pressing the cow (which is very cute) brings up the Buy a Baa button, but no purchase is performed. It only ever brings up the "adults" audio sample, accompanied by this log entry:

Just thought I'd let you know for future releases.

You probably want to use the code with your own app and in-app purchase rather than relying on things from my personal account. The baa was re-created as part of the iOS 6 update:
#define PRODUCT_ID @"com.sadun.moo.baaa"

As for items stored in your personal user dictionary, I have no control over that. (Perhaps you're confusing Core Data store with App Store?)

Thanks for getting back so quickly, baaa indeed brings up the purchase window. I still get a "transaction not completed" error at the end on the simulator. On a real device (iPod Touch 4) the app hangs after the purchase window appears (i.e. I can't press either button).

The keyboard is a weird one, I'm as confused as you are about the reference to Core Data in the log entry. If I run the app in the simulator it does not accept keyboard entries from my real Mac keyboard (like apps usually do). As soon as I touch a "real" key on my keyboard, that log entry comes up. If I just use the virtual keyboard it doesn't happen. Crazy!
