I made a sandbox iTunes user, bought an item. That worked but there were some issues in my code for displaying the item. So, I want to re-buy it to test again. Problem is, I can't clear my purchases. I signed out my sandbox user, deleted the app and re-installed it, changed itunes users a few times... the item still shows up as purchased.
I'm using MKStoreKit.
Any ideas?
Well, I figured it out. MKStoreKit saves purchased items to the keychain, which persists even if you change iTunes accounts or delete the app. Calling a quick [[MKStoreManager sharedManager] removeAllKeychainData]; reset things.
If you have your own domain, you often get email handling for free; for example, I have a go daddy account, and I can set a mail forwarding rule for unrecognised email accounts. This makes it very easy to create loads of test accounts without having to have a separate email account for each one.
