We have two IAPs in our app that purchase Non-Renewing subscriptions.
- (void)paymentQueue:(SKPaymentQueue*)queue updatedTransactions:(NSArray*)transactions
is being called correctly and during:
- (void) CompleteTransaction:(SKPaymentTransaction*)tran
we are calling:
[[SKPaymentQueue defaultQueue] finishTransaction: tran];
We can successfully purchase either of the subscriptions once with our test account.
Yet when we try to repurchase the items, to test when you subscription expires, we get this AlertView:
"You've Already purchased this in-app purchase but it hasn't been downloaded"
We are in Xcode 4.2 on the iOS 5 sdk/iOS 4.1 deployment target.
UPDATE:
Looks like this is a bug in iOS 5.0.1 on the device.
I am able to re-purchase the IAP items on an iPod Touch running iOS 4.1. I can build the app for SDK 4.1, 4.3 or 5.0 and it still works. However, if I build the app for SDK 4.1, 4.3 or 5.0 and try to run on my iOS 5.0.1 device, it never works.
This is is error from the iOS 5.0.1 device:
Failure:Error Domain=SKErrorDomain Code=2 "Cannot connect to iTunes Store" UserInfo=0x1f90f0 {NSLocalizedDescription=Cannot connect to iTunes Store}
Apple confirmed this bug. I submitted a bug report and had a back and forth with Apple Engineer.
