I have consumable In-App-Purchase product in my iTunes connect, and when I'm trying to buy it twice (on my iPhone), it tells me that I already bought it. But this is the whole point of consumables, that users can buy them over and over. Any suggestions?
This happens if you haven't marked the transaction for the original purchase as finished, which you should do in your - (void)paymentQueue:(SKPaymentQueue*)queue updatedTransactions:(NSArray*)transactions
method after you've successfully processed the purchase.
The method you need to call is [[SKPaymentQueue defaultQueue] finishTransaction:transaction]
.
