paymentQueueRestoreCompletedTransactionsFinished: is returning an empty queue when it should have transactions in it

This is my first time using Store Kit and everything has gone great up until I attempt to restore purchases. I've seen several other posts on stack overflow about similar issues but I've not found a solution that works for me.

I have a button in my app that calls [[SKPaymentQueue defaultQueue] restoreCompletedTransactions]. This in turn triggers the SKPaymentTransactionObserver method paymentQueueRestoreCompletedTransactionsFinished:. The problem is that paymentQueueRestoreCompletedTransactionsFinished: has zero transactions in the returned queue.

If I then attempt to make the purchase I am notified that I have already made the purchase. This tells me that the store knows that my test Apple ID has successfully made the purchase on a previous attempt. Why then does paymentQueueRestoreCompletedTransactionsFinished: return an empty transactions collection on it's queue?

There has been some mention of the sandbox behaving erratically but I need to see this working before I go live to the AppStore.

Any ideas? Am I missing something?

Thanks in advance.

Solution

  • Are you handling the transactions in -paymentQueue:updatedTransactions:? This callback gets your restored transactions before the paymentQueueRestoreCompletedTransactionsFinished: callback.

    You should do your restore processing and handling inside -paymentQueue:updatedTransactions:.
