I am trying to setup in-app purchases for my Mac app. Purchasing products works fine but I was not able to get [[SKPaymentQueue defaultQueue] restoreCompletedTransactions] working.
A transaction observer is set (otherwise purchasing would not work) and use [[SKPaymentQueue defaultQueue] restoreCompletedTransactions] to restore all previous purchases.
StoreKit should now use paymentQueue:updatedTransactions: to restore the transactions and paymentQueueRestoreCompletedTransactionsFinished: or paymentQueue:restoreCompletedTransactionsFailedWithError: to report success or failure. But non of these methods are called. There is absolutely no response.
If I use [[SKPaymentQueue defaultQueue] restoreCompletedTransactions] I get the following output:
Ignoring restoreCompletedTransactions because already restoring transactions
There a lot of discussions where restoreCompletedTransactions returns an empty result. But in my case there is simply no result.
How can I find out what is going wrong?
