Question

I am using in-app purchase in my application. Everything is working fine.
User can buy, restore transaction properly.

I have 1 issue in restore feature:

How do I implement – user can’t restore without buying any item, because when user click on restore button without buying any item then it goes for restoring and app is blocked.

Answer 1

No need to implement the web-service just few lines of codes solve the issue –

- (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {
int totalNumberOfPurchaseToBeRestored = queue.transactions.count;
if (totalNumberOfPurchaseToBeRestored == 0)
{
    //No item found for Restore"
}
else
{
        // Restore items
}

}
