Hi,

I'm surprised that the SKPaymentTransaction object doesn't include the productIdentifier of the product that was being purchased.

I need this information in my transaction observer so I can record which product was purchased and configure my app accordingly.

I guess I could keep track of this by recording the last product a user tried to purchase, but that seems error-prone; it doesn't account for restoring transactions on a new device, or the possibility that the transaction observer might be called at a time later than expected, or that two purchases might overlap.

Is there a way to obtain the productIdentifier from the transaction?

Thanks,

Frank

It does.

transaction.payment.productIdentifier

-(void) paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
   for(SKPaymentTransaction *transaction in transactions){
        switch (transaction.transactionState){
            case SKPaymentTransactionStatePurchased:
                if([myArrayOfProductIdentifiers containsObject:transaction.payment.productIdentifier]){
                 ////
                }

Thanks. The documentation is kind of broken here. I notice now that payment is a property of type SKPayment, but it's not linked in the documentation. You have to manually type it in to the search bar to find it.
