Purchasing one item multiple times in TInApppurchase in Delphi XE6

Question

I have developed an application with Delphi XE6 including inappPurchase, I have defined the product as 'Consumable' in itunesConnect, but after purchasing one item, it won't let me buy another one.

In my application user should be able to buy 'n' number of licenses, in PurchaseProduct Method just takes productID as parameter so I need to call this method multiple times.

I thought defining another Product like as 10-Licenses would be a good idea, but there is no relation between this two Products, and ConsumeProduct Method just takes a ProductID not the number of consumtion.

Since lack of resources about that, I appreciate if some one gives me some hints, or best practices.

p.s. Is storing the number of purchased products in application good idea?

Answer 1

I found the solution but I don't know if it is correct or not:

I consume the product just right after purchasing, and I locally get the track of bought items.
