在游戏IOS中免费进行应用内付款

Question

In my game, I want to mix free in app payment and 0.99$ in app payment.

I mean to continue to level 2, user needs to pay 0.99$ using in app payment. But level 3 and 4 are free of charge and level 5 costs 0.99$.

I need to know from IOS server or save in database if user gets level 3 or 4 to restore the game if it was uninstalled.

I know I can get purchased items from IOS server when they are paid, but I don't know if it's possible to get an item that was purchased for free or even if it's possible to purchase an item for free using in app payment.

Maybe I need to get some user info and save to my database to track its state.

Thanks in advance for your help.

Answer 1

Consumable an Non-Consumable In-App Purchase can't be Free. You have to choice a price (0.99$ minimum)

I think you have to make one IAP with levels 2, 3 and 4. And an other one with levels 5 (and perhaps 6 and 7).
