I just read this tutorial: http://kwiksher.com/tutorials/IAP/01.InAppPurchase_en.html
My main menu shows 10 pages (buttons): 3 free and 7 locked with padlock icons.
My question is: Once the user purchase in 1 pay the seven pages, how do I remove the padlocks icons or show another menu with all pages unlocked?
It needs external codes. Kwik3 saves a text file if a product is purchased. It is product..”.txt” in app directory. The codes to check the text file exists or not and then to remove the padlocks or show another menu.
