What types of payments are strictly forbidden in IOS, I've heard that everyone should use the in-app purchase ... In my case I want to release a free version with limited functionality for the user and if he likes it, he buys the version complete using credit card, I want to add still the possibility of the user to buy items that will be delivered to his house, something like, t-shirts, water bottles etc. For such cases am I required to use the in-app purchase? Or can I receive the card data and process it on a payment gateway?
