Apple App Store

Hello. When drawing a design for a mobile application for iOS, a question arose.
What payment methods can be connected inside the application?
That is, the application will have a paid subscription. Accordingly, what methods generally exist under iOS?

Answer 1

Payment methods in the AppStore -
As a designer, you don't need these methods at all. It's up to you to draw the "Paid Subscription" buttons or any other in-app purchases. In-app purchases are implemented by the application developer.
