I have an e-commerce App based on WebKit. I know apple will reject the app because it contains payments and we don't use there in app purchase. so, my question is: is there any way to integrate in app purchase with the WebKit. for example, once the user clicks on "buy" button, we may terminate the webView and presenting a view controller with payment details.
It looks like You don’t need in app purchase if you are offering consulting services.
3.1.3(d) Person-to-Person Services: If your app enables the purchase of real-time person-to-person services between two individuals (for example tutoring students, medical consultations, real estate tours, or fitness training), you may use purchase methods other than in-app purchase to collect those payments. One-to-few and one-to-many real-time services must use in-app purchase.
