It is not a programming question. Just a clarification on the in app purchase feature in iOS.
I am planning to have an App with premium content. My App can be used only when user authenticates with credentials. Is it possible for me to provide premium content (paid content) only based on the authentication. I will need the user to make a payment through another web App.
By this only when a user has purchased premium content through another app will have access to certain part of the content. Other users will have access to non premium content.
Will apple allow this? Is any app in app store that works this way?
Look at this question it can help
Purchase outside the store, apple conditions, HTML 5 applications
