Q:

Is showing the payment pages using Webview solves the App-store's In-App Purchase issue?

I got a new message from Appstore for my new app submission:
Guideline 3.1.1 - Business - Payments - In-App Purchase

We noticed that your app or its metadata enables the purchase of content, services, or functionality in the app by means other than the in-app purchase API, which is not appropriate for the App Store.

My app has a payment feature and I have implemented it using stripe. 
The payment feature is implemented on sign up, free trial and manage subscription pages. Currently, I have implemented all these features in the app itself. I have website links for these pages and I can show these pages using a webview with the website links. If I do like that, is AppStore approve my app? I have also removed the Stripe.net NuGet package.

A:

If you offer digital goods & services within your app, you must use in-app purchases and give Apple their 30% cut.
You cannot use any other method, no matter which technology (webview, link, etc.) or provider (Stripe, PayPal etc.) you are using.
If you offer non-digital goods & services (i.e. taxi ride, physical books, etc.), you can use any payment for you seem fit and cannot (!) use in-app purchases.
