In-app purchase iOS manager

Has anyone implemented the in-app purchase option in the iOS app? Apple requires me to implement this option to authorize the app in App Store.
Any ideas?

You shouldn't need to, unless you want your users to purchase something directly from the app.

I have 3 apps based on iOS Manager in the App Store, published without problem, but I'm trying to publish a fourth app and I've been several days on this and Apple insists that in-app purchases must be implemented. Here's what the app review team says

Guideline 3.1.1 - Business - Payments - In-App Purchase
We still noticed that your app includes or accesses paid digital content, services, or functionality by means other than in-app purchase, which is not appropriate for the App Store. Specifically:

• Your app accesses digital content purchased outside the app, such as digital monitoring of vehicles, but that content isn't available to purchase using in-app purchase.

Sometimes Apple is difficult to deal with.

I fully agree

I sent a new app for review to Apple and I got this information back, which I will share with you all
