I added a Barcode Scanner and a share function in my webviewer app and they still dont accept the app.
APPLE:
Your app provides a limited user experience as it is not sufficiently different from a mobile browsing experience. As such, the experience it provides is similar to the general experience of using Safari. Including iOS features such as push notifications, Core Location, and sharing do not provide a robust enough experience to be appropriate for the App Store.
Next Steps
To resolve this issue, please revise your app to provide a more robust user experience by including additional native iOS functionality.
