Can I add ionic to an existing iOS App?

I have an iOS app in Objective C.

I need to develop some additional screens for it.

Can I develop them with ionic ?

Do you understand what I want ? I want to add ionic to an existing iOS App.

You shouldn’t, unless you plan to mix native views with a web view containing a PhoneGap app, which would just be weird and hacky and a terrible idea. If you don’t already understand how to manually embed a PhoneGap web view, then I’d say don’t even attempt it. You’d still need a custom PhoneGap plugin so that the native pieces and the PhoneGap/ionic pieces could coordinate.
