To realize a custom keyboard i tried this example from github:
CustomKeyboardDemo (sorry, it's not allowed for me to add link).
It worked fine if the custom renderer inheritate from PageRenderer.
But i have to work with ViewRenderer.
In my iOS project I created a renderer which inharitate from a ViewRenderer and used LayoutSubviews() instead of DidLayoutLoad().
Now the view works fine, but the keyboard doesn't appear as before, when the PageRederer was used.
What's going wrong there ?
