Creating an option type menu in iOS

This is what I'm talking about, just to hide half of the view in question:

I searched the Internet for hours, but it seems I am missing some kind of keyword. I searched: iOS menu, iOS overlay menu, iOS options menu, iOS sharing menu (as it looked like the old one), iOS Called Menu and options for all of these. It would be very helpful if someone could tell me the name of this type of menu or explain how to create it.
