It depends on where the user is in the app's flow. In iOS there is no simple call to retrieve the current first responder (without private APIs) - see this dated SO thread for discussion: https://stackoverflow.com/questions/5029267/is-there-any-way-of-asking-an-ios-view-which-of-its-children-has-first-responder

Docs says this about that, otherwise:

"The first responder is typically the view in a window that an app deems best suited for handling an event."

Why do you need this?
