Protocol

UITextInputDelegate

The text input delegate acts as an intermediary between a document and the text input system, conveying notifications of pending or transpired changes in text and selection in the document.

Overview

UIKit provides a private text input delegate, which it assigns at runtime to the inputDelegate property of the object whose class adopts the UITextInput protocol.
