UITextInput is an iOS protocol that defines behaviors for interacting with and responding to text selection, autocorrection, and other text input events.

UITextInput is an iOS () protocol that defines behaviors for interacting with and responding to text selection, autocorrection, and other user text input events. It allows conforming classes to respond to dictation (on iOS 5.1+), modify selected text, position the selection UI elements, etc. UITextField () and UITextView () are the two most commonly used classes that conform to the protocol.

For more information, please see the Apple Documentation for UITextInput.
