/**
 * This document declares the relevant components to implement the input area.
 * The input area includes the emoticon view input area (TUIFaceView+TUIMoreView), the "more" functional area (TUIMoreView) and the text input area
 * (TUIInputBar). This file contains the TUIInputControllerDelegate protocol and the TInputController class. In the input bar (TUIInputBar), button response
 * callbacks for expressions, voices, and more views are provided. In this class, the InputBar is actually combined with the above three views to realize the
 * display and switching logic of each view.
