In this section, I'd like to go ahead and teach you how to implement a multi-line text input component for our CommentsController page. Another issue we have to fix is the input area being rendered underneath the bottom home indicator bar. I'd like tackle the implementation of this feature by first showing you how to refactor our input accessory view into a separate class <b>CommentInputAccessoryView</b>.
Once we have our code refactored out, it'll make our task of implementing our multi-line input much easier. This is because having our code isolated into a different component makes the project much easier to understand and navigate.
