[Feature] subclassing the UITableViewController to simplify content positioning and sizing.

[royhsu]

According to the Docs, UIViewController has to deal with content covered by the keyboard manually. It's better to make UITableViewController does this trivial tasks for us.

Adjusting your content typically involves temporarily resizing one or more views and positioning them so that the text object remains visible. The simplest way to manage text objects with the keyboard is to embed them inside a UIScrollView object or one of its subclasses, like UITableView. Note that UITableViewController automatically resizes and repositions its table view when there is inline editing of text fields (to learn more, see View Controllers and Navigation-Based Apps).

Solution 1

Make CollectionViewLayout as the Controller-level thing.
And also make ListViewLayout subclass the UITableViewController

Solution 2

Create UIKeyboardController that subclasses the UITableViewController as the content wrapper.
