Tabular view of the drawer: dismissal by pulling down

I created a box-like window that appears when the user touches a button. The drawer slides out from the bottom of the screen and fills the entire screen.

The box is actually UITableViewController, so there is a table in this box.

If I have several lines, the user can click the title (this is actually a transparent button), and the box will move down and it will be rejected. See the figure below, where purple is actually the view controller under the drawer.
