It was the Title of NavigationItem instead of the header of TableView

iOS standard memo app, messaging app, etc. I was addicted to the movement that is displayed in the Title of NavigationItem when the TableView's HeaderView-like scrolls, because I thought that I would touch the TableView's HeaderView.

Implementation procedure

--Check ** Prefers Large Titles ** in Navigation Bar --Enter a title in Title of Navigation Item --Large Title of Navigation Item is changed to ** Automatic **.

that's all! !! It was a moment.
