Swift 4 hide view and fill the blank

I want to make the search bar disappear by clicking the navigation bar item and make the collection view to fill the blank, animated obviously. ( like making the screen move upwards because the keyboard is showing )
is it Possible also to make it disappear when I scroll down an appear when I scroll up again ?
I dont think both ways will work at the same time but anyway I want to know how to make each way work.
thanks for the help :)
A collection view is a scroll view. A scroll view can have a delegate. A scroll view's delegate is told when the scroll view is scrolling. Therefore you can do anything you like in response to the user scrolling the scroll view, including moving the search bar.

ScrollView error in Xcode 4.5

To make my scroll view scroll, i need to check the box "bounce vertically". But when i make it, while scrolling the page. The page automatically scrolls itself back to first state if i dont keep my finger holded on the screen. Please help me.
uncheck the box bounce vertically and check the box bounces. on the scroll view section of the IB right on the top check the first three boxes. show vertical... show horizontal.... scrolling enabled.
that should do the trick. let me know if this works.
