Swift : show searchbar when scroll up and hide it when scroll down

I am new to Ios develpomment, I added a Searchbar into the navigation item What I would like to implement is when I scroll Up the tableview I want to hide the Searchbar and when show it when I scroll down

Like safari effect on iPAD /Iphone where the address bar is hiding when scrolling Down and showing when scrolling Up

  let searchController = UISearchController(searchResultsController: nil)
  searchController.searchResultsUpdater = self
  searchController.obscuresBackgroundDuringPresentation = false
  navigationItem.searchController = searchController
  definesPresentationContext = true

thank your for helping.

Solution

  • All you need to do is to hide and display your search bar when you start scrolling so for that you need to override the didBeginScrolling (check the exact name ) and add this code accordingly

    navigationItem.hidesSearchBarWhenScrolling = false
