UISearchController: show results even when search bar is empty

Question

As I understand, the default behaviour of UISearchController is:

1. On tapping search bar, background is dimmed and \'cancel\' button is shown.

Answer 1

You can simply implement the UISearchResultsUpdating protocol and set the results controller view to always show in updateSearchResultsForSearchController:

 func updateSearchResultsForSearchController(searchController: UISearchController) {

   // Always show the search result controller
   searchController.searchResultsController?.view.hidden = false

   // Update your search results data and reload data
   ..
}

This works because the method is called even when the search bar is activated, without any text.
