How to exit from the search on clicking on Cancel button?


You need to implement the UISearchBarDelegate :

class ViewController: UIViewController, UISearchBarDelegate {    @IBOutlet weak var searchBar: UISearchBar!

Set the search bar delegate to self

 override func viewDidLoad() {        super.viewDidLoad()        searchBar.showsCancelButton = true        searchBar.delegate = self

and then implement the butCancelSearchAction delegate function to do whatever you need to do to cancel the search action and reset the search text:

func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {    // Do some search stuff}func searchBarCancelButtonClicked(searchBar: UISearchBar) {    // Stop doing the search stuff    // and clear the text in the search bar    searchBar.text = ""    // Hide the cancel button    searchBar.showsCancelButton = false    // You could also change the position, frame etc of the searchBar }


class MyController: UIViewController, UISearchBarDelegate {    // Called when search bar obtains focus.  I.e., user taps     // on the search bar to enter text.    func searchBarTextDidBeginEditing(searchBar: UISearchBar) {        searchBar.showsCancelButton = true    }    func searchBarCancelButtonClicked(searchBar: UISearchBar) {        searchBar.text = nil        searchBar.showsCancelButton = false        // Remove focus from the search bar.        searchBar.endEditing(true)        // Perform any necessary work.  E.g., repopulating a table view        // if the search bar performs filtering.     }}


Try. It works fine.

class MyViewController: UIViewController, UISearchBarDelegate {    func searchBarTextDidBeginEditing(_searchBar: UISearchBar) {        searchBar.setShowsCancelButton(true, animated: true)        //write other necessary statements    }    func searchBarCancelButtonClicked(_searchBar: UISearchBar) {        searchBar.text = nil        searchBar.setShowsCancelButton(false, animated: true)        // Remove focus from the search bar.        searchBar.endEditing(true)     }}
