searchBarTextDidBeginEditing not being called when i use it in navigation controller Swift 3.

Question

I have searched for hours trying to solve my problem, but i could not find any solutions.

My problem is that i have a SearchBar inside my navigation bar. I did setup my SearchBar like this:

lazy var searchBar = UISearchBar(frame: CGRect.zero)



    override func viewDidLoad() {

        super.viewDidLoad()



        searchBar.delegate = self

        searchBar.placeholder = "Search"



        navigationItem.titleView = searchBar



    }

When i try to call for example a function from the protocol UISearchBarDelegate it won't respond.
The function is for example:

func searchBarTextDidBeginEditing(searchBar: UISearchBar) {



        print("Did run")

    }

This function does not execute. How would i make functions from UISearchBarDelegate execute programmatically inside a navigation bar? The reason for that i do this programmatically is because i use the search bar inside a navigation bar

Answer 1

Your delegate function is just a bit different from the right one, at the parameter. It should be:

func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
  //code
}
