Dismissing keyboard from UISearchBar when the X button is tapped

Question

I\'m using the UISearchBar (but not the SearchDisplayController that\'s typically used in conjunction) and I\'d like to dismiss the keyboard when you hit the \'X\' button.

Answer 1

Updated for SWIFT 3:

Suppose that the user has entered a string in searchfield and clicks x the following code works to hide keyboard when x is pressed

`

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
{
            if searchBar.text == nil || searchBar.text == ""
            {
                searchBar.perform(#selector(self.resignFirstResponder), with: nil, afterDelay: 0.1)
            }
 }
