I\'d like to change the text from "Cancel" to "Done" of the Cancel button inside the UISearchBar in iOS 8. I am using UISearchControll

Answer 1

 for view in (UISearchBar.subviews[0]).subviews{
             if let button = view as? UIButton{
             button.setTitleColor(UIColor.whiteColor(), forState: .Normal)
             button.setTitle("Cancel", forState:.Normal)
            }
     }

self.subviews[0]).subviews contain UISearchBarBackground,UISearchBarTextField,UINavigationButto‌​n in which UINavigationButton is subclass of UIButton.Check for View as UIButton and if yes then change property of UIButton.
