How to change the colour of the 'Cancel' button on the UISearchBar in Swift

Question

I have added a UISearchBar to the top of my PFQueryTableViewController. I have changed the colour of the searchBar to be the colour of my app, but

Answer 1

Base on Nick89's code , I changed like that for Swift 3.1

let cancelButtonAttributes: [String: AnyObject] = [NSForegroundColorAttributeName: UIColor.white]

UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes(cancelButtonAttributes, for: .normal)

I want to change on UISearchBar only instead of all UIBarButton, so I'm using like UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self])
