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

All the above answers didn't work for me. (Got 'Type 'NSAttributedString.Key' (aka 'NSString') has no member 'foregroundColor'' error)

Maybe because I'm at Swift 3...

Here's the slightly-modified code that worked for me:-

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

Note:-

If you are using UISearchController, insert this code to 'willPresentSearchController:' or 'didPresentSearchController:'
