How can I change the color of UISearchBar "cancel" button in Swift 3?

Question

I am having trouble getting anything to work. I have a UISearchBar in my UIViewController. I just want to simply change the color of "Cancel" because the default blue does not really go well with my design. I would like it to also work on iOS 8. I found the following but it is not working for me:

(UIBarButtonItem.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self])).tintColor = UIColor.greenColor()

Type UIBarButtonItem has no member appearanceWhenContainedInInstancesOfClasses

I believe this is not even in swift 3 and I am having trouble trying to convert it...

Answer 1

appearance() just returns Self, in this case a UIBarButtonItem instance. Just use tintColor:

UIBarButtonItem.appearance().tintColor = .green
