How to customise the UISearchBar cancel button

I have a @IBOutlet weak var searchBar: UISearchBar! and I'm trying to change the font and color of the cancel button with but it's not working. The code I'm using is the following:

fileprivate static func applyStyle() {
            let appearance = UIBarButtonItem.appearance()
            let commonAttributes: [NSAttributedString.Key: Any] = [
                .font: UIFont.bodySmall,
                .foregroundColor: ColorEnum.black,
                .kern: NSNumber(value: Float(NLLetterSpacing.bodySmall))
            ]
            appearance.setTitleTextAttributes(commonAttributes, for: .normal)
            appearance.setTitleTextAttributes(commonAttributes, for: .highlighted)
            appearance.setTitleTextAttributes([
                .font: UIFont.bodySmall,
                .foregroundColor: ColorEnum.pinkishGrey,
                .kern: NSNumber(value: Float(NLLetterSpacing.bodySmall))
            ], for: .disabled)
        }

However, I also have a weak var searchController: UISearchController? and the code it's working for it's searchController.searchBar.

Solution

  • Adding

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

    should do the trick, then you could easily get rid of the appearance
