extension UISearchBar {
var cancelButton : UIButton? {
    let topView: UIView = self.subviews[0] as UIView

    if let pvtClass = NSClassFromString("UINavigationButton") {
        for v in topView.subviews {
            if v.isKind(of: pvtClass) {
                return v as? UIButton
            }
        }
    }

    return nil
}
