UIBarButtonItem: How can I find its frame?

Question

I have a button in a toolbar. How can I grab its frame? Do UIBarButtonItems not have a frame property?

Answer 1

in Swift 4.2 and inspired with luca

extension UIBarButtonItem {

    var frame:CGRect?{
        return (value(forKey: "view") as? UIView)?.frame
    }

}


guard let frame = self.navigationItem.rightBarButtonItems?.first?.frame else{ return }
