Question

I am trying to get the frame of an image shown in a UITaBarItem. I can get the view of any UITabBarItem but can't able to get the frame of only image part of any UITabBarItem. Adding an screenshot of my views

Answer 1

For getting UIBarButtonItem's view

public extension UIBarButtonItem {

    var view: UIView? {
        guard let view = self.value(forKey: "view") as? UIView else {
            return nil
        }
        return view
    }
}

For getting UIImageView from UIBarButtonItem view:

let barItemImageView = self.navigationItem.rightBarButtonItem?.view.subviews.filter { view in
        view is UIImageView
        }.first

This will return the UIImageView of my right UIBarButtonItem
