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

You can get the size of tabBarItem image using `self.tabBarItem.selectedImage?.size` — Nilesh R Patel, Feb 27 '19 at 07:01

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

One of the simple solution is

guard let view = self.tabBarVC?.tabBar.items?[0].valueForKey("view") as? UIView 
else 
 {
    return
 }
let frame = view.frame

OR

extension UITabBar {

func getFrameForTabAt(index: Int) -> CGRect? {
    var frames = self.subviews.compactMap { return $0 is UIControl ? $0.frame : nil }
    frames.sort { $0.origin.x < $1.origin.x }
    return frames[safe: index]
  }

}

extension Collection {

subscript (safe index: Index) -> Element? {
    return indices.contains(index) ? self[index] : nil
}

}

I know about your first solution. I am using it. I need the uiimage part only — Md. Sulayman, Feb 27 '19 at 06:54
