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

I used a view on the bar button item with a tag on the view:

for view in bottomToolbar.subviews {
   if let stackView = view.subviews.filter({$0 is UIStackView}).first {
       //target view has tag = 88
       if let targetView = stackView.subviews.filter({$0.viewWithTag(88) != nil}).first {                                
          //do something with target view
   }
}

}
