Programattically set barbutton " System Item"

Question

I want to set share button on rightbarbuttonitem of navigation controller. I don't want to add custom images , I want use share button image provided by Xcode.This is how I do in storyboard. I set Style , and set System_Item as Action.

Now the question is how do I set System_Item programatically, if I create barbuttonitem programatically ?

let shareButton = UIBarButtonItem(title: "",
                                  style: .plain,
                                  target: self,
                                  action: #selector(shareAction(sender:)))
    shareButton.tintColor = AppColor.barButtonColor

    navigationItem.rightBarButtonItem = shareButton

Answer 1

you need to use UIBarButtonSystemItemAction option to get share action directly

   let share = UIBarButtonItem(barButtonSystemItem: .action, target: self, action: #selector(shareAction(sender:)))
    shareButton.tintColor = AppColor.barButtonColor
    navigationItem.rightBarButtonItem = share

and handle the action as like

@objc func shareAction(sender: UIBarButtonItem) {

}
