I've disabled the share button on the navigation bar but it still shows up?

Probably a newbie question but I'm having a hard time getting rid of the rightBarButtonItem entirely. Any help would be much appreciated!

I figured it out. You have to subclass QLPreviewController and then disable it in the viewDidLoad, viewDidAppear, and viewWillAppear. Then you must replace the superclass instances of the QLPreviewController with the subclass.

this work for me

class QLSPreviewController : QLPreviewController {
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
    }
    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(true )
        //This hides the share item
        if let add =  self.childViewControllers.first as? UINavigationController {
            if let layoutContainerView  = add.view.subviews[1] as? UINavigationBar {
                 layoutContainerView.subviews[2].subviews[1].isHidden = true
            }
        }
    }
}

I am using layoutContainerView.subviews[1].subviews[1].isHidden = true then its works for me.
