Navigation bar with multiple buttons

Question

I have a navigation bar with a left and right button, and I need to put another button next to the right button. Does anyone know how I can go about this? Here is some code

Answer 1

  let RightBarButton = UIButton()
        RightBarButton.setTitleColor(UIColor.blueColor(), forState: .Normal)
        RightBarButton.frame = CGRectMake(30,0,30,30)
        RightBarButton.setImage(UIImage(named: "search-icon.png"), forState: .Normal)
        RightBarButton.addTarget(self, action: #selector(BaseViewController.OpenQuickLink), forControlEvents: .TouchUpInside)

        let RightBarButton2 = UIButton()
        RightBarButton2.setTitleColor(UIColor.blueColor(), forState: .Normal)
        RightBarButton2.frame = CGRectMake(0,0,30,30)
        RightBarButton2.setImage(UIImage(named: "share-icon.png"), forState: .Normal)
        RightBarButton2.addTarget(self, action: #selector(BaseViewController.Opensharelink), forControlEvents: .TouchUpInside)
        let barButtonItem1 = UIBarButtonItem(customView: RightBarButton2)

        let barButtonItem = UIBarButtonItem(customView: RightBarButton)


navigationItem.rightBarButtonItems = [barButtonItem1, barButtonItem2]
