 let alert = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)            
 alert.modalPresentationStyle = .popover


 let image = UIImage(named: "logoCircle")
 let imageView = UIImageView()
 imageView.image = image
 imageView.frame =  CGRect(x: 25, y: 18, width: 24, height: 24)
 alert.view.addSubview(imageView) 

 let image1 = UIImage(named: "icshare")
  let imageView1 = UIImageView()
  imageView1.image = image1
  alert.view.addSubview(imageView1)
  imageView1.frame = CGRect(x: 25, y: 75, width: 24, height: 24)

 let shareExternal = UIAlertAction(title: NSLocalizedString("Share External Link", comment: ""), style: .default) { action in
        }
 let shareInApp = UIAlertAction(title: "Share within", style: .default)   {
                action in
            } 

  alert.addAction(shareInApp)
  alert.addAction(shareExternal)


    if let presenter = alert.popoverPresentationController
    {
            presenter.sourceView = button
            presenter.sourceRect = button.bounds
    }
    present(alert, animated: true, completion: nil)
