Get the sender object from UITapGestureRecognizer

 Solution:

                let tapGestureRecognizer = UITapGestureRecognizer(target: vc, action: #selector(vc.tapEventAction(sender:)))

                cell.img.addGestureRecognizer(tapGestureRecognizer)

                }

When tap called 

    @objc func tapEventAction(sender: UITapGestureRecognizer) {

        let btn = sender.view as! UIImageView

}
