You can you isSelected variable. And add different image for button state.

imgCheck.setImage(UIImage(named: "uncheck.png"), for: .selected)
imgCheck.setImage(UIImage(named: "check.png"), for: .normal)

Add UITapGestureRecognizer on your button like this. or you can use UIButton own property isSelected ?

@IBOutlet weak var myBtn: UIButton!

In your Viewdidload method add these line

let tapGesture = UITapGestureRecognizer(target: self, action: "handleTap")  

myBtn.addGestureRecognizer(tapGesture)

func handleTap(sender: UITapGestureRecognizer) {

  if sender.state == .ended {
      // handling code
  }
  else if sender.state == .began {

  }
}

Add gesture according to your needs.I used long tap and tap gesture

This code worked for me. Globally define var isclick = false

 func CarDeliverCost() {
        if (!isclick){

            imgUnCheck.image = UIImage(named: "check.png")
            isclick=true



        }
        else
        {
            imgUnCheck.image = UIImage(named: "uncheck.png")
            isclick=false



        }
    }
