UITapGestureRecognizer not working when setting target programmatically

Question

I'm trying to add tap event listener on an UIImageView inside UITableViewCell so I added an UITapGestureRecognizer on it and used this code

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        ...
        cell.editTap.addTarget(self, action: #selector(ProfileTVC.editTapped(sender:))) 
        //editTap is an UITapGestureRecognizer
        ...
    }
}

func editTapped(sender: UITapGestureRecognizer) {
    print("tapped")
    if sender.state == UIGestureRecognizerState.ended {
        let tapLocation = sender.location(in: self.tableView)
        if let tapIndexPath = self.tableView.indexPathForRow(at: tapLocation) {
            if fields[tapIndexPath.row].field == "languages_spoken" {

            } else if fields[tapIndexPath.row].field == "password" {

            } else {

            }
        }
    }
}

but when I'm tapping on my UIImageView the editTapped is not being called. Also UIImageView's user interaction is enabled

What is `editTap`? Where are you actually creating the `UITapGestureRecognizer`? — rmaddy, May 10 '18 at 14:16
I've edited my post. `editTap` is an ``UITapGestureRecognizer @rmaddy — Amir_P, May 10 '18 at 14:20
maybe there is a view overlaps editTap, use hierarchy debug to find it. @Amir_P — A.Munzer, May 10 '18 at 14:23

You add target not gesture

  let tapPress = UITapGestureRecognizer(target: self, action: #selector(ProfileTVC. editTapped(_:)))
 cell.editTap.addGestureRecognizer(tapPress)

//

@objc func editTapped(_ gestureRecognizer:UIGestureRecognizer)
{ 


}

You can't add UITapGestureRecognizer with "addTarget"

Change addTarget method with this one in your CellForRowAt function;

let tapGesture = UITapGestureRecognizer(target: self, action: #selector(ProfileTVC.editTapped(sender:)))
cell.editTap.addGestureRecognizer(tapGesture) //editTap should be the ImageView inside cell.

Did you try my solution? I think you are adding in a wrong way. – Emre Önder May 10 '18 at 14:21
yes it's working but my question is that why created gesture recognizer inside story board not working this way? – Amir_P May 10 '18 at 14:26
Do you have dynamic or static cells? – Emre Önder May 10 '18 at 14:27
dynamic cells d – Amir_P May 10 '18 at 14:27
So app can't know which cells have gesture recognizer or which it should add gesture recognizer. I'm not sure If you add one gesture recognizer to a dynamic cell and work it for all... – Emre Önder May 10 '18 at 14:29
The code in this answer isn't valid and won't compile since `cell.editTap` is a `UITapGestureRecognizer`. – rmaddy May 10 '18 at 15:16
