End action slider is targeted to when slider is done editing

I want my swift code to to end the connection the slider has with object pg after the action with the slider is completed. So right now when you click of the imageview pg then use the slider the slider is connected to the size of the imageview. I want the size of the iamgeview to be controlled like. Press on pg - then press on slider and drag slider to size you want - when slider is not touch you can not change the size of pg without first touching it. I have a gif below to show you what is happening.

import UIKit
class ViewController: UIViewController {
    var image1Width2: NSLayoutConstraint!
    var image1Height2: NSLayoutConstraint!
    var currentView: UIView?
    var greenTransition: CGAffineTransform?
    var slider = UISlider()
    var PG = UIImageView()
    var btn = UIButton()
    var jake  = false
    var btnCouter = 0
    var g2 = UIPanGestureRecognizer()
    override func viewDidLoad() {
        slider.value = 0.5
        PG.isUserInteractionEnabled = true
        PG.image = UIImage(named: "c")
        g2 = UIPanGestureRecognizer(target: self, action: #selector(ViewController.g1Method))
        [PG,slider,btn].forEach {
                $0.translatesAutoresizingMaskIntoConstraints = false
        let percent1 = self.view.frame.height * 0.1

        image1Width2 =  PG.widthAnchor.constraint(equalTo:  view.widthAnchor ,multiplier:  0.06)
        image1Height2 =  PG.heightAnchor.constraint(equalTo:  view.heightAnchor ,multiplier:  0.06)


            slider.bottomAnchor.constraint(equalTo: view.bottomAnchor),
            slider.heightAnchor.constraint(equalTo: view.heightAnchor, multiplier: 0.06, constant: 0),
            slider.widthAnchor.constraint(equalTo: view.widthAnchor, multiplier: 1, constant: 0),
            slider.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant : 0),
            PG.topAnchor.constraint(equalTo: view.topAnchor, constant : percent1),
            PG.leadingAnchor.constraint(equalTo: view.leadingAnchor),


        slider.addTarget(self, action: #selector(hhh), for: .allEvents)


    @objc func hhh() {

        if jake == true {
                image1Width2.constant = CGFloat(slider.value) * view.frame.size.width * 0.10
                image1Height2.constant = CGFloat(slider.value) * view.frame.size.height * 0.10
            image1Width2.constant = CGFloat(0.5) * view.frame.size.width * 0.10
            image1Height2.constant = CGFloat(0.5) * view.frame.size.height * 0.10


    @objc func handleTapGestured(_ gesture: UIPanGestureRecognizer) {
        currentView = gesture.view
    @objc func g1Method(_ sender: UIPanGestureRecognizer){
        jake = true
        btnCouter = 1
        if jake == true {
            guard let child = sender.view else{return}
            let transitionPoint = sender.translation(in: self.view)
            let newTransition = CGAffineTransform(translationX: transitionPoint.x, y: transitionPoint.y)
            switch sender.state {
            case .ended,.cancelled:// on End
                if let existing = greenTransition {
                    greenTransition = newTransition.concatenating(existing)
                } else {
                    greenTransition = newTransition
            default://on change and other states
                if let existing = greenTransition {
                    child.transform = newTransition
                } else {
                    child.transform = newTransition



Hi @timswift,
Why not have the slider hidden at the start? You can then show the slider when the image is touched and hide it again when the focus is lost.


the slider is used to draw cgpoints so it needs to be visible at all times.

If the slider is used to draw then you should not use it for scaling as in the video
