Get titleLabel during drag and drop - ios

Question

An array of UIButton are generated programmatically. Is it possible to get the titleLabel of the UIButton triggering the drag? Or are there any ways to get info of the UIButton in the drag function?
override func viewDidLoad() {
super.viewDidLoad()
for q in question{
addButton(title:q)
}
}
func addButton(title:String){
var tbutton: UIButton = {
let button = UIButton(frame: CGRect(x: 0, y: 0,
width: buttonWidth,
height: buttonHeight))
button.center = self.view.center
button.layer.cornerRadius = 5
button.layer.masksToBounds = true
button.backgroundColor = UIColor.yellow
button.setTitleColor(.black, for: .normal)
button.setTitle(title, for: .normal)
return button
}()
view.addSubview(tbutton)
tbutton.addTarget(self,
action: #selector(drag(control:event:)),
for: UIControl.Event.touchDragInside)
tbutton.addTarget(self,
action: #selector(drag(control:event:)),
for: [UIControl.Event.touchDragExit,
UIControl.Event.touchDragOutside])
self.buttonArray.append(tbutton)
}
#objc func drag(control: UIControl, event: UIEvent) {
//print(event)
if let center = event.allTouches?.first?.location(in: self.view) {
control.center = center
}

Answer 1

class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton.init(frame: CGRect.init(x: 0, y: 0, width: 100, height: 100))
button.backgroundColor = .yellow
button.center = CGPoint.init(x: view.bounds.width / 2, y: view.bounds.height / 2)
view.addSubview(button)
let pangesture = UIPanGestureRecognizer.init(target: self, action: #selector(ViewController.panning(_:)))
button.addGestureRecognizer(pangesture)
}
#objc func panning(_ panGesture : UIPanGestureRecognizer){
let button = panGesture.view as! UIButton
switch panGesture.state{
case .changed:
button.center = panGesture.location(in: view)
panGesture.setTranslation(.zero, in: view)
default:
break
}
// here you can get the button's properties too.
}
}
