(Swift) Handling user's tap on webView

Question

I have webView and a hidden stackView(3 buttons) in the bottom of webView on my screen.

@IBOutlet weak var webView: WKWebView!
@IBOutlet weak var stackView: UIStackView!

By default, stackView is hidden, and it should be visible when user taps somewhere on the webView.

override func viewDidLoad() {
        super.viewDidLoad()
        stackView.isHidden = true
    }

How can I handle user's tap to make my 'stackView' visible?

Answer 1

You can use UITapGestureRecognizer, try this

override func viewDidLoad() {
    super.viewDidLoad()
    let tapGesture = UITapGestureRecognizer(target: self, action: #selector(handleTap))
    tapGesture.delegate = self
    webView.addGestureRecognizer(tapGesture)
   } 

  @obj func handleTap() {
      stackView.isHidden = false
    }

don't forget to add UIGestureRecognizerDelegate

if it doesn't work, you have to add following method because WKWebView already has its own gesture recognizers

func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldRecognizeSimultaneouslyWith otherGestureRecognizer: UIGestureRecognizer) -> Bool {
  return true
}
