IOS - How to hide a view by touching anywhere outside of it

Question

I\'m new to IOS programming, I\'m displaying a view when a button is clicked, using the following code inside the button method.

 @IBAction func moreButton(_         


        

Answer 1

Inside the moreButton selected, you can do something like this

 @IBAction func moreButton(_ sender: Any)
    {
        self.helpView.isHidden = false
        let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(UIViewController.dismissView))
        view.addGestureRecognizer(tap)
    }

    func dismissView() {
        self.helpView.isHidden = true
        self.view.removeGestureRecognizer(tap)
    }
