Dismissing side menu by tapping anywhere

Question

I created a side menu using a container view. It slides in the main view each time i press a menu. You can find my project here: https://github.com/marybnq/side-menu

I need to dismiss it by tapping anywhere in the mainVC. How do I do it?

You can use TapGestures and check when tapped mainVc change constant of side bar — Omer Tekbiyik, Feb 06 '19 at 21:52
@OmerTekbiyik yes but I should pass data between vc and I'm not sure about how to pass the sideMenuConstraint to the other vc — Federica Benacquista, Feb 07 '19 at 13:47

Try this:

class FirstViewController: UIViewController {

@IBOutlet weak var menuConstraint: NSLayoutConstraint!

var sideMenuOpen = false
var gesture : UITapGestureRecognizer?


override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(self,
                                           selector: #selector(toggleSideMenu), name: NSNotification.Name("ToggleSideMenu"), object: nil)


    gesture = UITapGestureRecognizer(target: self, action: #selector(FirstViewController.toggleSideMenu))

}
@objc func toggleSideMenu() {
    if sideMenuOpen {
        sideMenuOpen = false
        menuConstraint.constant = -240
        self.view.removeGestureRecognizer(gesture!)
    } else {
        sideMenuOpen = true
        menuConstraint.constant = 0
        self.view.addGestureRecognizer(gesture!)
    }

}

}

Perfect! What if I want it to work in other view controllers? I used the Notification Center to pass the toggleSideMenu func but it doesn’t add the gesture — Federica Benacquista, Feb 07 '19 at 18:24
I tried to create the project from the beginning and now it works fine, thanks! — Federica Benacquista, Feb 07 '19 at 19:29

Simple:
1. Add tap gesture to view of mainVC and disable it by default
2. Enable tap gesture on showing side menu, to handle taps
3. Disable tap gesture on hiding side menu
