How to closed when in tap outside ?

[smart-technology]

hi how i can close menu when in tap outside menu ?

[evnaz]

At the moment there is no such possibility. To hide the side menu you can call hideSideMenuView() function in any view controller.

[elsesiy]

@smart-technology Shouldn't be too difficult to implement this feature yourself. Just register a tap recognizer in your view controllers which triggers hideSideMenuView(), or am I missing something?

[pappzsolt100]

My solution for this. I've added the following code in ENSideMenu.swift main init: let outterView = UIView(frame: CGRectMake(0, 0, sourceView.bounds.width, sourceView.bounds.height)) outterView.backgroundColor = UIColor.clearColor() let tapRecognizer = UITapGestureRecognizer(target: self, action: "hideSideMenu") outterView.addGestureRecognizer(tapRecognizer) sideMenuContainerView.addSubview(outterView)

and adjust the menu width and animation like this:

public convenience init(sourceView: UIView, menuViewController: UIViewController, menuPosition: ENSideMenuPosition) { ... let menuFrame = CGRectMake(0, 0, sideMenuContainerView.bounds.width-30, sideMenuContainerView.bounds.height) self.menuViewController.view.frame = menuFrame ... }

func updateFrame() { ... isMenuOpen ? 0 : -sourceView.frame.size.width-0.0 : ... }

private func toggleMenu (shouldOpen: Bool) { ... destFrame = CGRectMake((shouldOpen) ? -2.0 : -sourceView.frame.size.width, 0, sourceView.frame.size.width, height) ... }

I hope its help!

@pappzsolt100 your solution is not perfect and so complex.

Quick workaround, but it's not clear too:

        outterView = UIView(frame: CGRectMake(sideMenuContainerView.frame.width, 0,
            sourceView.frame.width - sideMenuContainerView.frame.width,
            sourceView.frame.height))
        outterView.backgroundColor = UIColor.clearColor()
        let tapRecognizer = UITapGestureRecognizer(target: self, action: "hideSideMenu")
        outterView.addGestureRecognizer(tapRecognizer)
        outterView.userInteractionEnabled = false
        sourceView.addSubview(outterView)

and change user interaction of outerView in

private func toggleMenu (shouldOpen: Bool) {
        outterView.userInteractionEnabled = shouldOpen

it's all ! Have a nice day!

[mortenholmgaard]

Works great!

[lakhshya]

@PankovSerge it works fine. Thanks.

[jackandjill]

@PankovSerge where does your code go in to?

[jackandjill]

@lakhshya Where did you put this code?

[lakhshya]

Define outterView in ENSideMenu private var outterView: UIView = UIView()

Add @PankovSerge 's code in the public init of ENSideMenu

[jackandjill]

@lakhshya WORKS PERFECT! thankyou.

[DagarAmit]

i can't click on item over outterView. I use .removeView method, but its work only one time. Please give me suggetion

[DagarAmit]

Thank you..its WORK!!!

[zishanj]

The solution of @PankovSerge works perfectly. Just in case if you have modified the width of ENSideMenu like sideMenu?.menuWidth = 220, then you have to put

outterView.frame = CGRectMake(sideMenuContainerView.frame.width, 0, sourceView.frame.width - sideMenuContainerView.frame.width,
            sourceView.frame.height)

again in the end of updateFrame() function

Thanks @zishanj !! 👍

Swift 3.0 with animated dimming

        //beefore sideMenuContainerView!
        outterView = UIView(frame: CGRect(x:0, y:0,width:sourceView.frame.width,height:sourceView.frame.height))
        outterView.backgroundColor = UIColor.black
        //outterView.layer.opacity=0.2
        let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(ENSideMenu.hideSideMenu))
        outterView.addGestureRecognizer(tapRecognizer)
        outterView.isUserInteractionEnabled = false
        outterView.isHidden = true
        outterView.alpha=0
        sourceView.addSubview(outterView)

and in toggleMenu

// Fade in/out
        if shouldOpen {
            outterView.isUserInteractionEnabled = shouldOpen
            outterView.isHidden = !shouldOpen
            UIView.animate(withDuration: 0.4, delay: 0.0, options: UIViewAnimationOptions.curveEaseIn, animations: {self.outterView.alpha = 0.5}, completion: nil)
        } else  {
            UIView.animate(withDuration: 0.4, delay: 0.0, options: UIViewAnimationOptions.curveEaseIn, animations: {self.outterView.alpha = 0.0}, completion: {Void in
                self.outterView.isUserInteractionEnabled = shouldOpen
                self.outterView.isHidden = !shouldOpen
            })
        }
