Add UITapGesture to close menu

[Jackson0111]

I've been trying to figure out how to close the menu when user taps somewhere on the screen. When users don't pick an option, or try to type something in a textField, I want to close the menu to keep the UI clean. How can I achieve this?

You may need to set up a view to detect the use click outside the menu when it expanding. And control the setExpanding to close the menu.

I got it! Thanks! This whole time I thought .expanding is a get only function for some reason...

I'm still having trouble to achieve goal. When I add a tap gesture recognizer, the dropdown menu becomes disabled. Any suggestions how I can add the tap gesture outside the menu frame?

I'm trying to do this with the code below:

` func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool {

    let point : CGPoint = touch.locationInView(self.view)

    let pointInSubview : CGPoint = self.view.convertPoint(point, fromView: self.view)

    if !CGRectContainsPoint(self.categoryMenu.frame, pointInSubview) {

        print("tapped outside category menu")

// self.view.removeGestureRecognizer(dropDownMenuTap)

// return false

    }else {

        print("tapped inside category menu")

    }

    self.view.removeGestureRecognizer(dropDownMenuTap)

    return true

}`

I have 6 options in categoryMenu, the output is all correct except when I tap on the last two columns in the menu, which is super weird, any thoughts maybe?

Alright, I finally solved it with this https://gist.github.com/sburlot/9856a15119985a6f1a87 kind of code. I couldn't figure out why the menu's frame was wrong when touch is detected, so i just manually added 85 to its height to make it longer.

If anyone else has a better way of doing this, please share!

@chinnuios This is different issue, please create another issue for your question. And it's better to provide more detail and code about how you use it.
