Try this,
@IBAction func PromoCode_btn(_ sender: Any) {
view_background.backgroundColor = UIColor.black
view_background.alpha = 0.8
view_background.translatesAutoresizingMaskIntoConstraints = false
layoutDic["view_background"] = view_background
self.view.addSubview(view_background)
view_background.isHidden = false
self.view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|-0-[view_background]-0-|", options: NSLayoutFormatOptions(rawValue: 0), metrics: metricdict, views: layoutDic))
self.view.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "H:|-0-[view_background]-0-|", options: NSLayoutFormatOptions(rawValue: 0), metrics: metricdict, views: layoutDic))
let promoHideTap = UITapGestureRecognizer.init(target: self, action: #selector(self.promoCancelAction))
promoHideTap.delegate = self
view_background.addGestureRecognizer(promoHideTap)
_PromoView.translatesAutoresizingMaskIntoConstraints = false
layoutDic["_PromoView"] = _PromoView
view_background.addSubview(_PromoView)
_PromoView.backgroundColor = UIColor.white
_PromoView.layer.borderColor = UIColor.lightGray.cgColor
_PromoView.layer.borderWidth = 0.2
_PromoView.layer.shadowColor = UIColor.gray.cgColor
_PromoView.layer.shadowOpacity = 0.2
view_background.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "V:|-200-[_PromoView(300)]", options: NSLayoutFormatOptions(rawValue: UInt(0)), metrics: metricdict, views: layoutDic))
view_background.addConstraints(NSLayoutConstraint.constraints(withVisualFormat: "H:|-250-[_PromoView]-250-|", options: NSLayoutFormatOptions(rawValue: UInt(0)), metrics: metricdict, views: layoutDic))
}
func promoCancelAction()->Void
{
view_background.isHidden = true
}
func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldReceive touch: UITouch) -> Bool
{
// Method to recognize whether the tap originated from bg view or table view
if touch.view!.isDescendant(of: _PromoView)
{
return false
}
else
{
return true
}
}
Hope this work!
