In viewDidLoad add UITapGestureRecognizer to the view

UITapGestureRecognizer *singleFingerTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleSingleTap:)];

[_PromoView addGestureRecognizer:singleFingerTap];

//The event handling method
- (void)handleSingleTap:(UITapGestureRecognizer *)recognizer{
  //Do animation here...

  _PromoView.hidden = YES;

}

This is blur view code, Use search before asking question https://stackoverflow.com/questions/17041669/creating-a-blurring-overlay-view – Clown Oct 03 '17 at 07:48
Also, alertview is a pop-up what do you mean? You can use UIViewAnimation and try which one is suits for you. – Clown Oct 03 '17 at 07:50

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!
