Ios 在UIView上显示UIView，就像在UIView上单击PopUpView按钮一样？

我有UiView（PromoView）， 我想在UIButton的操作上打开PromoView，当弹出视图打开时，也设置背景模糊，当用户单击视图中的任何位置时，弹出视图将被隐藏。 这是我的密码

-(IBAction)PromoCode_btn:(id)sender
{
    _PromoView.hidden=NO;
    _PromoView.transform = CGAffineTransformMakeScale(0.01, 0.01);
    [UIView animateWithDuration:0.3 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
    self.view.alpha=0.5;
    _PromoView.transform = CGAffineTransformIdentity;
    } completion:^(BOOL finished){
  }];
}

它只是用动画打开，

帮助我在

viewdiload

中将

UITapGestureRecognizer

添加到视图中的代码…

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;

}

在

viewdiload

中将

uitappesturerecognizer

添加到视图中

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;

}

试试这个

@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
    }
}
