Question

我在ViewHelper类中有一些功能：

class func showFrontPopOver(popOver:UIView,view:UIView) {
        let animation = AnimationType.zoom(scale: 1.5)
        popOver.animate(animations: [animation])
        popOver.layer.cornerRadius = 10
        popOver.center = view.center
        view.addSubview(popOver)
    }
class func hidePopOver(popOver:UIView, view:UIView) {
        UIView.transition(with: view, duration: 0.25, options: [.transitionCrossDissolve], animations: {
            popOver.removeFromSuperview()
        }, completion: nil)
    }

然后我调用并关闭我的弹出窗口（它工作正常）：

func mapView(_ mapView: GMSMapView, didTap marker: GMSMarker) -> Bool {
        ViewHelper.showFrontPopOver(popOver: popOver, view: self.view)
        return true
    }



func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D) {
            ViewHelper.hidePopOver(popOver: self.popOver, view:self.view)
        }

但是我不想在我的showFrontPopOver方法中添加blurView：

class func showFrontPopOver(popOver:UIView,view:UIView) {
    let animation = AnimationType.zoom(scale: 1.5)
    popOver.animate(animations: [animation])
    popOver.layer.cornerRadius = 10
    popOver.center = view.center
    let blurEffect = UIBlurEffect(style: .light)
    let blurVisualEffectView = UIVisualEffectView(effect: blurEffect)
    blurVisualEffectView.frame = view.bounds
    blurVisualEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
    view.addSubview(blurVisualEffectView)
    view.addSubview(popOver)
}

事实证明该方法无效：

 func mapView(_ mapView: GMSMapView, didTapAt coordinate: CLLocationCoordinate2D) {
                ViewHelper.hidePopOver(popOver: self.popOver, view:self.view)
            }

因为他不再应用于该图层和视图。我强加2个子视图可能是不正确的。但是我不知道如何在我的形式下实现模糊效果

我该如何解决？关闭除地图之外的所有内容，包括窗体和blurView。

您需要为每个子视图添加一个标签

op1

class func showFrontPopOver(popOver:UIView,view:UIView) {
    let animation = AnimationType.zoom(scale: 1.5)
    popOver.animate(animations: [animation])
    popOver.layer.cornerRadius = 10
    popOver.center = view.center
    let blurEffect = UIBlurEffect(style: .light)
    let blurVisualEffectView = UIVisualEffectView(effect: blurEffect)
    blurVisualEffectView.frame = view.bounds
    blurVisualEffectView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
    popOver.tag = 11
    blurVisualEffectView.tag = 11
    view.addSubview(blurVisualEffectView)
    view.addSubview(popOver)
}

然后

class func hidePopOver(popOver:UIView, view:UIView) {
        UIView.transition(with: view, duration: 0.25, options: [.transitionCrossDissolve], animations: {
            view.subviews.forEach {
              if $0.tag == 11 {
                $0.removeFromSuperview()
              }
        }, completion: nil)
 }

op2

class func hidePopOver(view:UIView) {
        UIView.transition(with: view, duration: 0.25, options: [.transitionCrossDissolve], animations: {
            view.subviews.last?.removeFromSuperview()
            view.subviews.last?.removeFromSuperview()

        }, completion: nil)
 }

removeFromSuperview（）几个子视图
