ios - removeFromSuperview() 几个 subview

Question

我在 ViewHelper 类中有一些函数:

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)
    }

然后我调用并关闭了我的弹出窗口(它完美地工作):

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)
        }

但是我想在我的 showFrontPopOver 方法中添加一个 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)
}

事实证明这个方法行不通:

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

因为他不再申请这个图层和 View 。我将 2 个 subview 强加于另一个可能是不正确的。但是我不知道如何在我的表格下实现模糊效果

我该如何修复它？关闭所有内容，包括我的表单和 blurView， map 除外。

你需要给每个 subview 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)
 }
