添加subveiw时,MKMapview不响应触摸

所以我在MKMapview的顶部添加了一个子视图。当我添加子视图时,MKMapview不允许我滚动更改地图的位置。但是,它仍然可以使用所有UI手势。

这是我的主要viewcontroller代码:

 class mapViewController: UIViewController {


    enum CardState {
        case expanded
        case collpased
    }

    var slideUpCardViews : mapSearchCardViewController!
    var visualEffectview : UIVisualEffectView!

    let cardHeight : CGFloat = 667
    let CardHandleHeight : CGFloat = 35

    var cardVisible = false
    var nextState : CardState {
        return cardVisible ? . collpased : .expanded
    }

    var runningAnimations = [UIViewPropertyAnimator]()
    var animationProgressWhenIntreupted : CGFloat = 0

    func setUpCard() {
        visualEffectview = UIVisualEffectView()
        visualEffectview.frame = self.view.frame
        self.view.addSubview(visualEffectview)

        slideUpCardViews = mapSearchCardViewController(nibName: "mapSearchCardView", bundle: nil)
        self.addChildViewController(slideUpCardViews)
        self.view.addSubview(slideUpCardViews.view)

        slideUpCardViews.view.frame = CGRect(x: 0, y: self.view.frame.height - 100
            , width: self.view.bounds.width, height: cardHeight)

        slideUpCardViews.view.clipsToBounds = true

        let tapGestureRecog = UITapGestureRecognizer(target: self, action: #selector(self.handleCardTap(recognizer:)))
        let panGestureRecog = UIPanGestureRecognizer(target: self, action: #selector(self.handleCardPan(recognizer:)))

        slideUpCardViews.SearchCardHandleBar.addGestureRecognizer(tapGestureRecog)
        slideUpCardViews.SearchCardHandleBar.addGestureRecognizer(panGestureRecog)
    }

    @objc func handleCardTap(recognizer:UITapGestureRecognizer) {


    }

    @objc func handleCardPan(recognizer:UIPanGestureRecognizer) {
        switch recognizer.state {
        case .began:
            startInteractiveTransition(state: nextState, duration: 0.9)
        case .changed:
            let translationFunction = recognizer.translation(in: self.slideUpCardViews.SearchCardHandleBar)
            var fractionComplete = translationFunction.y / cardHeight
            fractionComplete = cardVisible ? fractionComplete : -fractionComplete
            updateInteractiveTransition(franctionCompleted: fractionComplete)

        case .ended:
            continueInteractiveTransition()
        default:
            break
        }
    }

    func animationTransitionIfNeeded (state:CardState, duration: TimeInterval) {
        if runningAnimations.isEmpty {
            let frameAnimator = UIViewPropertyAnimator(duration: duration, dampingRatio: 1) {
                switch state {
                case .expanded:
                    self.slideUpCardViews.view.frame.origin.y = self.view.frame.height - self.cardHeight + 100
                case .collpased:
                    self.slideUpCardViews.view.frame.origin.y = self.view.frame.height - self.CardHandleHeight
                }
            }
            frameAnimator.addCompletion {_ in
                self.cardVisible = !self.cardVisible
                self.runningAnimations.removeAll()
            }

            frameAnimator.startAnimation()
            runningAnimations.append(frameAnimator)

            let searchOpacityAnimator = UIViewPropertyAnimator(duration: duration, curve: .linear) {
                switch state {
                case . expanded:
                    self.slideUpCardViews.SearchCardHandleBar.layer.opacity = 0.05
                case .collpased:
                    self.slideUpCardViews.SearchCardHandleBar.layer.opacity = 0.65
                }
            }
            searchOpacityAnimator.startAnimation()
            runningAnimations.append(searchOpacityAnimator)

            let blurAnimator = UIViewPropertyAnimator(duration: duration, curve: .linear) {
                switch state {
                case .expanded:
                    self.visualEffectview.effect = UIBlurEffect(style: .light)
                case .collpased:
                    self.visualEffectview.effect = nil
                }
            }
            blurAnimator.startAnimation()
            runningAnimations.append(blurAnimator)

        }
    }
    func startInteractiveTransition(state: CardState, duration: TimeInterval) {
        if runningAnimations.isEmpty {
            animationTransitionIfNeeded(state: state, duration: duration)

        }
        for animator in runningAnimations {
            animator.pauseAnimation()
            animationProgressWhenIntreupted = animator.fractionComplete

        }
    }

    func updateInteractiveTransition(franctionCompleted:CGFloat) {
        for animator in runningAnimations {
            animator.fractionComplete = franctionCompleted + animationProgressWhenIntreupted
        }
    }

    func continueInteractiveTransition() {
        for animator in runningAnimations {
            animator.continueAnimation(withTimingParameters: nil, durationFactor: 0)

        }
    }

这是我添加的子视图的代码:

        for events in superEventArray {
            if events.eventTypeSubmit == MapCardSearchBar.text {
            eventSearchResults.append(events)
            }
        }
    mapCardTableView.reloadData()
    }

    func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
         eventSearchResults.removeAll()
        mapCardTableView.reloadData()
        }

    func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
    print(superEventArray)
    print("search bar clicked")
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        print("returned superevent array count")
        return superEventArray.count
    }

    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        if eventSearchResults.count == 0 {
            print("event search count = 0")
        let cellIdentifier = "eventTableViewCell"
        let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! eventFeedTableViewCell

        cell.eventTitleLabel.text = superEventArray[indexPath.row].eventTitleSubmit
        cell.eventTypeLabel.text = superEventArray[indexPath.row].eventTypeSubmit
        cell.eventLocationLabel.text = superEventArray[indexPath.row].eventLocationSubmit
        cell.evenImageView.image = UIImage(named: "car")
        return cell
        }
        else {
            print("loading event search table")
            let cellIdentifier = "eventTableViewCell"
            let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as! eventFeedTableViewCell

            cell.eventTitleLabel.text = eventSearchResults[indexPath.row].eventTitleSubmit
            cell.eventTypeLabel.text = eventSearchResults[indexPath.row].eventTypeSubmit
            cell.eventLocationLabel.text = eventSearchResults[indexPath.row].eventLocationSubmit
            cell.evenImageView.image = UIImage(named: "car")
            return cell
        }
    }


    @IBOutlet weak var SearchCardHandleBar:RoundedSearchView!

    @IBOutlet weak var MapCardSearchBar: UISearchBar!

    @IBOutlet weak var mapCardTableView: UITableView!
}

我只是在使用地图视图时遇到麻烦,并且不想在添加子视图后滚动。

提前谢谢。
