从 tableView 中的 selectedRow 打开 Map AnnotationView

Question

如何在 select table 查看单元格后将 MKAnnotationView 放置在指定的注释上？我是否需要在 table 视图的 didSelectRowAtIndexPath 中调用函数 mapView(_:didSelect:) ？这是我的 didselectrow 函数。我确实在 select 行中尝试使用 map.selectAnnotation，但是 returns 没有。

 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {


        let pin = filteredDetails[indexPath.row].coordinate

        let latDelta: CLLocationDegrees = 0.009
        let lonDelta: CLLocationDegrees = 0.009

        let span = MKCoordinateSpanMake(latDelta, lonDelta)
        let location = CLLocationCoordinate2DMake(pin.latitude, pin.longitude)
        let region = MKCoordinateRegionMake(location, span)

        mapView.setRegion(region, animated: true)

       // mapView.selectAnnotation(customXibView as! MKAnnotation, animated: true)

        tableView.isHidden = true


        }

这是我的地图select func.

 func mapView(_ mapView: MKMapView, didSelect view: MKAnnotationView) {

        let meridianAnnotation = view.annotation as! Details

        let customXibView = Bundle.main.loadNibNamed("CustomCalloutVIew", owner: self, options: nil)?[0] as! CustomAnnotationClass!

        customXibView?.address.text = meridianAnnotation.address
        customXibView?.phone.text = meridianAnnotation.phone

        let calloutFrame = view.frame
        customXibView?.frame = CGRect(x: (calloutFrame.size.width)-178.0, y: (calloutFrame.size.height)-220, width: 315, height: 166)


        customXibView?.blurOverlay.effect = UIBlurEffect(style: .light)
        customXibView?.layer.masksToBounds = true


        let shadowView = UIView(frame: CGRect(x: (calloutFrame.size.width)-178.0, y: (calloutFrame.size.height)-220, width: 315, height: 154))
        shadowView.translatesAutoresizingMaskIntoConstraints = false
        shadowView.backgroundColor = UIColor.clear
        shadowView.layer.borderWidth = 7.0
        shadowView.layer.borderColor = UIColor.lightGray.cgColor
        shadowView.alpha = 1.0
        shadowView.layer.cornerRadius = 10.0
        shadowView.layer.shadowOffset = CGSize(width: 4.0, height: 4.0)
        shadowView.layer.shadowOpacity = 1.0
        shadowView.layer.shadowRadius = 13.0

        view.insertSubview(shadowView, at: 0)

        view.addSubview(customXibView!)

        mapView.setCenter((view.annotation?.coordinate)!, animated: true)


    }

Answer 1

在你的didSelectRowAtIndexPath中，您传递的是 customXibView 而不是

您必须搜索与该表视图关联的注释

找到它后，您可以告诉它 select 它，方法是：

mapView.selectAnnotation

您可以使用答案从 MapView

中搜索注释

Answer 2

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {


        let pin = filteredDetails[indexPath.row].coordinate

        let latDelta: CLLocationDegrees = 0.009
        let lonDelta: CLLocationDegrees = 0.009

        let span = MKCoordinateSpanMake(latDelta, lonDelta)
        let location = CLLocationCoordinate2DMake(pin.latitude, pin.longitude)
        let region = MKCoordinateRegionMake(location, span)

        mapView.setRegion(region, animated: true)

      mapView.selectAnnotation(filteredDetails[indexPath.row], animated: true)

        tableView.isHidden = true


        }
