ios - 将对象传递给 Google map SDK 中的自定义 View

Question

我有自定义 View (一个 Nib 及其类)，当用户点击 map 标记时会显示该 View 。我还有一组对象，当用户点击其中一个标记时，我想从中显示所选对象的数据。我用单独的方法从同一个数组创建标记。当用户点击标记时，如何让我的元素进入数组(以显示附加数据)？或者是否有另一种方法可以根据按下的标记从数组中获取对象。除了基于 lon 和 lat 等的正则表达式之外？

Answer 1

我通过添加我的模型来解决这个问题

marker.userData

例子:

func addMarkers(){

    for place in places{

        let marker = GMSMarker()
        let placeLat = place.latitude
        let placeLon = place.longitude
        marker.position = CLLocationCoordinate2D(latitude: CLLocationDegrees(placeLat), longitude: CLLocationDegrees(placeLon))
        marker.appearAnimation = .pop
        marker.map = mpView
        marker.userData = place

    }

}

然后我在以下位置访问它:

func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {

    let title = (marker.userData as! placeModel).name
    let add = (marker.userData as! placeModel).address
    let id = (marker.userData as! placeModel).id
    let image = (marker.userData as! placeModel).image
    let imageAddressInDocuments = ("\(getDocumentsDirectory())\(image)")
    print("image address in documents %@", imageAddressInDocuments )
    var infoWindow = Bundle.main.loadNibNamed("custView", owner: self, options: nil)?.first as! custView
    infoWindow.titleLabel.text = title
    infoWindow.addressLabel.text = add
    infoWindow.restaurantImage.image = image != "" ? UIImage(contentsOfFile: imageAddressInDocuments) : UIImage(named: "addImage")


    return infoWindow
}
