Passing an object to custom view in Google maps SDK

Question

I have custom view (a nib with its class) that I show when user taps on map marker. I also have an array of objects from where I'd like to show data of selected object when user taps on one of the markers. I create markers from the same array in a separate method. How to I get my element in array (to show additional data) when user taps the marker ? Or is there another way to get the object from array based on pressed marker. Apart from regexing based on lon and lat etc ?

Answer 1

I solved this by adding my model to

marker.userData

example:

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

    }

}

Then later I access it in:

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
}
