Create an advanced marker

Select platform: Android iOS JavaScript

Use the GMSAdvancedMarker subclass to create basic or specific marker features, as shown below. As a subclass of GMSMarker, GMSAdvancedMarker provides markers with more expression.

Swift

let camera = GMSCameraPosition( target: coordinate, zoom: 14)
let mapID = GMSMapID(identifier: "YOUR_MAP_ID")
let mapView = GMSMapView(frame: view.bounds, mapID: mapID, camera: camera)

let marker = GMSAdvancedMarker(position: coordinate)
marker.map = mapView

Objective-C

GMSCameraPosition *camera = [GMSCameraPosition cameraWithTarget:kCoordinate zoom:16];
GMSMapID *mapID = [GMSMapID mapIDWithIdentifier:"YOUR_MAP_ID"];

self.mapView = [GMSMapView mapWithFrame:self.view.bounds mapID:mapID camera:camera];

GMSAdvancedMarker *marker = [GMSAdvancedMarker markerWithPosition:kCoordinate];
Marker.map = self.mapView;

Remove an advanced marker

Similar to GMSMarker, you can remove an advanced marker from the map by setting the map property of the GMSAdvancedMarker to nil. Alternatively, you can remove all of the overlays (including advanced markers) on the map by calling the GMSMapView clear method.

Swift

let camera = GMSCameraPosition.camera(
  withLatitude: -33.8683,
  longitude: 151.2086,
  zoom: 6
)
let mapView = GMSMapView.map(withFrame: .zero, camera: camera)
// ...
mapView.clear()

Objective-C

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.8683
                                                        longitude:151.2086
                                                             zoom:6];
mapView = [GMSMapView mapWithFrame:CGRectZero camera:camera];
// ...
[mapView clear];

If you want to make modifications to a marker after you've added it to the map, ensure that you keep hold of the GMSAdvancedMarker object. You can modify the marker later by making changes to this object.

Swift

let position = CLLocationCoordinate2D(latitude: 10, longitude: 10)
let marker = GMSAdvancedMarker(position: position)
marker.map = mapView
// ...
marker.map = nil

Objective-C

CLLocationCoordinate2D position = CLLocationCoordinate2DMake(10, 10);
GMSAdvancedMarker *marker = [GMSAdvancedMarker markerWithPosition:position];
marker.map = mapView;
// ...
marker.map = nil;

Map capabilities

The mapCapabilities property on GMSMapView adds programmatic checking for map-specific features. This is useful when wanting to know if certain map capabilities are available before calling specific APIs. The didChangeMapCapabilities function of GMSMapViewDelegate is also invoked as capabilities change. This query determines if the map view supports advanced markers.

Swift

// ...

let advancedMarker: GMSAdvancedMarker = {
GMSAdvancedMarker(position: CLLocationCoordinate2D(latitude: 47.6089945, longitude: -122.3410462))
}()

let marker: GMSMarker = {
GMSMarker(position: CLLocationCoordinate2D(latitude: 47.6089945, longitude: -122.3410462))
}()

func addMarker() {
  if mapView.mapCapabilities.contains(.advancedMarkers) {
      advancedMarker.map = mapView
    } else {
      marker.map = mapView
    }
}

extension MapCapabilities: GMSMapViewDelegate {
  func mapView(_ mapView: GMSMapView, didChangeMapCapabilities mapCapabilities: GMSMapCapabilityFlags) {

     let advancedMarkerAvailable = mapCapabilities.contains(.advancedMarkers)

     advancedMarker.map = advancedMarkerAvailable ? mapView : nil
     marker.map = advancedMarkerAvailable ? nil : mapView
  }
}

Objective-C

// ...

_advancedMarker = [GMSAdvancedMarker markerWithPosition:  kSeattleCoordinates];
_fallbackMarker = [GMSMarker markerWithPosition: kSeattleCoordinates];

-   (void)addMarker {

  if (_mapView.mapCapabilities & GMSMapCapabilityFlagsAdvancedMarkers) {
    _advancedMarker.map = _mapView;
    } else {
    _fallbackMarker.map = _mapView;
  }
}

#pragma mark - GMSMapViewDelegate

-   (void)mapView:(GMSMapView *)mapView
    didChangeMapCapabilities:(GMSMapCapabilityFlags)mapCapabilities {
  BOOL advancedMarkersAvailable = mapCapabilities & GMSMapCapabilityFlagsAdvancedMarkers;
  _advancedMarker.map = advancedMarkersAvailable ? _mapView : nil;
  _fallbackMarker.map = advancedMarkersAvailable ? nil : _mapView;
}
