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; }
