Membuat penanda lanjutan

Pilih platform: Android iOS JavaScript

Gunakan subclass GMSAdvancedMarker untuk membuat fitur penanda dasar atau spesifik, seperti yang ditunjukkan di bawah. Sebagai subclass dari GMSMarker, GMSAdvancedMarker memberikan penanda dengan lebih banyak ekspresi.

Swift

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

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

Objective-C

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

GMSMapViewOptions *options = [[GMSMapViewOptions alloc] init];
options.camera = camera;
options.mapID = mapID;
options.frame = self.view.bounds;
self.mapView = [[GMSMapView alloc] initWithOptions:options];

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

Menghapus penanda lanjutan

Serupa dengan GMSMarker, Anda dapat menghapus penanda lanjutan dari peta dengan menetapkan properti peta GMSAdvancedMarker ke nil. Atau, Anda dapat menghapus semua overlay (termasuk penanda lanjutan) di peta dengan memanggil metode GMSMapView clear.

Swift

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

Objective-C

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.8683
                                                        longitude:151.2086
                                                             zoom:6];
GMSMapViewOptions *options = [[GMSMapViewOptions alloc] init];
options.camera = camera;
mapView = [[GMSMapView alloc] initWithOptions:options];
// ...
[mapView clear];

Jika ingin mengubah penanda setelah menambahkannya ke peta, pastikan Anda tetap mempertahankan objek GMSAdvancedMarker. Anda dapat mengubah penanda nanti dengan membuat perubahan pada objek ini.

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;

Kemampuan peta

Properti mapCapabilities di GMSMapView menambahkan pemeriksaan terprogram untuk fitur khusus peta. Hal ini berguna saat ingin mengetahui apakah kemampuan peta tertentu tersedia sebelum memanggil API tertentu. Fungsi didChangeMapCapabilities dari GMSMapViewDelegate juga dipanggil saat kemampuan berubah. Kueri ini menentukan apakah tampilan peta mendukung penanda lanjutan.

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;
}
