Cómo aplicar diseño a un polígono de límite

Selecciona la plataforma: Android iOS JavaScript

Para aplicar diseño al relleno y el trazo de un polígono de límite, usa un cierre de diseño que acepte un GMSPlaceFeature y devuelva un GMSFeatureStyle para definir los atributos de diseño. Luego, establece la propiedad de diseño en un cierre de diseño que contenga la lógica de diseño.

Swift

let options = GMSMapViewOptions()
options.mapID = GMSMapID(identifier: "YOUR_MAP_ID")
options.camera = GMSCameraPosition(latitude: 20.773, longitude: -156.01, zoom: 12)
let mapView = GMSMapView(options: options)

let layer = mapView.featureLayer(of: .locality)

// Define a style with purple
let style = FeatureStyle(fill: .purple.withAlphaComponent(0.5), stroke: .purple, strokeWidth: 3.0)

// Apply the style to a single boundary.
layer.style = { ($0.placeID == "ChIJ0zQtYiWsVHkRk8lRoB1RNPo"/* Hana, HI */) ? style : nil }

Objective-C

GMSMapViewOptions *options = [[GMSMapViewOptions alloc] init];
options.camera = [GMSCameraPosition cameraWithLatitude:20.773 longitude:-156.01 zoom:12];
options.mapID = [GMSMapID mapIDWithIdentifier:@"MAP_ID"];
GMSMapView *mapView = [[GMSMapView alloc] initWithOptions:options];

GMSFeatureLayer<GMSPlaceFeature *> *layer = [mapView featureLayerOfFeatureType:GMSFeatureTypeLocality];

// Define a style with purple fill and border.
GMSFeatureStyle *style = [GMSFeatureStyle styleWithFillColor:[[UIColor purpleColor] colorWithAlphaComponent:0.5] strokeColor:[UIColor purpleColor] strokeWidth:3.0];

// Apply the style to a single boundary.
layer.style = ^(GMSPlaceFeature *feature) {
  return [feature.placeID isEqual:@"ChIJ0zQtYiWsVHkRk8lRoB1RNPo"/* Hana, HI */] ? style : nil;
};
