Pour styliser le remplissage et le trait d'un polygone de limite, utilisez un style de fermeture qui
accepte un GMSPlaceFeature
et renvoie une
GMSFeatureStyle
pour définir des attributs de style. Définissez ensuite
à une fermeture de style, qui contient une logique de stylisation.
Swift
let mapView = GMSMapView(frame: .zero, mapID: GMSMapID(identifier: "YOUR_MAP_ID"), camera: GMSCameraPosition(latitude: 20.773, longitude: -156.01, zoom: 12)) 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 }
