Wenn Sie Füllung und Strich eines Begrenzungspolygons gestalten möchten, verwenden Sie einen Stilabschluss, der GMSPlaceFeature
akzeptiert und einen GMSFeatureStyle
zurückgibt, um Stilattribute zu definieren. Legen Sie dann die Stileigenschaft auf einen Stilabschluss fest, der Stillogik enthält.
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 }
