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 }
