Um Füllung und Strich eines Begrenzungspolygons zu gestalten, müssen Sie einen Stilabschluss verwenden, der GMSPlaceFeature
akzeptiert und einen GMSFeatureStyle
zurückgibt, um Stilattribute zu definieren. Legen Sie dann für die Stileigenschaft einen Stilabschluss fest, der eine 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 }
Objective-C

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; };
