境界線ポリゴンの塗りつぶしとストロークをスタイル設定するには、GMSPlaceFeature
を受け取り、GMSFeatureStyle
を返すスタイル設定クロージャを使用して、スタイル属性を定義します。次に、スタイル プロパティを、スタイル設定ロジックを含むスタイル設定クロージャに設定します。
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
