在iOS谷歌地图应用程序上定义闭合多边形,可以通过以下步骤实现:
示例代码如下:
import GoogleMaps
class ViewController: UIViewController {
var mapView: GMSMapView!
override func viewDidLoad() {
super.viewDidLoad()
// 创建地图视图
let camera = GMSCameraPosition.camera(withLatitude: 37.7749, longitude: -122.4194, zoom: 12.0)
mapView = GMSMapView.map(withFrame: view.bounds, camera: camera)
view.addSubview(mapView)
// 添加多边形
let path = GMSMutablePath()
path.add(CLLocationCoordinate2D(latitude: 37.785834, longitude: -122.406417))
path.add(CLLocationCoordinate2D(latitude: 37.758859, longitude: -122.404058))
path.add(CLLocationCoordinate2D(latitude: 37.766845, longitude: -122.451599))
path.add(CLLocationCoordinate2D(latitude: 37.789988, longitude: -122.467654))
path.add(CLLocationCoordinate2D(latitude: 37.785834, longitude: -122.406417))
let polygon = GMSPolygon(path: path)
polygon.fillColor = UIColor(red: 0.25, green: 0, blue: 0, alpha: 0.2)
polygon.strokeColor = .black
polygon.strokeWidth = 2
polygon.map = mapView
}
}
这样就在iOS谷歌地图应用程序上定义了一个闭合多边形。你可以根据需要添加更多的顶点坐标来定义不同形状的多边形。
