import GoogleMaps

class ViewController: UIViewController {
    var mapView: GMSMapView!
    var mapTypeButton: UIButton!

    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: CGRect.zero, camera: camera)
        mapView.isMyLocationEnabled = true
        view = mapView

        // 创建切换按钮
