使用google maps sdk swift创建标记

import UIKit
import GoogleMaps

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 创建地图视图
        let camera = GMSCameraPosition.camera(withLatitude: 37.7749, longitude: -122.4194, zoom: 12.0)
        let mapView = GMSMapView.map(withFrame: CGRect.zero, camera: camera)
        mapView.isMyLocationEnabled = true
        view = mapView
        
        // 创建标记对象
        let marker = GMSMarker()
        marker.position = CLLocationCoordinate2D(latitude: 37.7749, longitude: -122.4194)
        marker.title = "San Francisco"
        marker.icon = GMSMarker.markerImage(with: .blue)
        marker.map = mapView
    }
}
