如何在谷歌地图iOS软件开发工具包上显示用户位置

import GoogleMaps

class ViewController: UIViewController, CLLocationManagerDelegate {

    var mapView: GMSMapView!
    var locationManager: CLLocationManager!

    override func viewDidLoad() {
        super.viewDidLoad()
        
        // 初始化地图视图
        mapView = GMSMapView(frame: view.bounds)
        mapView.mapType = .normal
        view.addSubview(mapView)
        
        // 请求用户位置权限
        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.requestWhenInUseAuthorization()
    }
    
    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        if status == .authorizedWhenInUse {
            // 获取用户当前位置
            locationManager.startUpdatingLocation()
            
            // 在地图上显示用户位置
            mapView.isMyLocationEnabled = true
            mapView.settings.myLocationButton = true
        }
    }
    
    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.first {
            // 将地图的camera设置为用户当前位置
            let camera = GMSCameraPosition.camera(withTarget: location.coordinate, zoom: 15)
            mapView.camera = camera
            
            // 停止更新用户位置
            locationManager.stopUpdatingLocation()
        }
    }
}
