如何使用google api获取用户的位置

Question

import UIKit
import GoogleMaps
import MapKit

class ViewController: UIViewController, CLLocationManagerDelegate, MKMapViewDelegate{

    @IBOutlet weak var mapView: MKMapView!

    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

        locationManager.delegate = self
        locationManager.requestAlwaysAuthorization()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
        if status == .AuthorizedWhenInUse{
            locationManager.startUpdatingLocation()

            mapView.myLocationEnabled = true
            mapView.settings.myLocationButton = true
        }
    }

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.first {


            mapView.camera = GMSCameraPosition(target: location.coordinate, zoom: 15, bearing: 0, viewingAngle: 0)


            locationManager.stopUpdatingLocation()
        }
    }


}

这是我编写的代码，但我无法获取用户的位置。 我在 info.plist 中添加了 NSLocationWhenInUseUsageDescriptation 。 有人可以帮我吗？我已经尝试了很长时间了。

我在这些行中遇到错误。

=================================
mapView.myLocationEnabled = true
mapView.settings.myLocationButton = true

mapView.camera = GMSCameraPosition(target: location.coordinate, zoom: 15, bearing: 0, viewingAngle: 0)

==================================

有人可以帮我解决这个问题吗？

1 类型“MKMapView”的值没有成员“myLocationEnabled” 2 “MKMapView”类型的值没有成员“设置” 3 无法分配类型“GMSCameraPosition！”的值输入“MKMapCamera”

这是我遇到的第三个错误

我的确切错误在@IBOutlet weak var mapView: MKMapView! 我是否更改了此@IBOutlet 弱var mapView：GMSMapView！ 我得到线程 1 错误 @IBOutlet weak var mapView: MKMapView!在这个唯一的地图显示中，但没有固定我的位置

我不会为答案添加评论

Answer 1

您正在声明MKMapView 的实例（由 MapKit 框架提供的 mapView）。为了使用这些功能，您应该使用 GMSMapView 的实例，即 Google Maps Framework 的地图。

Answer 2

我已经这样做了，它就像一个魅力：

let locationManager = CLLocationManager()
var mapView:GMSMapView!

override func viewDidLoad() {
    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()
}


func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

    CLGeocoder().reverseGeocodeLocation(manager.location!, completionHandler: { (placemarks, error) -> Void in

        if(error != nil) {

            print("Error:" + error!.localizedDescription )
            return

        }

        if(placemarks!.count > 0) {

            if let pm = placemarks?.first {
                self.displayLocationInfo(pm)
            }

        } else {
            print("Error with data")
        }

    });

}

func displayLocationInfo(placemark: CLPlacemark) {
    self.locationManager.stopUpdatingLocation()

}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
    print("Error with Server");
}
