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，但我无法获得用户的位置。我在NSLocationWhenInUseUsageDescriptation中添加了info.plist。有人可以帮我吗？我很长一段时间都在尝试这个。

我在这些方面遇到错误。

=================================
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＆＃39; MKMapView＆＃39;没有会员＆＃39; myLocationEnabled＆＃39; 2类型的价值＆＃39; MKMapView＆＃39;没有会员的设置＆＃39; 3无法指定类型＆＃39; GMSCameraPosition的值！＆＃39;输入＆＃39; MKMapCamera＆＃39;

这是我得到的3个错误

我的确切错误是在@IBOutlet弱var mapView：MKMapView！我改变了这个@IBOutlet弱var mapView：GMSMapView！我得到线程1错误@IBOutlet弱var mapView：MKMapView！在这个唯一的地图展示中，但没有固定我的位置

Answer 1

您正在声明MKMapView的实例（MapKit Framework提供的mapView）。您应该使用GMSMapView的实例（Google Maps Framework的地图）来使用这些功能。

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");
}
