У меня есть проблема, которую я не могу решить.Я пытаюсь получить текущее местоположение, чтобы обновить вид карты и центрировать камеру, но когда я закрываю контроллер вида и запускаю новый контроллер Mapview, «текущее местоположение» показывает неправильное местоположение, рядом с моим положением, но не текущим местоположением.Кто-нибудь может мне помочь?это мой код:
class MapContainerViewController: UIViewController{
@IBOutlet weak var mapView: GMSMapView!
var locationManager = CLLocationManager()
var myLocation: CLLocation?
var autorizeChange: Bool?
var geofire: GeoFire?
var createGeoforme: Bool?
var INITIAL_CENTER: CLLocation?
var searchCircle: GMSCircle?
var timer = Timer()
override func viewDidLoad() {
super.viewDidLoad()
autorizeChange = true
checkLocationServices()
createGeoforme = false
mapView.delegate = self
// Do any additional setup after loading the view.
}
func setupLocationManager(){
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.distanceFilter = 100
locationManager.pausesLocationUpdatesAutomatically = false
locationManager.startMonitoringSignificantLocationChanges()
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
}
func checkLocationServices(){
if CLLocationManager.locationServicesEnabled(){
setupLocationManager()
checkLocationAutorization()
} else {
}
}
func checkLocationAutorization(){
switch CLLocationManager.authorizationStatus() {
case .authorizedWhenInUse:
//Do map stuff
if (mapView.isMyLocationEnabled == false ){
mapView.isMyLocationEnabled = true
mapView.settings.myLocationButton = true
var ref: DatabaseReference
ref = Database.database().reference()
geofire = GeoFire(firebaseRef: ref)
}
break
case .denied:
//Show alert instructing
break
case .notDetermined:
//location manager
locationManager.requestWhenInUseAuthorization()
break
case .restricted:
//Show alert letting them know
break
case .authorizedAlways:
break
default:
}
}
}
}
