Location manager show bad location in gmsMapView swift 4.2 - swift

Question

I have a problem that a I cannot resolve. I'm trying to get the current location to update the mapview and center the camera, but when I close the view controller and init a new Mapviewcontroller the "current location" show a location incorrect, near to my position but not the current location. Can anyone guide me o help me? this is my code:
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:
}
}
}
}
extension MapContainerViewController: GMSMapViewDelegate{
func mapView(_ mapView: GMSMapView, idleAt position: GMSCameraPosition)
{
mapView.clear()
let coordinate = mapView.projection.coordinate(for: mapView.center)
var cooordinate2d = CLLocationCoordinate2D.init(latitude: coordinate.latitude, longitude: coordinate.longitude)
var circ = GMSCircle.init(position: coordinate, radius: zoomLevelToRadius(zoomLevel: Double(position.zoom)))
circ.fillColor = UIColor.init(displayP3Red: 0, green: 255, blue: 255, alpha: 0.15)
circ.strokeColor = UIColor.init(displayP3Red: 0, green: 0, blue: 0, alpha: 0.15)
circ.strokeWidth = 0.5
circ.map = mapView;
}
func zoomLevelToRadius(zoomLevel: Double) -> Double{
// Approximation to fit circle into view
return (16384000/pow(2, zoomLevel))
}
}
extension MapContainerViewController: CLLocationManagerDelegate{
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let userLocation: CLLocation = locations[0]
let location = CLLocationCoordinate2D(latitude: userLocation.coordinate.latitude, longitude: userLocation.coordinate.longitude)
mapView.camera = GMSCameraPosition.camera(withTarget: location, zoom: 14)
let centerLocation = mapView.projection.coordinate(for: mapView.center)
}
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
checkLocationAutorization()
}
}

This sample code can be your solution you can find here https://github.com/SwiftGuides/Google_Place_Picker
This is sample code i wrote for Google place picker to pick exact pin point custom location (not nearby location)
In your case you can apply this too. Just check the example code you will get you solution
