How to Stop getting the users location in MapBox - ios

Question

How can you stop getting the user location when using CLLocationManager and mapbox?
I have a application that does the following:
1) Gets the users current location with the CLLocationManager and then calls the command ".stopUpdatingLocation()" which stops getting the user location.
2) Creates a map with mapbox
As soon as the application has both, it does NOT stop getting the user location.
I tested the application in the each separate scenarios (option 1 above alone and option 2 alone) and it successfully stop getting the user location but when the application has both implemented it does NOT stop getting the user location.
viewController.swift:
import UIKit
import MapboxGL
import CoreLocation
class ViewController: UIViewController, MGLMapViewDelegate , CLLocationManagerDelegate {
//MARK: - Properties
var manager: CLLocationManager?
private var currentLocation: CLPlacemark?
private var currLocLatitude:CLLocationDegrees?

//MARK: - Lifecycle

manager?.startUpdatingLocation()
}

func getLocationInfo(placemark: CLPlacemark) {
currentLocation = placemark //will delete later - redudant
currLocLatitude = placemark.location.coordinate.latitude
currLocLongitude = placemark.location.coordinate.longitude
currLocTitle = placemark.areasOfInterest[0] as? String
currLocSubtitle = placemark.locality
//DEBUGGING

Answer 1

You are calling the manager returned in the function, try call self.manager.stopUpdatingLocation()

Answer 2

Resolved this issue by getting the user location inside the "ViewDidLoad" method and creating the map inside the "ViewDidAppear" method
By having them seperated, it seems to have resolve the problem.
import UIKit
import CoreLocation
import MapboxGL
class AViewController: UIViewController, CLLocationManagerDelegate {
var manager:CLLocationManager!
var userLocation:CLLocation!
override func viewDidLoad() {
super.viewDidLoad()
getUserLocation()
}//eom
override func viewDidAppear(animated: Bool) {
createMapBoxMap()
}
/*getting user current location*/
func getUserLocation(){
self.manager = CLLocationManager()
self.manager.delegate = self
self.manager.desiredAccuracy = kCLLocationAccuracyBest
self.manager.requestWhenInUseAuthorization()
self.manager.startUpdatingLocation()
}//eom
/*location manager 'didUpdateLocations' function */
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
self.manager.stopUpdatingLocation() //stop getting user location
println(locations)
self.userLocation = locations[0] as! CLLocation
}//eom
/*Create preliminary map */
func createMapBoxMap(){
// set your access token
let mapView = MGLMapView(frame: view.bounds, accessToken: "pk.eyJ1IjoiZGFya2ZhZGVyIiwiYSI6IlplVDhfR3MifQ.pPEz732qS8g0WEScdItakg")
mapView.autoresizingMask = .FlexibleWidth | .FlexibleHeight
// set the map's center coordinate
mapView.setCenterCoordinate(CLLocationCoordinate2D(latitude: self.userLocation.coordinate.latitude, longitude: self.userLocation.coordinate.longitude),
zoomLevel: 13, animated: false)
view.addSubview(mapView)
//showing the user location on map - blue dot
mapView.showsUserLocation = true
}//eom
