SWIFT version
i made a helper class as HelperLocationManager and added a notification- observer pattern
import UIKit
import CoreLocation
class HelperLocationManager: NSObject {
var locationManager = CLLocationManager()
static let sharedInstance = HelperLocationManager()
var currentLocation :CLLocation?
var notGotUserLocation = true
override init() {
super.init()
var code = CLLocationManager.authorizationStatus()
if code == CLAuthorizationStatus.NotDetermined {
locationManager.requestAlwaysAuthorization()
locationManager.requestWhenInUseAuthorization()
}
locationManager.requestAlwaysAuthorization()
locationManager.requestWhenInUseAuthorization()
locationManager.delegate = self
locationManager.distanceFilter = 100;
}
}
extension HelperLocationManager: CLLocationManagerDelegate{
func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
var locValue = locations.last as! CLLocation
println(locValue)
self.currentLocation = locValue
NSNotificationCenter.defaultCenter().postNotificationName("sendCurrentAddressToViewController", object:self.currentLocation)
notGotUserLocation = false
}
func locationManager(manager: CLLocationManager!, didFailWithError error: NSError!) {
println("Your error is ", error.localizedDescription)
}
}
Now if your Viewcontroller class needs the location then put an observer there
var helperLocation:HelperLocationManager?
in viewDidLoad as
override func viewDidLoad() {
helperLocation = HelperLocationManager()
NSNotificationCenter.defaultCenter().addObserver(self, selector: "getCurrentAddressToViewController:", name: "sendCurrentAddressToViewController", object: nil)
}
//and observer as
func getCurrentAddressToViewController(notification: NSNotification) {
currentLocation = notification.object as? CLLocation
NSNotificationCenter.defaultCenter().removeObserver(self, name: "sendCurrentAddressToViewController", object: nil)
}
//although didUpdateLocation is called multiple times you only get one time location because of removing observer after you get the location.
EDIT: I refractored this helper class so that you dont need to add notificationobserver pattern
class HelperLocationManager: NSObject {
private lazy var locationManager = CLLocationManager()
static let sharedInstance = HelperLocationManager()
var currentLocation :CLLocation?
override init() {
super.init()
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.delegate = self
}
}
extension HelperLocationManager: CLLocationManagerDelegate{
func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
switch status {
case CLAuthorizationStatus.NotDetermined:
locationManager.requestWhenInUseAuthorization()
case CLAuthorizationStatus.Restricted:
PrinterHelper.messagePrinter("Restricted Access to location")
case CLAuthorizationStatus.Denied:
PrinterHelper.messagePrinter("User denied access to location")
case CLAuthorizationStatus.AuthorizedWhenInUse:
if #available(iOS 9.0, *) {
locationManager.requestLocation()
} else {
locationManager.startUpdatingLocation()
}
default:
PrinterHelper.messagePrinter("default authorization")
}
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
let locValue = locations.last
HelperLocationManager.sharedInstance.currentLocation = locValue
locationManager.stopUpdatingLocation()
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
PrinterHelper.errorPrinter(error.localizedDescription)
}
}
View Controller where you need to get user Permission
var helperLocationManager:HelperLocationManager?
in viewDidLoad as
override func viewDidLoad() {
helperLocationManager = HelperLocationManager.sharedInstance
}
And to get the location you need to call the singleton property currentLocation as
if let userCurentLoc = HelperLocationManager.sharedInstance.currentLocation{
//userCurrentLoc is the user Location
}
