CLLocationManager-Singleton-Swift
import MapKit
protocol LocationUpdateProtocol {
func locationDidUpdateToLocation(location : CLLocation)
}
/// Notification on update of location. UserInfo contains CLLocation for key "location"
let kLocationDidChangeNotification = "LocationDidChangeNotification"
class UserLocationManager: NSObject, CLLocationManagerDelegate {
static let SharedManager = UserLocationManager()
private var locationManager = CLLocationManager()
var currentLocation : CLLocation?
var delegate : LocationUpdateProtocol!
private override init () {
super.init()
self.locationManager.delegate = self
self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
self.locationManager.distanceFilter = kCLLocationAccuracyHundredMeters
locationManager.requestAlwaysAuthorization()
self.locationManager.startUpdatingLocation()
}
// MARK: - CLLocationManagerDelegate
func locationManager(manager: CLLocationManager, didUpdateToLocation newLocation: CLLocation, fromLocation oldLocation: CLLocation) {
currentLocation = newLocation
let userInfo : NSDictionary = ["location" : currentLocation!]
dispatch_async(dispatch_get_main_queue()) { () -> Void in
self.delegate.locationDidUpdateToLocation(self.currentLocation!)
NSNotificationCenter.defaultCenter().postNotificationName(kLocationDidChangeNotification, object: self, userInfo: userInfo as [NSObject : AnyObject])
}
}
}
##Usage:
In your view-controller, do the initialization
let LocationMgr = UserLocationManager.SharedManager
LocationMgr.delegate = self
Implement the proctocol - LocationUpdateProtocol
// MARK: - LocationUpdateProtocol
func locationDidUpdateToLocation(location: CLLocation) {
currentLocation = location
print(currentLocation)
}
or you can choose to receive the notifications
NSNotificationCenter.defaultCenter().addObserver(self, selector: "locationUpdateNotification:", name: kLocationDidChangeNotification, object: nil)
Also add the following Keys to your info.plist
