AKLocationManager

AKLocationManager is class which can better controll your location.

Features

• Detect first location.

• Better error management.

Usage

Standalone

var locationManager: AKLocationManager!

override func viewDidLoad() {
    super.viewDidLoad()

    locationManager = AKLocationManager()
    locationManager.startUpdatingLocationWithRequest()
}

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)

    locationManager.stopUpdatingLocation()
}

With google maps

var locationManager: AKLocationManager! {
    didSet { locationManagerger.delegate = self }
}
var mapView: GMSMapView!

//  MARK: - Life cycle

override func viewDidLoad() {
    super.viewDidLoad()

    locationManager = AKLocationManager()

    mapView = GMSMapView()
    mapView.alpha = 0
    mapView.frame = view.frame

    view.addSubview(mapView)
    view.sendSubviewToBack(mapView)

    locationManager.addObserver(mapView, forKeyPath: "myLocation")
    locationManager.requestForUpdatingLocation()
    mapView.myLocationEnabled = true
    locationManager.startUpdatingLocation()
}

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)

    locationManager.stopUpdatingLocation()
}

//  MARK: - AKLocationManagerDelegate

extension DemoViewController: AKLocationManagerDelegate {
    func locationManager(manager: AKLocationManager, didGetFirstLocation location: CLLocation) {
        mapView.camera = GMSCameraPosition.cameraWithLatitude(location.coordinate.latitude, longitude: location.coordinate.longitude, zoom: 12)
        mapView.alpha = 1
    }
}

Before enable my location with myLocationEnabled property from GMSMapView class, call requestForUpdatingLocation() method.

  Represents as AKLocationManagerRequestType:

  • .WhenInUse : Equal requestWhenInUseAuthorization() method. Read more on Apple Developer
  • .Always : Equal requestAlwaysAuthorization() method. Read more on Apple Developer

Initiating Standard Location Updates

 func startUpdatingLocation()

Starts the generation of updates that report the user’s current location.

func startUpdatingLocationWithRequest(requestType: AKLocationManagerRequestType)

Starts the generation of updates that report the user’s current location with requests permission to use location services.

 func stopUpdatingLocation()

Stops the generation of location updates.

func requestLocation()

Request the one-time delivery of the user’s current location.

Observerving custom location manager

func addObserver(target: AnyObject, forKeyPath keyPath: String)

Registers an observer to receive KVO notifications for the specified key-path relative to the receiver.

Parameters:

• target : The object to register for KVO notifications.
• keyPath : The key path, relative to the receiver, of the property to observe. This value must not be nil.

func removeObserver()

Stops a given object from receiving change notifications for the property specified by a given key-path relative to the receiver.

Getting Recently Retrieved Data

var myLocation: CLLocation? {get}

The most recently retrieved user location. (read-only). The value of this property is nil if no location data has ever been retrieved.

Configurate

var updateSpeed: CLLocationSpeed

Specifies the speed in meters per second, when location must be updated not less that updateLocationTimeInterval minimum property.

Example:

• 0 : Stand
• 0.3 - 1.4 : Walk
• 1.4 - 4 : Run
• 4 - 12 : Bicycle

The initial value of this property is 0.4 meters per second. Walk.

var updateLocationTimeInterval: AKLocationManagerTimeInterval

Specifies the minimum and maximum update time intervar in secounds. Updating location will be no earlier than minimum time interval value with condition: "current speed more or equal to updateSpeed property and not equal zero". But if the condition is not satisfied, updating location will be no earlier than maximum time interval value. The initial value of this property is 5.0 seconds for minimum time interval and 300.0 seconds for maximum.

var firstLocationAttempts: Int

Specifies the count of attempts when location manager will try to get first location. One attempt every second. When all attempts is over, location manager will return error .LocationManagerCantDetectFirstLocation with error protocol method: func locationManager(manager: AKLocationManager, didGetError error: AKLocationManagerError). The initial value of this property is 5 attempts.
