Core Location to an iOS Framework

Question

I am creating an iOS Framework and i want to use Core Location to interact with Beacons. For testing reasons i am trying to get user location.

This is the class i created in the framework.

import Foundation
import CoreLocation

 public class BeaconManager:NSObject,CLLocationManagerDelegate{

    var locationManager:CLLocationManager = CLLocationManager()

    public override init() {
        super.init()
        locationManager.requestAlwaysAuthorization()
        locationManager.delegate = self
        locationManager.startUpdatingLocation()
    }

     public func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
        if let location = locations.first as? CLLocation {
            println(location)
        }
    }
}

And i am calling it from a test app that has the framework like this

import UIKit
import OtravitaSDK
import CoreLocation

class ViewController: UIViewController {

      var bm = BeaconManager()

    override func viewDidLoad() {
        super.viewDidLoad()


        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}

But is not working , is not printing the location. I have set the NSLocationAlwaysUsageDescription both in framework's info.plist and the app's info.plist

Do you get the request to allow location access? – Paulw11 Sep 16 '15 at 09:35 — Paulw11, Sep 16 '15 at 09:35

you can add your decription in NSLocationAlwaysUsageDescription & NSLocationWhenInUseUsageDescription in plist

This code put into AppDelegate file

     var locationManager:CLLocationManager?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

      //You can give this permission for fetch current location
        var type = UIUserNotificationType.Badge | UIUserNotificationType.Alert | UIUserNotificationType.Sound;
        var setting = UIUserNotificationSettings(forTypes: type, categories: nil);
        UIApplication.sharedApplication().registerUserNotificationSettings(setting);
        UIApplication.sharedApplication().registerForRemoteNotifications();

        locationManager = CLLocationManager()
        locationManager?.requestAlwaysAuthorization()
        locationManager?.delegate = self
        locationManager?.startUpdatingLocation()

        // Override point for customization after application launch.
        return true
    }

    func locationManager(manager: CLLocationManager!, didUpdateLocations locations: [AnyObject]!) {
        if let location = locations.first as? CLLocation {
            println(location)
        }
    }

What you need to do as of iOS 8 is configure your Info.plist file to cater for 2 kinds of location behaviour. You need to supply a default message that appears with a popup by default, asking the user for consent to use their location.

NSLocationWhenInUseUsageDescription and NSLocationAlwaysUsageDescription

See this article for a full walkthrough and another SO post which discusses this topic. Hope this helps!

You can create at first the reporter class (with shared instance) which will implement the CLLocationManagerDelegate, so you could implement your logic inside delegate methods

import Foundation
import CoreLocation

class LocationReporter: NSObject, CLLocationManagerDelegate {

    static let sharedInstance = LocationReporter()

    func startUpdating(locationManager: CLLocationManager) {
        locationManager.delegate = self
        locationManager.requestAlwaysAuthorization()
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.startUpdatingLocation()
    }

    func stopUpdating(locationManager: CLLocationManager) {
        locationManager.stopUpdatingLocation()
    }

    func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        if let location = locations.first {
            print("latitude: ", location.coordinate.latitude)
            print("longitude: ", location.coordinate.longitude)
        }
    }

  //implement other locationManger delegate methods


}

Next you can create a Client class

 import Foundation
 import CoreLocation

 class LocationDetectionClient {

    private let locationManager = CLLocationManager()

    func start() {
        LocationReporter.sharedInstance.startUpdating(locationManager: locationManager)
    }

    func stop() {
        LocationReporter.sharedInstance.stopUpdating(locationManager: locationManager)
    }

}

And finally call the Client methods where you need

let locationDetectionClient = LocationDetectionClient()

public func startLocationDetection() {
    locationDetectionClient.start()
}

public func stopLocationDetection() {
    locationDetectionClient.stop()
}

Hope this would help
