Swift 2 – Can't get user location with CLLocationManager

问题

Here is my VC code:

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {
    @IBOutlet weak var mapView: MKMapView!
    let locationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

        locationManager.delegate = self
        locationManager.requestWhenInUseAuthorization()
        mapView.showsUserLocation = true
    }

    func locationManager(manager: CLLocationManager, didChangeAuthorizationStatus status: CLAuthorizationStatus) {
        mapView.showsUserLocation = (status == .AuthorizedAlways)
    }

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let locValue:CLLocationCoordinate2D = manager.location!.coordinate
        print("locations = \(locValue.latitude) \(locValue.longitude)")
    }
}

I have also added NSLocationWhenInUseUsageDescription in my plist file. And I have the CoreLocation and MapKit frameworks, any idea why this is not working? It doesn't show the user location on the map nor does it print out the user's coordinates. Haven't found anything online on on stack overflow.

This works for me

Swift 2 - (Xcode 7.2.1)

ViewController.swift


import UIKit
import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

    var locationManager: CLLocationManager = CLLocationManager()

    override func viewDidLoad() {
        super.viewDidLoad()

        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.delegate = self
        locationManager.requestWhenInUseAuthorization()
        locationManager.startUpdatingLocation()
    }

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {

        self.locationManager.stopUpdatingLocation()

        let latestLocation = locations.last

        let latitude = String(format: "%.4f", latestLocation!.coordinate.latitude)
        let longitude = String(format: "%.4f", latestLocation!.coordinate.longitude)

        print("Latitude: \(latitude)")
        print("Longitude: \(longitude)")
    }
}

info.plist

Add a new line

Information Property List: NSLocationWhenInUseUsageDescription

Type: String

Value: The application uses this information to show you your location

回答2:

Try getting the location by getting the last object for the array locations in the method locationManager(_:,didUpdateLocations locations: [CLLocations]) .

Something like this:

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
        let locValue:CLLocationCoordinate2D = locations.last!
        print("locations = \(locValue.latitude) \(locValue.longitude)")
}

回答3:

you have to use these location access permission in your plist.

NSLocationAlwaysAndWhenInUseUsageDescription
NSLocationWhenInUseUsageDescription

you are not using always and in InUse permiossion

Note by Apple:

This app has attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain both NSLocationAlwaysAndWhenInUseUsageDescription and NSLocationWhenInUseUsageDescription keys with string values explaining to the user how the app uses this data
