usage - Swift 2 CLLocationManager Error al actualizar

startupdatinglocation swift

Question

Actualicé Xcode 6 a Xcode 7 beta con Swift 2. Recibo este error y no puedo descubrir cómo solucionarlo, por favor, ayúdeme. Gracias. Este es mi código:

 func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
    let location = locations.last as! CLLocation

    let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
    let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))

    self.map.setRegion(region, animated: true)
}

y me sale este error:

Objective-C method ''locationManager:didUpdateLocations:'' provided by method ''locationManager(_:didUpdateLocations:)'' conflicts with optional requirement method ''locationManager(_:didUpdateLocations:)'' in protocol ''CLLocationManagerDelegate''

Answer 1

Acabo de tener el mismo problema que tú, cambiar.

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

a

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

Haga clic en su proyecto: vaya a Crear fases-> Vincular binarios con bibliotecas y agregue CoreLocation.framework

import CoreLocation

class ViewController: UIViewController, CLLocationManagerDelegate {

let locationManager = CLLocationManager()
var LatitudeGPS = NSString()
var LongitudeGPS = NSString()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    updateLocation()

func updateLocation() {
    self.locationManager.delegate = self
    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest
    //self.locationManager.distanceFilter = 10
    self.locationManager.requestWhenInUseAuthorization()
    self.locationManager.startUpdatingLocation()
}

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

    locationManager.stopUpdatingLocation() // Stop Location Manager - keep here to run just once

    LatitudeGPS = String(format: "%.6f", manager.location!.coordinate.latitude)
    LongitudeGPS = String(format: "%.6f", manager.location!.coordinate.longitude)
    print("Latitude - /(LatitudeGPS)")

}

Este es mi código que funciona en xcode 7, también tuve que limpiar mi código (Producto-> Limpiar)

Answer 3

Resolví esto mediante el siguiente código:

//CLLocationManagerDelegate
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
    let location:CLLocation = locations[locations.count-1] as! CLLocation 

    if (location.horizontalAccuracy > 0) {
        self.locationManager.stopUpdatingLocation()
        print(location.coordinate, terminator: "")
        updateWeatherInfo(location.coordinate.latitude, longitude: location.coordinate.longitude)
    }
}

Answer 4

@objc marcar su clase o método con el atributo @objc . Entonces, o bien:

@objc class MyManagerDelegate: NSObject, CLLocationManagerDelegate {

    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
        ...
    }

}

O:

class MyManagerDelegate: CLLocationManagerDelegate {

    @objc func locationManager(manager: CLLocationManager, didUpdateLocations locations: [AnyObject]) {
        ...
    }

}

Answer 5

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    let location = locations.last as! CLLocation!
    manager.stopUpdatingLocation()
    let region = MKCoordinateRegion(center: CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude), span: MKCoordinateSpan(latitudeDelta: 0.001, longitudeDelta: 0.001))
    mapView.setRegion(region, animated: true)
}
