Question

¿Cómo obtener una dirección de coordenadas usando MapKit?

Tengo este código cuando presiono largo en el mapa obtiene las coordenadas:

func didLongPressMap(sender: UILongPressGestureRecognizer) {

    if sender.state == UIGestureRecognizerState.Began {
        let touchPoint = sender.locationInView(self.mapView)
        let touchCoordinate = self.mapView.convertPoint(touchPoint, toCoordinateFromView: self.mapView)
        var annotation = MKPointAnnotation()
        annotation.coordinate = touchCoordinate
        annotation.title = "Your position"
        self.mapView.addAnnotation(annotation) //drops the pin
        println("lat:  /(touchCoordinate.latitude)")
        var num = (touchCoordinate.latitude as NSNumber).floatValue
        var formatter = NSNumberFormatter()
        formatter.maximumFractionDigits = 4
        formatter.minimumFractionDigits = 4
        var str = formatter.stringFromNumber(num)
        println("long: /(touchCoordinate.longitude)")
        var num1 = (touchCoordinate.longitude as NSNumber).floatValue
        var formatter1 = NSNumberFormatter()
        formatter1.maximumFractionDigits = 4
        formatter1.minimumFractionDigits = 4
        var str1 = formatter1.stringFromNumber(num1)
        self.adressLoLa.text = "/(num),/(num1)"
                }
}

y quiero imprimir en annotation.title la dirección completa (calle, ciudad, código postal, país).

Answer 1

SWIFT 4.0: EDITAR

MapKit framework proporciona una forma de obtener detalles de direcciones a partir de las coordenadas.

Necesita usar geocodificación inversa del kit de mapas. CLGeocoder clase CLGeocoder se usa para obtener la ubicación de la dirección y la dirección desde la ubicación (coordenadas). El método reverseGeocodeLocation devolverá los detalles de la dirección de las coordenadas.

Este método acepta CLLocation como parámetro y devuelve CLPlacemark , que contiene el diccionario de direcciones.

Entonces el método anterior se actualizará como:

@objc func didLongPressMap(sender: UILongPressGestureRecognizer) {

    if sender.state == UIGestureRecognizerState.began {
        let touchPoint = sender.location(in: mapView)
        let touchCoordinate = mapView.convert(touchPoint, toCoordinateFrom: self.mapView)
        let annotation = MKPointAnnotation()
        annotation.coordinate = touchCoordinate
        annotation.title = "Your position"
        mapView.addAnnotation(annotation) //drops the pin
        print("lat:  /(touchCoordinate.latitude)")
        let num = touchCoordinate.latitude as NSNumber
        let formatter = NumberFormatter()
        formatter.maximumFractionDigits = 4
        formatter.minimumFractionDigits = 4
        _ = formatter.string(from: num)
        print("long: /(touchCoordinate.longitude)")
        let num1 = touchCoordinate.longitude as NSNumber
        let formatter1 = NumberFormatter()
        formatter1.maximumFractionDigits = 4
        formatter1.minimumFractionDigits = 4
        _ = formatter1.string(from: num1)
        self.adressLoLa.text = "/(num),/(num1)"

        // Add below code to get address for touch coordinates.
        let geoCoder = CLGeocoder()
        let location = CLLocation(latitude: touchCoordinate.latitude, longitude: touchCoordinate.longitude)
        geoCoder.reverseGeocodeLocation(location, completionHandler: { (placemarks, error) -> Void in

            // Place details
            var placeMark: CLPlacemark!
            placeMark = placemarks?[0]

            // Location name
            if let locationName = placeMark.location {
                print(locationName)
            }
            // Street address
            if let street = placeMark.thoroughfare {
                print(street)
            }
            // City
            if let city = placeMark.subAdministrativeArea {
                print(city)
            }
            // Zip code
            if let zip = placeMark.isoCountryCode {
                print(zip)
            }
            // Country
            if let country = placeMark.country {
                print(country)
            }
        })
    }
}

Answer 2

Actualiza Swift 4

addressDictionary quedó en deprecated en iOS 11.0

let geoCoder = CLGeocoder()
let location = CLLocation(latitude: 37.769193, longitude: -122.426512)
geoCoder.reverseGeocodeLocation(location, completionHandler: { (placemarks, error) -> Void in

// Place details
var placeMark: CLPlacemark!
placeMark = placemarks?[0]

// Complete address as PostalAddress
print(placeMark.postalAddress as Any)  //  Import Contacts

// Location name
if let locationName = placeMark.name  {
    print(locationName)
}

// Street address
if let street = placeMark.thoroughfare {
   print(street)
}

// Country
if let country = placeMark.country {
   print(country)
}
})

Más datos pueden ser recuperados

nombre, vía, subThoroughfare, localidad, subLocality, administrativeArea, subAdministrativeArea, código postal, isoCountryCode, country, inlandWater, areaOfInterest

Answer 3

En el método didUpdateToLocation:

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:
    (CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
    CLLocation *location = [locationManager location];


    CLLocationCoordinate2D coordinate = [location coordinate];


    latitude = [NSString stringWithFormat:@"%.12f", coordinate.latitude];
    longitude = [NSString stringWithFormat:@"%.12f", coordinate.longitude];

    CLLocation *location1 = [[CLLocation alloc]
                             initWithLatitude:latitude.floatValue
                             longitude:longitude.floatValue];

    self.myGeocoder = [[CLGeocoder alloc] init];

    [self.myGeocoder
     reverseGeocodeLocation:location1
     completionHandler:^(NSArray *placemarks, NSError *error) {
        if (error == nil &&
             [placemarks count] > 0){
            placemark = [placemarks lastObject];
            NSString*    vendorLocation=[NSString stringWithFormat:@"%@ %@",
                                          placemark.locality,
                                          placemark.subLocality];
            NSLog(@"%@",vendorLocation);
        }
    }];
}

Answer 4

Gracias a @Kampai por su respuesta, la revisé un poco para que funcione con Swift 1.2 :

        var geocoder = CLGeocoder()
        var location = CLLocation(latitude: IC.coordinate!.latitude, longitude: IC.coordinate!.longitude)
        geocoder.reverseGeocodeLocation(location) {
            (placemarks, error) -> Void in
            if let placemarks = placemarks as? [CLPlacemark] where placemarks.count > 0 {
                var placemark = placemarks[0]
                println(placemark.addressDictionary)
        }

Resultado:

[SubLocality: Sydney, calle: 141 Harrington Street, estado: NSW, SubThoroughfare: 141, CountryCode: AU, ZIP: 2000, calle: Harrington Street, nombre: 141 Harrington Street, país: Australia, líneas de dirección formateadas: ("141 Harrington Street" , "The Rocks NSW 2000", Australia), Ciudad: The Rocks]

Answer 5

Gracias a @Kampi por esto. Esta es una versión actualizada de Swift 2.0 (Xcode 7):

func setUsersClosestCity()
{
    let geoCoder = CLGeocoder()
    let location = CLLocation(latitude: _point1.coordinate.latitude, longitude: _point1.coordinate.longitude)
    geoCoder.reverseGeocodeLocation(location)
    {
        (placemarks, error) -> Void in

        let placeArray = placemarks as [CLPlacemark]!

        // Place details
        var placeMark: CLPlacemark!
        placeMark = placeArray?[0]

        // Address dictionary
        print(placeMark.addressDictionary)

        // Location name
        if let locationName = placeMark.addressDictionary?["Name"] as? NSString
        {
            print(locationName)
        }

        // Street address
        if let street = placeMark.addressDictionary?["Thoroughfare"] as? NSString
        {
            print(street)
        }

        // City
        if let city = placeMark.addressDictionary?["City"] as? NSString
        {
            print(city)
        }

        // Zip code
        if let zip = placeMark.addressDictionary?["ZIP"] as? NSString
        {
            print(zip)
        }

        // Country
        if let country = placeMark.addressDictionary?["Country"] as? NSString
        {
            print(country)
        }
    }
}

Answer 6

Gracias a la respuesta de @ Kampai , aquí hay una forma compatible y segura de Swift 3 (¡sin forzar ! ):

let geoCoder = CLGeocoder()
let location = CLLocation(latitude: touchCoordinate.latitude, longitude: touchCoordinate.longitude)

geoCoder.reverseGeocodeLocation(location, completionHandler: { placemarks, error in
    guard let addressDict = placemarks?[0].addressDictionary else {
        return
    }

    // Print each key-value pair in a new row
    addressDict.forEach { print($0) }

    // Print fully formatted address
    if let formattedAddress = addressDict["FormattedAddressLines"] as? [String] {
        print(formattedAddress.joined(separator: ", "))
    }

    // Access each element manually
    if let locationName = addressDict["Name"] as? String {
        print(locationName)
    }
    if let street = addressDict["Thoroughfare"] as? String {
        print(street)
    }
    if let city = addressDict["City"] as? String {
        print(city)
    }
    if let zip = addressDict["ZIP"] as? String {
        print(zip)
    }
    if let country = addressDict["Country"] as? String {
        print(country)
    }
})

No se olvide de NSLocationWhenInUseUsageDescription y NSLocationAlwaysUsageDescription claves de NSLocationAlwaysUsageDescription en Swift 3

Answer 7

Para Swift 3: y Swift 4

Primero, debe establecer la asignación para recibir el GPS del usuario en info.plist .

Set: NSLocationWhenInUseUsageDescription con una cadena aleatoria. Y / o: NSLocationAlwaysUsageDescription con una cadena aleatoria.

Luego configuré una clase para obtener los datos deseados, como zip, ciudad, país ...:

import Foundation
import MapKit

typealias JSONDictionary = [String:Any]

class LocationServices {

    let shared = LocationServices()
    let locManager = CLLocationManager()
    var currentLocation: CLLocation!

    let authStatus = CLLocationManager.authorizationStatus()
    let inUse = CLAuthorizationStatus.authorizedWhenInUse
    let always = CLAuthorizationStatus.authorizedAlways

    func getAdress(completion: @escaping (_ address: JSONDictionary?, _ error: Error?) -> ()) {

        self.locManager.requestWhenInUseAuthorization()

        if self.authStatus == inUse || self.authStatus == always {

            self.currentLocation = locManager.location

            let geoCoder = CLGeocoder()

            geoCoder.reverseGeocodeLocation(self.currentLocation) { placemarks, error in

                if let e = error {

                    completion(nil, e)

                } else {

                    let placeArray = placemarks as? [CLPlacemark]

                    var placeMark: CLPlacemark!

                    placeMark = placeArray?[0]

                    guard let address = placeMark.addressDictionary as? JSONDictionary else {
                        return
                    }

                    completion(address, nil)

                }

            }

        }

    }

}

Llamado por:

import UIKit

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        LocationServices.shared.getAdress { address, error in

            if let a = address, let city = a["City"] as? String {
               //
            }

        }

    }

}

Hecho

Answer 8

func placePicker(_ viewController: GMSPlacePickerViewController, didPick place: GMSPlace) {

    viewController.dismiss(animated: true, completion: nil)
    let geoCoder = CLGeocoder()
    let location = CLLocation(latitude: place.coordinate.latitude, longitude: place.coordinate.longitude)
    geoCoder.reverseGeocodeLocation(location, completionHandler: { (placemarks, error) -> Void in

        // Place details
        var placeMark: CLPlacemark!
        placeMark = placemarks?[0]

        // Address dictionary
        print(placeMark.addressDictionary as Any)
   // 

    print("Place name /(place.name)")
    print("Place address /(String(describing: place.formattedAddress))")
    print("Place attributions /(String(describing: place.attributions))")



})
}

use este código, esto resolverá el problema.
