I am using map in Two viewcontrollers
Initially in first viewcontroller i am getting current location in map..
in second viewcontroller i am getting new location coordinates, which i am sending to firstview controller using delegate.. but here how to replace the delegate method coordinates with current location coordinates in first view controller
first view controller code: here in delegate method i am successfully having new location coordinates which i need replace with current location
in userDidEnterInformationdelegate method i am getting all values from 2nd view controller
import UIKit
import CoreLocation
import MapKit
class ProfileAddressViewController: UIViewController, CLLocationManagerDelegate, UISearchBarDelegate, DataEnteredDelegate {
var coordinate: CLLocationCoordinate2D = CLLocationCoordinate2D()
let locationManager = CLLocationManager()
var latitude: Double?
var logitude: Double?
@IBOutlet weak var mapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
self.locationManager.requestAlwaysAuthorization()
if CLLocationManager.locationServicesEnabled() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyNearestTenMeters
locationManager.startUpdatingLocation()
}
}
func userDidEnterInformation(info: DataEnteredModelSave) {
print("map address viewcontroller data \(info)")
self.pincodeField.text = info.pinCode
self.cityField.text = info.cityField
self.latitude = info.zLatitude
self.self.logitude = info.zLongitude
print("new map address viewcontroller data info lat long \(self.latitude) \(self.logitude)")
}
@IBAction func submitButtonClicked(_ sender: UIButton) {
self.view.endEditing(true)
let viewController = self.storyboard?.instantiateViewController(withIdentifier: "NewZoomAddressViewController") as! NewZoomAddressViewController;
self.navigationController?.pushViewController(viewController, animated: true);
}
func locationManager(_ manager: CLLocationManager, didFailWithError error: Error) {
print(error)
}
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
guard let _: CLLocationCoordinate2D = manager.location?.coordinate else { return }
let userLocation :CLLocation = locations.last! as CLLocation
latitude = userLocation.coordinate.latitude
logitude = userLocation.coordinate.longitude
let geocoder = CLGeocoder()
geocoder.reverseGeocodeLocation(userLocation) { (placemarks, error) in
if (error != nil){
print("error in reverseGeocode")
}
let placemark = placemarks! as [CLPlacemark]
if placemark.count>0{
let placemark = placemarks![0]
let placemarkDictonary: NSDictionary=placemark.addressDictionary as! NSDictionary
self.pincodeField.text=placemarkDictonary["ZIP"] as? String
self.cityField.text=placemarkDictonary["City"] as? String
}
}
let center = CLLocationCoordinate2D(latitude: latitude!, longitude: logitude!)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
mapView.setRegion(region, animated: true)
let myAnnotation: MKPointAnnotation = MKPointAnnotation()
myAnnotation.coordinate = CLLocationCoordinate2DMake(userLocation.coordinate.latitude, userLocation.coordinate.longitude);
myAnnotation.title = "Current location"
mapView.addAnnotation(myAnnotation)
}
}
please help me to add delegate method latitude and longitude in locationManager didUpdateLocations
Replace userDidEnterInformation with below code:
func userDidEnterInformation(info: DataEnteredModelSave) {
print("map address viewcontroller data \(info)")
self.pincodeField.text = info.pinCode
self.streetField.text = info.streetField
self.cityField.text = info.cityField
self.latitude = info.zLatitude
self.logitude = info.zLongitude
print("map address viewcontroller data info lat long \(self.latitude) \(self.logitude)")
locationManager.stopUpdatingLocation() //stop updating location when you got data from delegate
let userLocation = CLLocation.init(latitude: latitude!, longitude: logitude!)
let geocoder = CLGeocoder()
geocoder.reverseGeocodeLocation(userLocation) { (placemarks, error) in
if (error != nil){
print("error in reverseGeocode")
}
let placemark = placemarks! as [CLPlacemark]
if placemark.count>0{
let placemark = placemarks![0]
print(placemark.locality!)
print(placemark.administrativeArea!)
print(placemark.country!)
let placemarkDictonary: NSDictionary=placemark.addressDictionary as! NSDictionary
self.pincodeField.text=placemarkDictonary["ZIP"] as? String
self.cityField.text=placemarkDictonary["City"] as? String
self.plotField.text=placemarkDictonary["Name"] as? String
self.streetField.text=placemarkDictonary["Street"] as? String
self.appormentNoField.text=placemarkDictonary["SubThoroughfare"] as? String
self.colonyField.text=placemarkDictonary["SubLocality"] as? String
self.landmarkField.text=placemarkDictonary["SubThoroughfare"] as? String
}
}
let center = CLLocationCoordinate2D(latitude: latitude!, longitude: logitude!)
//Assign data to map again with new location
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
mapView.setRegion(region, animated: true)
let myAnnotation: MKPointAnnotation = MKPointAnnotation()
myAnnotation.coordinate = CLLocationCoordinate2DMake(latitude!, logitude!)
myAnnotation.title = "Current location"
mapView.addAnnotation(myAnnotation)
}
I have added comments please check them.
EDIT: As per your second request if you want to show new coordinates on NewZoomAddressViewController first you need to pass coordinates to NewZoomAddressViewController in submitButtonClicked method like:
viewController.latestLocation = CLLocation.init(latitude: self.latitude!, longitude: self.logitude!)
then in NewZoomAddressViewController declare new var
var latestLocation: CLLocation?
and remove other code which is related to user's current location and final code will look like:
import UIKit
import MapKit
import CoreLocation
//import SwiftKeychainWrapper

func userDidEnterInformation(info: DataEnteredModelSave)
