Я пытаюсь создать приложение карт с помощью Mapkit. но я не могу получить доступ к синей точке, когда запускаю приложение на симуляторе. Я все еще новичок в Mapkit, и любые советы будут очень признательны. вот мой код. ps: я кодирую с использованием Swift 4.2 и Xcode 11
import UIKit
import MapKit
import CoreLocation
class mapViewController: UIViewController {
let locationManager = CLLocationManager()
@IBOutlet weak var mapView: MKMapView!
override func viewDidLoad() {
super.viewDidLoad()
locationManager.requestWhenInUseAuthorization()
checkLocationServices()
}
func setupLocationManager() {
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
}
func centerViewOnUserLocation() {
if let location = locationManager.location?.coordinate {
let region = MKCoordinateRegion.init(center: location, latitudinalMeters: 10000, longitudinalMeters: 10000)
mapView.setRegion(region, animated: true)
}
}
func checkLocationServices() {
if CLLocationManager.locationServicesEnabled() {
setupLocationManager()
checkLocationAuthorization()
} else {
}
}
func checkLocationAuthorization() {
let pin = MKPointAnnotation()
switch CLLocationManager.authorizationStatus() {
case .authorizedWhenInUse:
mapView.showsUserLocation = true
mapView.addAnnotation(pin)
break
case .denied:
break
case .notDetermined:
locationManager.requestWhenInUseAuthorization()
break
case .restricted:
break
case .authorizedAlways:
break
}
}
}
extension mapViewController: CLLocationManagerDelegate {
func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
// we'll be back
}
func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
//we'll be back
}
}
