In der Kartenansicht kann man sich nicht bewegen swift

Question

Ich kann die Karte nicht verschieben oder an andere Orte zoomen. Ich habe dieses Tutorial verwendet: https://www.youtube.com/watch?v=qrdIL44T6FQ, um meinen Standort in der Karte anzuzeigen. Aus irgendeinem Grund zoomt die Karte zuerst sehr langsam (+ - 30 Sekunden) zu meinem Standort, nachdem ich die App geöffnet habe. Dann, wenn ich mich in der Karte bewegen will, kann ich nicht. Es bleibt an meinem aktuellen Standort.

Hier ist mein Code:

import UIKit 
 
import MapKit 
 
import CoreLocation 
 

 
class FirstViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate { 
 

 
    @IBOutlet weak var mapView: MKMapView! 
 
    
 
    let locationManager = CLLocationManager() 
 
    
 
    override func viewDidLoad() { 
 
     super.viewDidLoad() 
 
     
 
     self.locationManager.delegate = self 
 
     
 
     self.locationManager.desiredAccuracy = kCLLocationAccuracyBest 
 
     
 
     self.locationManager.requestWhenInUseAuthorization() 
 
     
 
     self.locationManager.startUpdatingLocation() 
 
     
 
     self.mapView.showsUserLocation = true 
 
     
 
     
 

 

 
    } 
 

 
    override func didReceiveMemoryWarning() { 
 
     super.didReceiveMemoryWarning() 
 
     // Dispose of any resources that can be recreated. 
 
    } 
 
    
 
    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { 
 
     
 
     let location = locations.last 
 
     
 
     let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude) 
 
     
 
     let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.5, longitudeDelta: 0.5)) 
 
     
 
     self.mapView.setRegion(region, animated: true) 
 
     
 
     self.locationManager.startUpdatingLocation() 
 
    
 
    } 
 
    
 
    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) { 
 
     print("Errors: " + error.localizedDescription) 
 
    } 
 
     
 

 
}

Hat das Problem jemand wissen? Vielen Dank!

Niemals habe ich irgendwo einen Fehler gemacht. Dieser Code funktioniert gut:

import UIKit 
 
import MapKit 
 
import CoreLocation 
 

 
class FirstViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate { 
 

 
    @IBOutlet weak var mapView: MKMapView! 
 
    
 
    let locationManager = CLLocationManager() 
 
    
 
    override func viewDidLoad() 
 
    { 
 
     super.viewDidLoad() 
 
     
 
     self.locationManager.delegate = self 
 
     self.locationManager.desiredAccuracy = kCLLocationAccuracyBest 
 
     self.locationManager.requestWhenInUseAuthorization() 
 
     self.locationManager.startUpdatingLocation() 
 
     
 
     self.mapView.showsUserLocation = true 
 
     
 
    } 
 
    
 
    override func didReceiveMemoryWarning() 
 
    { 
 
     super.didReceiveMemoryWarning() 
 
     // Dispose of any resources that can be recreated. 
 
    } 
 
    
 
    // MARK: - Location Delegate Methods 
 
    
 
    func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) 
 
    { 
 
     let location = locations.last 
 
     
 
     let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude) 
 
     let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 1, longitudeDelta: 1)) 
 
     
 
     self.mapView.setRegion(region, animated: true) 
 
     
 
     self.locationManager.stopUpdatingLocation() 
 
    } 
 
    
 
    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) 
 
    { 
 
     print("Error: " + error.localizedDescription) 
 
    } 
 
    
 
}
