  • AnnotationPoint überlagert callout

    Hallo,

    kann mir jemand helfen? Mein Map View Controller hat die Aufgabe, eine location in einem callout zu zeigen. Beim draufklicken kommt man auf die map app. Klapp auch. Jetzt ist aber auf dem callout immer noch die annotation vom Typ MKPointAnnotation überlagert. D.h. ich mochte die rote Annotation löschen, und nur den callout angezeigt haben. Wie mache ich das ohne mein Projekt zu zerschießen?

    Quellcode

    1. class MapViewController: UIViewController, MKMapViewDelegate
    2. {
    3. //outlet variable is used for establishing a connection with the map view in the storyboard
    4. @IBOutlet var mapView: MKMapView!
    5. // @IBOutlet var segmentedControl: UISegmentedControl!
    6. var spot = Spot()
    7. let locationManager = CLLocationManager()
    8. var currentPlacemark:CLPlacemark?// it is used to save the selected spot
    9. var currentTransportType = MKDirectionsTransportType.automobile
    10. var currentRoute: MKRoute?// store the current route
    11. override func viewDidLoad()
    12. {
    13. super.viewDidLoad()
    14. // self.navigationItem.backBarButtonItem?.title = " "
    15. navigationItem.backBarButtonItem = UIBarButtonItem(title:"", style: .plain, target: nil, action:nil)
    16. // we want to show the users location
    17. mapView.delegate = self//important
    18. mapView.showsUserLocation = true
    19. //request for a user's authorization for lacation services
    20. locationManager.requestWhenInUseAuthorization()
    21. let status = CLLocationManager.authorizationStatus()
    22. if status == CLAuthorizationStatus.authorizedWhenInUse
    23. {
    24. mapView.showsUserLocation = true
    25. }
    26. let geoCoder = CLGeocoder()
    27. geoCoder.geocodeAddressString(spot.location,
    28. completionHandler:

    30. placemarks, error in
    31. if let error = error

    40. // value of current Placemark
    41. self.currentPlacemark = placemark
    42. // // add annotation
