MapKit en Swift, Parte 2

core-location cllocationmanager

Question

Estoy intentando trabajar con Map Kit en Swift. Intento mostrar el área en el mapa, un pin (MKPinAnnotationView) y la posición actual. Todos se muestran bien. Intento agregar el botón de divulgación e interceptar el tapping sobre él. Se agregó el botón de divulgación, pero no funciona interceptando el tapping.

pinPressed con el método de calloutAccessoryControlTapped no funciona ....

Este es un código de muestra:

import UIKit
import MapKit
import CoreLocation

class ViewController: UIViewController, MKMapViewDelegate, CLLocationManagerDelegate {

@IBOutlet weak var mainMapView: MKMapView!

var locationManager = CLLocationManager()

override func viewDidLoad() {
    super.viewDidLoad()

    locationManager.delegate = self
    locationManager.desiredAccuracy = kCLLocationAccuracyBest
    locationManager.requestAlwaysAuthorization()
    locationManager.startUpdatingLocation()

    var objectLatitude = 53.204526
    var objectLongitude = 50.111751

    var currentLatitude = 53.203715
    var currentLongitude =  50.160374

    var latDelta = 0.05
    var longDelta = 0.05

    var currentLocationSpan: MKCoordinateSpan = MKCoordinateSpanMake(latDelta, longDelta)
    var currentLocation: CLLocationCoordinate2D = CLLocationCoordinate2DMake(locationManager.location.coordinate.latitude, locationManager.location.coordinate.longitude)
    var currentRegion: MKCoordinateRegion = MKCoordinateRegionMake(currentLocation, currentLocationSpan)
    self.mainMapView.setRegion(currentRegion, animated: true)

    var objectLocation: CLLocationCoordinate2D = CLLocationCoordinate2DMake(objectLatitude, objectLongitude)
    var objectAnnotation = MKPointAnnotation()
    objectAnnotation.coordinate = objectLocation
    objectAnnotation.title = "St. George''s Church"
    objectAnnotation.subtitle = "Church of the Great Martyr St. George"
    self.mainMapView.addAnnotation(objectAnnotation)
}

func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {

        if annotation is MKUserLocation {
            //return nil so map view draws "blue dot" for standard user location
            return nil
        }

        let reuseId = "pin"

        var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) as? MKPinAnnotationView
        if pinView == nil {
            pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
            pinView!.canShowCallout = true
            pinView!.animatesDrop = true
            pinView!.pinColor = .Purple
            pinView!.rightCalloutAccessoryView = UIButton.buttonWithType(.DetailDisclosure) as UIButton
        }
        else {
            pinView!.annotation = annotation
        }
        return pinView
}

func pinPressed(mapView: MKMapView!, annotationView: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {

    if control == annotationView.rightCalloutAccessoryView {
        println("Disclosure Pressed!")
    }
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}
}

Answer 1

El método de delegado calloutAccessoryControlTapped se debe mapView(annotationView:calloutAccessoryControlTapped:) .

No puede usar su propio nombre como pinPressed(...) .

Esto se aplica a cualquier método delegado y está dictado por el protocolo.

Entonces debería ser:

func mapView(mapView: MKMapView!, annotationView: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {

    if control == annotationView.rightCalloutAccessoryView {
        println("Disclosure Pressed!")
    }
}

Answer 2

Solo calloutAccessoryControlTapped actualizando el método de delegado calloutAccessoryControlTapped , porque lo intento hoy (06/09/2015) y no funciona. Este campo de entrada cambió: annotationView view: MKAnnotationView!

//Click on left or right button
func mapView(mapView: MKMapView!, annotationView view: MKAnnotationView!, calloutAccessoryControlTapped control: UIControl!)
{
    let anotation = view.annotation as! MyAnnotation

    if (control == view.rightCalloutAccessoryView)
    {
        println("Button right pressed!")
    }
    else if (control == view.leftCalloutAccessoryView)
    {
        println("Button left pressed!")
    }
}
