How can I add a button to MKPointAnnotation and open Maps? - ios

Question

I would have to add a button for my particular point of entry , where I click to open the Maps app already passing the coordinates of the selected point. Does anyone know how to do? my code is this. The image is what I would have.
My code:
import Foundation
import UIKit
import MapKit
import CoreLocation
class PuntiVenditaController: UIViewController, MKMapViewDelegate {
#IBOutlet weak var menuButton:UIBarButtonItem!
#IBOutlet weak var mapView: MKMapView!
let regionRadius: CLLocationDistance = 1000
let locationManager = CLLocationManager()
override func viewDidLoad() {
super.viewDidLoad()
if revealViewController() != nil {
menuButton.target = revealViewController()
menuButton.action = "revealToggle:"
view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())
}
locationManager.requestWhenInUseAuthorization()
locationManager.startUpdatingLocation()
let location = CLLocationCoordinate2D(latitude: 41.225891, longitude: 16.291489)
let span = MKCoordinateSpanMake(0.05, 0.05)
let region = MKCoordinateRegion(center: location, span: span)
mapView.setRegion(region, animated: true)
mapView.showsPointsOfInterest = false
mapView.showsUserLocation = true
displayMarkers()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func centerMapOnLocation(location: CLLocation) {
let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate,
regionRadius * 2.0, regionRadius * 2.0)
mapView.setRegion(coordinateRegion, animated: true)
}
func mapView(mapView: MKMapView!, annotationView view: MKAnnotationView!, calloutAccessoryControlTapped control: UIControl!) {
if control == view.rightCalloutAccessoryView{
println(view.annotation.title) // annotation's title
println(view.annotation.subtitle) // annotation's subttitle
//Perform a segue here to navigate to another viewcontroller
// On tapping the disclosure button you will get here
}
}
func mapView(mapView: MKMapView!, viewForAnnotation annotation: MKAnnotation!) -> MKAnnotationView! {
println("viewForannotation")
if annotation is MKUserLocation {
//return nil
return nil
}
let reuseId = "pin"
var pinView = mapView.dequeueReusableAnnotationViewWithIdentifier(reuseId) as? MKPinAnnotationView
if pinView == nil {
//println("Pinview was nil")
pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)
pinView!.canShowCallout = true
pinView!.animatesDrop = true
}
var button = UIButton.buttonWithType(UIButtonType.DetailDisclosure) as! UIButton // button with info sign in it
pinView?.rightCalloutAccessoryView = button
return pinView
}
func displayMarkers() -> Void
{
let annotationView = MKAnnotationView()
// Adding button here wont do anything so remove these two lines
let detailButton: UIButton = UIButton.buttonWithType(UIButtonType.DetailDisclosure) as! UIButton
annotationView.rightCalloutAccessoryView = detailButton
// For adding button we have to use a method named as viewForAnnotation
let annotation = MKPointAnnotation()
let name = "Title"
let latitude = 41.225891
let longitude = 16.291489
annotation.title = name
var markerLatitude: Double = latitude
var markerLongitude: Double = longitude
let location = CLLocationCoordinate2D(latitude: markerLatitude, longitude: markerLongitude)
annotation.coordinate = location
annotation.subtitle = "Subtitle"
mapView.addAnnotation(annotation)
}
}

You can open an URL to open the Maps App at a specific point/address:

But I don't think, you can design a custom marker within the Maps App
