Opening MapKit pin in Maps - swift

Question

I can't seem to get the final part of Ray Wenderlich's mapkit tutorial to work. I get the pins to display correctly but when I click on the pin, it doesn't open in Maps as I would like it too. Here is the link to the full tutorial (Link)
And here is my code:
import Foundation
import UIKit
import MapKit
import AddressBook
class CroquisMapView: UIViewController, MKMapViewDelegate {
var section : Int?
var index : Int?
#IBOutlet weak var mapView: MKMapView!
let regionRadius: CLLocationDistance = 1000
func centerMapOnLocation(location: CLLocation) {
let coordinateRegion = MKCoordinateRegionMakeWithDistance(location.coordinate,
regionRadius * 2.0, regionRadius * 2.0)
mapView.setRegion(coordinateRegion, animated: true)
}
override func viewDidLoad() {
mapView.delegate = self
let coordenadas = croquisGruposArray[section!].items[index!].coordenadas
let coordenadasArray = coordenadas!.characters.split{$0 == ","}.map(String.init)
guard let lat = NSNumberFormatter().numberFromString(coordenadasArray[0])?.doubleValue,
let long = NSNumberFormatter().numberFromString(coordenadasArray[1])?.doubleValue else {
return
}
let initialLocation = CLLocation(latitude: lat, longitude: long)
let artwork = Artwork(title: "\(croquisGruposArray[section!].items[index!].descripcion!)",
locationName: "\(globalLigaNombre!)",
discipline: "Futbol",
coordinate: CLLocationCoordinate2D(latitude: lat, longitude: long))
mapView.addAnnotation(artwork)
centerMapOnLocation(initialLocation)
}
}
class Artwork: NSObject, MKAnnotation {
let title: String?
let locationName: String
let discipline: String
let coordinate: CLLocationCoordinate2D
init(title: String, locationName: String, discipline: String, coordinate: CLLocationCoordinate2D) {
self.title = title
self.locationName = locationName
self.discipline = discipline
self.coordinate = coordinate
super.init()
}
var subtitle: String? {
return locationName
}
func mapItem() -> MKMapItem {
let addressDictionary = [String(kABPersonAddressStreetKey): locationName]
let placemark = MKPlacemark(coordinate: coordinate, addressDictionary: addressDictionary)
let mapItem = MKMapItem(placemark: placemark)
mapItem.name = title
return mapItem
}
func mapView(mapView: MKMapView!, annotationView view: MKAnnotationView!, calloutAccessoryControlTapped control: UIControl!) {
print("CLICKED")
let location = view.annotation as! Artwork
let launchOptions = [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]
location.mapItem().openInMapsWithLaunchOptions(launchOptions)
}
}
extension CroquisMapView {
// 1
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView? {
if let annotation = annotation as? Artwork {
let identifier = "pin"
var view: MKPinAnnotationView
if let dequeuedView = mapView.dequeueReusableAnnotationViewWithIdentifier(identifier)
as? MKPinAnnotationView { // 2
dequeuedView.annotation = annotation
view = dequeuedView
} else {
// 3
view = MKPinAnnotationView(annotation: annotation, reuseIdentifier: identifier)
view.canShowCallout = true
view.calloutOffset = CGPoint(x: -5, y: 5)
view.rightCalloutAccessoryView = UIButton(type: .DetailDisclosure) as UIView
}
return view
}
return nil
}
}

Answer 1

Figured it out: I wasn't calling calloutAccessoryControlTapped in my main class. I added it and it with the code provided by Andrej:
func mapView(mapView: MKMapView, annotationView view: MKAnnotationView, calloutAccessoryControlTapped control: UIControl) {
let url = NSURL(string: "http://maps.apple.com/?q=\(lat),\(long)")
if UIApplication.sharedApplication().canOpenURL(url!) == true {
UIApplication.sharedApplication().openURL(url!)
}
}

Answer 2

You can try this:
let url = NSURL(string: "http://maps.apple.com/?q=44.33833,13.98131")
if UIApplication.sharedApplication().canOpenURL(url!) == true
{
UIApplication.sharedApplication().openURL(url!)
}

Answer 3

You can also do like this:
extension ViewController : MKMapViewDelegate {
func getDirections(){ // Here you can put everything, this function is calling when the user select the dialogue pin's bubble. I propose a code who open the application Map.
guard let selectedPin = selectedPin else { return }
let mapItem = MKMapItem(placemark: selectedPin)
let launchOptions = [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]
mapItem.openInMapsWithLaunchOptions(launchOptions)
}
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView?{
guard !(annotation is MKUserLocation) else { return nil }
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?.pinTintColor = UIColor.orangeColor()
pinView?.canShowCallout = true
let smallSquare = CGSize(width: 30, height: 30)
let button = UIButton(frame: CGRect(origin: CGPointZero, size: smallSquare))
button.setBackgroundImage(UIImage(named: "car"), forState: .Normal)
button.addTarget(self, action: #selector(self.getDirections), forControlEvents: .TouchUpInside)
pinView?.leftCalloutAccessoryView = button
return pinView}
}
