How do I detect Tap and Hold on a pin in MKMapView? - mkmapview

Question

The title says it all. I'm trying to detect a tap on a pin in a MKMapView and I don't even know where to begin. Its not an UIView, so I can't add a gesture recognizer and I can't find a UIView in MKPlaceMark to add it.

You're question is not very clear but you can do like this:
import UIKit
import MapKit
protocol HandleMapSearch: class {
func dropPinZoomIn(placemark:MKPlacemark)
}
class ViewController: UIViewController {
func getDirections(){
// Here you can put anythings like:
guard let selectedPin = selectedPin else { return }
let mapItem = MKMapItem(placemark: selectedPin)
let launchOptions = [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]
mapItem.openInMapsWithLaunchOptions(launchOptions)
}
}
extension ViewController : MKMapViewDelegate {
func mapView(mapView: MKMapView, viewForAnnotation annotation: MKAnnotation) -> MKAnnotationView?{
guard !(annotation is MKUserLocation) else { 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() // The pin's color
pinView?.canShowCallout = true // To set dialogue bubbles of the pin.
let smallSquare = CGSize(width: 30, height: 30)
let button = UIButton(frame: CGRect(origin: CGPointZero, size: smallSquare)) // To initialize the button in the dialogue bubbles of the pin.
button.addTarget(self, action: #selector(ViewController.getDirections), forControlEvents: .TouchUpInside) // To set and initialize the button.
pinView?.leftCalloutAccessoryView = button
return pinView
}
}
