Directions on pin not showing up on Swift 3

[dtnguy72]

Hello,

I just converted the code to Swift 3 and unable to see the directions when clicking on the selected pin nor does the image of the car show up.

func getDirections(){
if let selectedPin = selectedPin {
let mapItem = MKMapItem(placemark: selectedPin)
let launchOptions = [MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving]
mapItem.openInMapsWithLaunchOptions(launchOptions)
}
}
The func getDirections is in the Viewcontroller.swift but it doesn't show up on the simulator. Is there a way to get it to work?

Thanks

Try this. I got mine to work:

extension ViewController : MKMapViewDelegate {

func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView?{

    guard !(annotation is MKUserLocation) else { return nil }

    let reuseId = "pin"

    if let pinView = mapView.dequeueReusableAnnotationView(withIdentifier: reuseId) as? MKPinAnnotationView {

        return pinView

    } else {

        let pinView = MKPinAnnotationView(annotation: annotation, reuseIdentifier: reuseId)

        pinView.pinTintColor = UIColor.orange
        pinView.canShowCallout = true
        let smallSquare = CGSize(width: 30, height: 30)
        let button = UIButton(frame: CGRect(origin: CGPoint.zero, size: smallSquare))
        button.setBackgroundImage(UIImage(named: "car"), for: UIControlState())
        button.addTarget(self, action: #selector(ViewController.getDirections), for: .touchUpInside)
        pinView.leftCalloutAccessoryView = button

        return pinView
    }
}

}
