swift get directions in maps app

Question

I have an app that displays multiple locations in multiple mapviews. How can I add a button that allows the user to open one of these locations in their maps app and to get directions to it?

Answer 1

If you got an MKPlaceMark you can use an MKMapItem and open the Map-app with the location as launchOption:

var mapItem = MKMapItem(placemark: yourPlaceMark)

mapItem.name = "The way I want to go"

//You could also choose: MKLaunchOptionsDirectionsModeWalking
var launchOptions = [MKLaunchOptionsDirectionsModeKey : MKLaunchOptionsDirectionsModeDriving]

mapItem.openInMapsWithLaunchOptions(launchOptions)

Swift 3

mapItem.openInMaps(launchOptions: launchOptions)
