Class

MKDirections.Request

The start and end points of a route, along with the planned mode of transportation.

Declaration

class Request : NSObject

Overview

You use an MKDirections.Request object when requesting or providing directions. If your app provides directions, use this class to decode the URL sent to you by Maps. If you need to request directions from Apple, pass an instance of this class to an MKDirections object. For example, an app that provides subway directions might request walking directions to and from relevant subway stations.

For apps that provide directions, you receive direction-related URLs in your app delegate’s application(_:open:sourceApplication:annotation:) method. Upon receiving a URL, call the isDirectionsRequest(_:) method of this class to determine if the URL is related to routing directions. If it is, create an instance of this class using the provided URL and extract the map items associated with the start and end points.
