MKDirectionsResponse

The MKDirectionsResponse class provides a container for route information returned by the Apple servers. You do not create instances of this class directly. Instead, you initiate a request for directions between two points by calling the calculateDirectionsWithCompletionHandler: method of an MKDirections object. You receive an instance of this class as the result.

  • The start point of the route. (read-only)

    Declaration

    Swift

    var source: MKMapItem { get }

    Objective-C

    @property(nonatomic, readonly) MKMapItem * _Nonnull source

    Discussion

    The item in this property may contain additional details that were not included in the original item used to create the MKDirectionsRequest object.

    Availability

    Available in iOS 7.0 and later.

  • The end point of the route. (read-only)

    Declaration

    Swift

    var destination: MKMapItem { get }

    Objective-C

    @property(nonatomic, readonly) MKMapItem * _Nonnull destination

    Discussion

    The item in this property may contain additional details that were not included in the original item used to create the MKDirectionsRequest object.

    Availability

    Available in iOS 7.0 and later.

  • An array of route objects representing the directions between the start and end points. (read-only)

    Declaration

    Swift

    var routes: [MKRoute] { get }

    Objective-C

    @property(nonatomic, readonly) NSArray <MKRoute *> * _Nonnull routes

    Discussion

    The array contains one or more MKRoute objects, each of which represents a possible set of directions for the user to follow. If you did not request alternate routes in the original directions request, this array contains at most one object.

    Each route object contains geometry information that you can use to display that route on your app’s map view. Routes may also contain additional information that is relevant to that particular route, such as the expected travel time and any trip advisory notices.

    Availability

    Available in iOS 7.0 and later.
