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.
An array of route objects representing the directions between the start and end points. (read-only)
@property (nonatomic, readonly) NSArray *routes
The array contains one or more
MKRouteobjects, 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.
