Core Navigation Logic

A NavigationService is the entry-point protocol for MapboxCoreNavigation. It contains all the dependencies needed by the MapboxNavigation UI SDK, as well as dependencies for its child objects. MapboxNavigationService is the default implementation. If you would like to implement your own core-navigation stack, be sure to conform to this protocol.

A NavigationService is the entry-point interface into MapboxCoreNavigation. This service manages a locationManager (which feeds it location updates), a Directions service (for rerouting), a Router (for route-following), a NavigationEventsManager (for telemetry), and a simulation engine for use during poor GPS conditions.

A RouteController tracks the user’s progress along a route, posting notifications as the user reaches significant points along the route. On every location update, the route controller evaluates the user’s location, determining whether the user remains on the route. If not, the route controller calculates a new route.

RouteController is responsible for the core navigation logic whereas NavigationViewController is responsible for displaying a default drop-in navigation UI.

RouteProgress stores the user’s progress along a route.

RouteLegProgress stores the user’s progress along a route leg.

RouteStepProgress stores the user’s progress along a route step.
