RouteControllerDelegate Protocol Reference


                    
                    
                    routeController(_:shouldRerouteFrom:)

Returns whether the route controller should be allowed to calculate a new route.

If implemented, this method is called as soon as the route controller detects that the user is off the predetermined route. Implement this method to conditionally prevent rerouting. If this method returns true, routeController(_:willRerouteFrom:) will be called immediately afterwards.

Declaration

Swift

optional func routeController(_ routeController: RouteController, shouldRerouteFrom location: CLLocation) -> Bool

Parameters

`routeController`	The route controller that has detected the need to calculate a new route.
`location`	The user’s current location.

Return Value

True to allow the route controller to calculate a new route; false to keep tracking the current route.

                    routeController(_:willRerouteFrom:)

Called immediately before the route controller calculates a new route.

This method is called after routeController(_:shouldRerouteFrom:) is called, simultaneously with the RouteControllerWillReroute notification being posted, and before routeController(_:didRerouteAlong:) is called.

Declaration

Swift

optional func routeController(_ routeController: RouteController, willRerouteFrom location: CLLocation)

Parameters

`routeController`	The route controller that will calculate a new route.
`location`	The user’s current location.

                    routeController(_:didDiscard:)

Called when a location has been discarded for being inaccurate.

See CLLocation.isQualified for more information about what qualifies a location.

Declaration

Swift

optional func routeController(_ routeController: RouteController, didDiscard location: CLLocation)

Parameters

`routeController`	The route controller that discarded the location.
`location`	The location that was discarded

                    routeController(_:didRerouteAlong:)

Called immediately after the route controller receives a new route.

This method is called after routeController(_:willRerouteFrom:) and simultaneously with the RouteControllerDidReroute notification being posted.

Declaration

Swift

optional func routeController(_ routeController: RouteController, didRerouteAlong route: Route)

Parameters

Called when the route controller fails to receive a new route.

This method is called after routeController(_:willRerouteFrom:) and simultaneously with the RouteControllerDidFailToReroute notification being posted.

Declaration

                    routeController(_:didUpdate:)

Called when the route controller’s location manager receive a location update.

These locations can be modified due to replay or simulation but they can also derive from regular location updates from a CLLocationManager.

Declaration

Swift

optional func routeController(_ routeController: RouteController, didUpdate locations: [CLLocation])

Parameters

`routeController`	The route controller that received the new locations.
`locations`	The locations that were received from the associated location manager.
