NavigationMapViewDelegate

public protocol NavigationMapViewDelegate : AnyObject, UnimplementedLogging

The NavigationMapViewDelegate provides methods for configuring the NavigationMapView, as well as responding to events triggered by the NavigationMapView.

Supplying Route Line(s) Data


                    
                    
                    navigationMapView(_:routeLineLayerWithIdentifier:sourceIdentifier:)

Default implementation

Asks the receiver to return a LineLayer for the route line, given a layer identifier and a source identifier. This method is invoked when the map view loads and any time routes are added.

Seealso

CarPlayManagerDelegate.carPlayManager(_:routeLineLayerWithIdentifier:sourceIdentifier:for:), NavigationViewControllerDelegate.navigationViewController(_:routeLineLayerWithIdentifier:sourceIdentifier:).

Default Implementation

UnimplementedLogging prints a warning to standard output the first time this method is called.

Declaration

Swift

func navigationMapView(_ navigationMapView: NavigationMapView, routeLineLayerWithIdentifier identifier: String, sourceIdentifier: String) -> LineLayer?

Parameters

`navigationMapView`	The `NavigationMapView` object.
`identifier`	The `LineLayer` identifier.
`sourceIdentifier`	Identifier of the source, which contains the route data that this method would style.

Return Value

A LineLayer that is applied to the route line.

Default implementation

Asks the receiver to return a LineLayer for the casing layer that surrounds route line, given a layer identifier and a source identifier. This method is invoked when the map view loads and any time routes are added.

Default implementation

Asks the receiver to return a LineLayer for highlighting restricted areas portions of the route, given a layer identifier and a source identifier. This method is invoked when showsRestrictedAreasOnRoute is enabled, the map view loads and any time routes are added.

Default Implementation

UnimplementedLogging prints a warning to standard output the first time this method is called.

Declaration

Swift

func navigationMapView(_ navigationMapView: NavigationMapView, routeRestrictedAreasLineLayerWithIdentifier identifier: String, sourceIdentifier: String) -> LineLayer?

Parameters

`navigationMapView`	The `NavigationMapView` object.
`identifier`	The `LineLayer` identifier.

                    navigationMapView(_:shapeFor:)

Default implementation

Asks the receiver to return an LineString that describes the geometry of the route. Resulting LineString will then be styled using NavigationMapView.navigationMapView(_:routeLineLayerWithIdentifier:sourceIdentifier:) provided style or a default congestion style if above delegate method was not implemented.

Default Implementation

UnimplementedLogging prints a warning to standard output the first time this method is called.

Declaration

Swift

func navigationMapView(_ navigationMapView: NavigationMapView, shapeFor route: Route) -> LineString?

Parameters

`navigationMapView`	The `NavigationMapView`.
`route`	The route that the sender is asking about.

Return Value

A LineString object that defines the shape of the route, or nil in case of default behavior.

                    navigationMapView(_:casingShapeFor:)

Default implementation

Asks the receiver to return an LineString that describes the geometry of the route casing. Resulting LineString will then be styled using NavigationMapView.navigationMapView(_:routeCasingLineLayerWithIdentifier:sourceIdentifier:) provided style or a default style if above delegate method was not implemented.

Default Implementation

UnimplementedLogging prints a warning to standard output the first time this method is called.

Declaration

Swift

func navigationMapView(_ navigationMapView: NavigationMapView, casingShapeFor route: Route) -> LineString?

Parameters

`navigationMapView`	The `NavigationMapView`.
`route`	The route that the sender is asking about.

Return Value

                    navigationMapView(_:restrictedAreasShapeFor:)

Default implementation

Asks the receiver to return an LineString that describes the geometry of the route restricted areas. Resulting LineString will then be styled using NavigationMapView.navigationMapView(_:routeRestrictedAreasLineLayerWithIdentifier:sourceIdentifier:) provided style or a default style if above delegate method was not implemented.

Default Implementation

UnimplementedLogging prints a warning to standard output the first time this method is called.

Declaration

Swift

func navigationMapView(_ navigationMapView: NavigationMapView, restrictedAreasShapeFor route: Route) -> LineString?

Parameters

`navigationMapView`	The `NavigationMapView`.
`route`	The route that the sender is asking about.

Return Value
