Turn-by-turn UI

NavigationViewController is a fully-featured user interface for turn-by-turn navigation. Do not confuse it with the NavigationController class in UIKit.

You initialize a navigation view controller based on a predefined Route and NavigationOptions. As the user progresses along the route, the navigation view controller shows their surroundings and the route line on a map. Banners above and below the map display key information pertaining to the route. A list of steps and a feedback mechanism are accessible via the navigation view controller.

To be informed of significant events and decision points as the user progresses along the route, set the NavigationService.delegate property of the NavigationService that you provide when creating the navigation options.

CarPlayNavigationViewController manages the corresponding user interface on a CarPlay screen.

The NavigationViewControllerDelegate protocol provides methods for configuring the map view shown by a NavigationViewController and responding to the cancellation of a navigation session.

For convenience, several location-related methods in the NavigationServiceDelegate protocol have corresponding methods in this protocol.

A route voice controller monitors turn-by-turn navigation events and triggers playing spoken instructions as audio using the Speech Synthesis framework, also known as VoiceOver.

You initialize a voice controller using a NavigationService instance. The voice controller observes when the navigation service hints that the user has passed a spoken instruction point and responds by calling it’s speechSynthesizer to handle the vocalization.

If you want to use your own custom SpeechSynthesizing implementation - also pass it during initialization. If no implementation is provided - MultiplexedSpeechSynthesizer will be used by default.

You can also subclass RouteVoiceController to implement you own mechanism of monitoring navgiation events and calling speechSynthesizer.

Protocol for implementing speech synthesizer to be used in RouteVoiceController.

The SpeechSynthesizingDelegate protocol defines methods that allow an object to respond to significant events related to spoken instructions.

SpeechSynthesizing implementation, using MapboxSpeech framework. Uses pre-caching mechanism for upcoming instructions.

SpeechSynthesizing implementation, using AVSpeechSynthesizer.

SpeechSynthesizingimplementation, aggregating other implementations, to allow ‘fallback’ mechanism. Can be initialized with array of synthesizers which will be called in order of appearance, until one of them is capable to vocalize current SpokenInstruction

A error type returned when encountering errors in the speech engine.

The speech-related action that failed.

Enum used for indicating the type of error occured while speaking an instruction.

Customization options for the turn-by-turn navigation user experience in a NavigationViewController.

A navigation options object is where you place customized components that the navigation view controller uses during its lifetime, such as styles or voice controllers. You would likely use this class if you need to specify a Mapbox access token programmatically instead of in the Info.plist file.

A view that represents the root view of the MapboxNavigation drop-in UI.
