GMSNavigationNavInfo

@interface GMSNavigationNavInfo : NSObject

Contains information about the state of navigation

• navState

  The current GMSNavigationNavState for navigation.

  Declaration

  Swift

  var navState: GMSNavigationNavState { get }

  Objective-C

  @property (nonatomic, readonly) GMSNavigationNavState navState;

• currentStep

  Information about the upcoming maneuver step. This is only set if the navState is GMSNavigationNavStateEnroute and will be null otherwise.

  Declaration

  Swift

  var currentStep: GMSNavigationStepInfo? { get }

  Objective-C

  @property (nonatomic, readonly, nullable) GMSNavigationStepInfo *currentStep;

• remainingSteps

  The remaining steps after the current step.

  Declaration

  Swift

  var remainingSteps: [GMSNavigationStepInfo] { get }

  Objective-C

  @property (nonatomic, readonly) NSArray<GMSNavigationStepInfo *> *_Nonnull remainingSteps;

• routeChanged

  Whether the route has changed since the last sent message. A route change may be caused by a reroute, the addition/removal of a waypoint, the user selecting or driving onto an alternate route, or a traffic update.

  Declaration

  Swift

  var routeChanged: Bool { get }

  Objective-C

  @property (nonatomic, readonly) BOOL routeChanged;

• timeToCurrentStepSeconds

  The estimated remaining time in seconds along the route to the current step.

  Declaration

  Swift

  var timeToCurrentStepSeconds: TimeInterval { get }

  Objective-C

  @property (nonatomic, readonly) NSTimeInterval timeToCurrentStepSeconds;

• distanceToCurrentStepMeters

  The estimated remaining distance in meters along the route to the current step .

  Declaration

  Swift

  var distanceToCurrentStepMeters: CLLocationDistance { get }

  Objective-C

  @property (nonatomic, readonly) CLLocationDistance distanceToCurrentStepMeters;

• timeToFinalDestinationSeconds

  The estimated remaining time in seconds to the final destination.

  Declaration

  Swift

  var timeToFinalDestinationSeconds: TimeInterval { get }

  Objective-C

  @property (nonatomic, readonly) NSTimeInterval timeToFinalDestinationSeconds;

• distanceToFinalDestinationMeters

  The estimated remaining distance in meters to the final destination.

  Declaration

  Swift

  var distanceToFinalDestinationMeters: CLLocationDistance { get }

  Objective-C

  @property (nonatomic, readonly) CLLocationDistance distanceToFinalDestinationMeters;

• -roundedTime:

  Returns a time rounded to the nearest minute, with a minimum of one minute.

  This can be useful when displaying route information to users, since it can be confusing to display times such a “0 min”.

  Due to the above, input values to this method should always be positive.

  Declaration

  Swift

  func roundedTime(_ timeSeconds: TimeInterval) -> TimeInterval

  Objective-C

  - (NSTimeInterval)roundedTime:(NSTimeInterval)timeSeconds;

• -roundedDistance:

  Returns a rounded measurement representing the given distance, taking into account user preferences and the recommended distance unit for the route.

  Declaration

  Swift

  func roundedDistance(_ distanceMeters: CLLocationDistance) -> Measurement<UnitLength>

  Objective-C

  - (nonnull NSMeasurement<NSUnitLength *> *)roundedDistance:
      (CLLocationDistance)distanceMeters;

• -instructionsForStep:options:

  The formatted instructions for the given step.

  Declaration

  Swift

  func instructions(forStep stepInfo: GMSNavigationStepInfo, options: GMSNavigationInstructionOptions) -> [NSAttributedString]

  Objective-C

  - (nonnull NSArray<NSAttributedString *> *)
      instructionsForStep:(nonnull GMSNavigationStepInfo *)stepInfo
                  options:(nonnull GMSNavigationInstructionOptions *)options;

• -init

  Unavailable

  Declaration

  Objective-C

  - (null_unspecified instancetype)init NS_UNAVAILABLE;
