  • The property indicates whether the user’s position is actually on the map. Setting this property will update the view of the current position visible on the map.

    Declaration

    Objective-C

    @property (nonatomic, strong) TTTrackingObject *_Nonnull currentPosition;

    Swift

    var currentPosition: TTTrackingObject { get set }

  • Add tracking object to the map.

    Declaration

    Objective-C

    - (void)addTrackingObject:(TTTrackingObject *_Nonnull)trackingObject;

    Swift

    func add(_ trackingObject: TTTrackingObject)

    Parameters

    trackingObject

    trackingObject

  • Remove tracking object from the map.

    Declaration

    Objective-C

    - (void)removeTrackingObject:(TTTrackingObject *_Nonnull)trackingObject;

    Swift

    func remove(_ trackingObject: TTTrackingObject)

    Parameters

    trackingObject

    trackingObject

  • Start tracking the specific object. In the tracking mode, rotate and pan gestures are blocked. The user can change only zoom level, map camera is automatically adjusted to follow the tracking object.

    Declaration

    Objective-C

    - (void)startTrackingObject:(TTTrackingObject *_Nonnull)trackingObject;

    Swift

    func start(_ trackingObject: TTTrackingObject)

    Parameters

    trackingObject

    trackingObject

  • Stop tracking object, all gestures are enabled again.

    Declaration

    Objective-C

    - (void)stopTrackingObject:(TTTrackingObject *_Nonnull)trackingObject;

    Swift

    func stop(_ trackingObject: TTTrackingObject)

    Parameters

    trackingObject

    tracking object

  • Update position of tracking object.

    Declaration

    Objective-C

    - (void)updateTrackingObject:(TTTrackingObject *_Nonnull)trackingObject
              withTTLocation:(id)location;

    Swift

    func update(_ trackingObject: TTTrackingObject, withTTLocation location: Any!)

    Parameters

    trackingObject

    Tracking Object
    location

    TTLocation object

  • Enable low-pass filtering so that the camera can follow the chevron in a more smoother way.

    Declaration

    Objective-C

    - (void)setBearingSmoothingFilter:(unsigned int)smoothFactor;

    Swift

    func setBearingSmoothingFilter(_ smoothFactor: UInt32)

    Parameters

    smoothFactor

    smooth Factor - describes the strength of smoothing

  • Sets the tracking screen coordinates to a given point.

    Declaration

    Objective-C

    - (void)setTrackingScreenCoordinates:(CGPoint)point;

    Swift

    func setTrackingScreenCoordinates(_ point: CGPoint)

    Parameters

    point

    The point that will be used to center the tracking object.

  • The default tracking object that describes the current position on the map.

    Declaration

    Objective-C

    + (TTTrackingObject *_Nonnull)defaultCurrentPosition;

    Swift

    static func defaultCurrentPosition() -> TTTrackingObject

    Return Value

    TTTrackingObject.
