TGGeoPolyline


@interface TGGeoPolyline : NSObject

Helper class to contain a polyline geometry for use in -[TGMarker polyline].

Set the geometry of a marker to a polyline along the given coordinates; _coordinates is a pointer to a sequence of _count LngLats; markers can have their geometry set multiple times with possibly different geometry types; returns true if the marker ID was found and successfully updated, otherwise returns false.

  • Inits a TGGeoPolyline and allocate enough memory to hold size geographic coordinates.

    Declaration

    Objective-C

    - (nonnull instancetype)initWithSize:(NSUInteger)size;

    Swift

    init(size: UInt)

  • Adds a geographic coordinate to the polyline.

    Declaration

    Objective-C

    - (void)addPoint:(CLLocationCoordinate2D)point;

    Swift

    func addPoint(_ point: CLLocationCoordinate2D)

    Parameters

    point

    the geographic coordinate to add to this polyline

  • Gets the number of geographic coordinates describing this polyline.

    Declaration

    Objective-C

    - (NSUInteger)count;

    Swift

    func count() -> UInt

    Return Value

    the number of geographic coordinates in this polyline

  • Gets a pointer to the geographic coordinates describing this poyline of array length -[TGGeoPolyline count:].

    Declaration

    Objective-C

    - (nonnull CLLocationCoordinate2D *)coordinates;

    Swift

    func coordinates() -> UnsafeMutablePointer<CLLocationCoordinate2D>

    Return Value

    a pointer to the list of geographic coordinates describing this polyline

  • Removes all coordinates of this polyline.

    Declaration

    Objective-C

    - (void)removeAll;

    Swift

    func removeAll()
