  • The VBDClockDirectionFormatter class provides properly formatted descriptions of headings relative to the user, known as clock positions. For example, a value of 90 may be formatted as “3 o’clock”, depending on the locale.

    Use this class to create localized heading strings when displaying directions relative to the user’s current location and heading. To format a direction irrespective of the user’s orientation, use VBDCompassDirectionFormatter instead.

    Declaration

    Objective-C

    @interface VBDClockDirectionFormatter : NSFormatter

  • The VBDCompassDirectionFormatter class provides properly formatted descriptions of absolute headings. For example, a value of 90 may be formatted as “east”, depending on the locale.

    Use this class to create localized heading strings when displaying directions irrespective of the user’s current location. To format a direction relative to the user’s current location, use VBDCompassDirectionFormatter instead.

    Declaration

    Objective-C

    struct VBDCoordinateBounds {}

  • Returns YES if the two coordinate bounds are equal to each other.

    Declaration

    Objective-C

    static inline BOOL
VBDCoordinateBoundsEqualToCoordinateBounds(VBDCoordinateBounds bounds1,
                                           VBDCoordinateBounds bounds2)

  • Returns the area spanned by the coordinate bounds.

    Declaration

    Objective-C

    static inline VBDCoordinateSpan
VBDCoordinateBoundsGetCoordinateSpan(VBDCoordinateBounds bounds)

  • Returns YES if the coordinate bounds covers no area.

    Note

    A bounds may be empty but have a non-zero coordinate span (e.g., when its northeast point lies due north of its southwest point).

    Declaration

    Objective-C

    static inline BOOL VBDCoordinateBoundsIsEmpty(VBDCoordinateBounds bounds)

  • Creates a new VBDCoordinateBounds structure from the given southwest and northeast coordinates.

    Declaration

    Objective-C

    static inline VBDCoordinateBounds
VBDCoordinateBoundsMake(CLLocationCoordinate2D sw, CLLocationCoordinate2D ne)

  • Returns a coordinate bounds with southwest and northeast coordinates that are offset from those of the source bounds.

    Declaration

    Objective-C

    static inline VBDCoordinateBounds
VBDCoordinateBoundsOffset(VBDCoordinateBounds bounds, VBDCoordinateSpan offset)

  • Defines the area spanned by an VBDCoordinateBounds.

    Declaration

    Objective-C

    struct VBDCoordinateSpan {}

  • Returns YES if the two coordinate spans represent the same latitudinal change and the same longitudinal change.

    Declaration

    Objective-C

    static inline BOOL
VBDCoordinateSpanEqualToCoordinateSpan(VBDCoordinateSpan span1,
                                       VBDCoordinateSpan span2)

  • Creates a new VBDCoordinateSpan from the given latitudinal and longitudinal deltas.

    Declaration

    Objective-C

    static inline VBDCoordinateSpan
VBDCoordinateSpanMake(CLLocationDegrees latitudeDelta,
                      CLLocationDegrees longitudeDelta)

  • An area of zero width and zero height.

    Declaration

    Objective-C

    extern const VBDCoordinateSpan VBDCoordinateSpanZero

  • Returns degrees, converted from radians.

    Declaration

    Objective-C

    static inline CLLocationDegrees VBDDegreesFromRadians(CGFloat radians)

  • Returns radians, converted from degrees.

    Declaration

    Objective-C

    static inline CGFloat VBDRadiansFromDegrees(CLLocationDegrees degrees)

  • Returns a formatted string for the given coordinate bounds.

    Declaration

    Objective-C

    static inline NSString *_Nonnull VBDStringFromCoordinateBounds(
    VBDCoordinateBounds bounds)

  • The VBDCoordinateFormatter class provides properly formatted descriptions of geographic coordinate pairs. Use this class to create localized coordinate strings when displaying location information to users.
