MGLClockDirectionFormatter
@interface MGLClockDirectionFormatter : NSFormatter
The MGLClockDirectionFormatter
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 MGLCompassDirectionFormatter
instead.
