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.
