MGLCompassDirectionFormatter

@interface MGLCompassDirectionFormatter : NSFormatter

The MGLCompassDirectionFormatter 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 MGLClockDirectionFormatter instead.
