Questions tagged [nsdateformatter]

Class that creates string representations of NSDate (and NSCalendarDate) objects, and convert textual representations of dates and times into NSDate objects.

There are many attributes you can get and set on a 10.4-style date formatter, including the locale, time zone, calendar, format string, and the various textual strings like the month names. You are encouraged, however, not to change individual settings. Instead you should accept the default settings established on initialization and specify the format using setDateStyle:, setTimeStyle:, and appropriate style constants.
