NSDate without time component

• Jason Wiggins NSDate without time component Nov 27 2005, 07:33
  Hi everyone,
  
  I'm a newbie and have checked out the archives but I may not be
  searching for the right thing. Any help would be grateful.
  
  What I'm doing is using an NSDatePicker to return an instance of
  NSDate. All I want from this NSDate is the date, not the time
  component. Or if possible, when NSDatePicker returns the NSDate, the
  time is set to 00:00 UTC. Is this possible?
  
  Thanks
  JayJay

  I would have assumed that calling setDatePickerElements: and leaving
  out the ability the edit time values would normalize the time to
  something sane.
  
  If there's no way of telling the picker to normalize the time for
  you, you could try using NSDateComponents and NSCalendar:
  
  NSDate*    theDate = <your picker date>
  
  unsigned theUnitFlags = NSYearCalendarUnit | NSMonthCalendarUnit |
  NSDayCalendarUnit;
  NSCalendar* theCalendar = [NSCalendar currentCalendar];
  
  NSDateComponents* theComps = [theCalendar components:theUnitFlags
  fromDate:date];
  [theComps setHour:0];
  [theComps setMinute:0];
  [theComps setSecond:0];
  
  NSDate* theNormalizedDate = [theCalendar dateFromComponents:theComps];
  
  Note that you'll probably also have to play around with the time zone
  (see NSCalendar's setTimeZone:)
