NSDocument is an AppKit class used to implement document-based applications. It is subclassed so that instances represent specific "document" types.

Code chunks

Multiple editors

If your document uses multiple editors and each is represented with a single NSWindowController, you can commit all edits like in the following (obvious) code. Requirement is, that each NSWindowController should implement commitEditing.

- (void)commitEdits
{
   NSWindowController *controller;
   NSEnumerator       *enumerator;
   
   enumerator = [[self windowControllers] objectEnumerator];
   
   while( (controller = [enumerator nextObject]) )
   {
       if([controller respondsToSelector:@selector(commitEditing)])
       {
           [controller commitEditing];
       }
   }
}
