Add this to your program, in the object in which you wish to perform
the save/don't save dialog:

   [[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(windowWillClose:) name:NSWindowWillCloseNotification
object:window];


- (void) windowWillClose:(NSNotification *)notification
{
   NSWindow *windowAboutToClose = [notification object];

   if (windowAboutToClose == myWindow)
       [NSApp beginSheet:mySavePanel modalForWindow:myWindow
modalDelegate:self didEndSelector:@selector(sheetDidEnd:)
contextInfo:nil];

}

- (void)sheetDidEnd:(NSWindow *)sheet returnCode:(int)returnCode
contextInfo:(void  *)contextInfo
{
   [[NSNotificationCenter defaultCenter] removeObserver:self
name:NSWindowWillCloseNotification object:window];

   // handle the returnCode
}
