I would add that any graph of objects that implements the <NSCoding> protocol can also be trivially copied. Interface Builder encodes and decodes object graphs when saving the xib/nib files and also when entering test interface mode.
As a blatant plug: See "Cocoa Design Patterns" ISBN: 0-321-53502-2 Chapters 11, "Archiving & Unarchiving", and 12 "Copying". --- On Fri, 9/3/10, Matt Neuburg <m...@tidbits.com> wrote: > From: Matt Neuburg <m...@tidbits.com> > Subject: Re: UIView animation > To: "Christian Ziegler" <chris.zieg...@me.com> > Cc: cocoa-dev@lists.apple.com > Date: Friday, September 3, 2010, 11:50 AM > On Fri, 03 Sep 2010 00:11:43 +0200, > Christian Ziegler <chris.zieg...@me.com> > said: > >Hi all, > > > >I could use your help because I'm running out of > ideas! > > > >Here's the situation.
