I'm not grasping where there can be any source of confusion here. awakeFromNib is very simple: it is sent to an object after that object is instantiated from a nib. That's straightforward and dependable and clear - provided you know what a nib is, of course. The only "subtle difference" between Mac OS X and iOS in this regard is that in iOS you are enjoined to call super in your implementation. (There are some memory management differences for objects instantiation from nibs between Mac OS X and iOS, but that's a different matter.) What you say about viewDidLoad is perfectly true, but should not be an issue provided you do in viewDidLoad only things that are suitable for viewDidLoad (i.e. things that can do no harm if done more than once). m. -- matt neuburg, phd = m...@tidbits.com, <http://www.apeth.net/matt/> A fool + a tool + an autorelease pool = cool!
