Yeah, definitely you can build reusable pieces -- you can look at http://github.com/joehewitt/three20/tree/master as an example of a well-known one ... I would suggest that the only way to do it WELL at the UI-level (aside from things like cells, etc) is to also build the corresponding IB palettes, though.

Cocoa is OO, and you can create reusable elements. For example, you can easily create a reusable UITableViewCell that takes an object to create all the necessary display content you want in the cell.

The apps I've written are mostly coded outside of IB. However, I would think you should still be able to blend the two.

FWIW, regardless of how OT it is I would be interested in the answers as well.

I know of one person who has built an application template that he bases new apps on, but am not aware of anyone doing this with the UI. I think the reliance on Interface Builder is partly to blame; unless you code all your UI elements by hand to start with there is nothing to reuse. Not easily, anyway. But I'd be happy to be proven wrong.

Hello,

(I hope this isn't too far OT.  Feel free to flame.  :-))

Obviously a very common pattern in WO is finding common elements in one's UI and breaking those out into a re-usable component--- encapsulation and code re-use. I've recently waded into some Cocoa Touch development, and one of the first things I tried to do with a UI I was create the equivalent of such a "re-usable component". It turned out to be harder than I thought---I won't go into the specifics, because it's even further off-topic for this list. I just had a quick question for any WO people also working with Cocoa Touch: am I trying to do something that would be considered unusual on that platform? I posted on Apple's iPhone developer forums, and got a couple of basically helpful answers, but, to be honest, they didn't smell quite right. For example, someone wrote:

What you're trying to do is something that no one else is doing. There is no 'usual way.' UI's on iPhone are generally much simpler than those on desktop apps so there's very little reason to have plugins or component UIs like you describe.

I find this hard to believe. In any case, sorry for the off- topic post. Feel free to limit answers to "You're crazy" or "Of course you can make re-usable UI components", or even reply off- list.
