Back button appearance for UIBarButtonItem in toolbar?

[Paul Cantrell]

A UIBarButtonItem takes on a left-pointing arrow "back button" appearance when used as the back button in a navigation bar.

Does anybody know if there's a way to make it take on that appearance when it's part of a UIToolbar? I don't think there's a way other than creating custom art, but I thought I'd check.

Cheers,

Paul

I looked into this a while back too - and resorted to creating my own artwork. I couldn't find a way to do it.

There was a discussion about this on Stack Overflow about how it's against the Human Interface Guidelines and why you shouldn't do it, etc.  That said, you might want to check out the http://github.com/facebook/three20 project - pretty sure there's included support for back buttons.  Probably heavyweight for what you want but might provide a good starting point.

I've got an iPad app with a top bar similar to the one in the YouTube app which is sort of a nav / tool hybrid. For various reasons it's easier to implement it as a UIToolbar and not a UINavigationBar, but I do want back button art for back button behavior.

three20 is indeed overkill, but maybe I'll check out their code and see how they do it.

Thanks for the confirmation that this isn't supported.

Cheers, P
