Yeah, UIToolbars are odd beasts. Try this out: place a UISwitch in a toolbar,
hook it up to an IBAction, and you get... nothing. It switches from ON to OFF
and back, but the action never fires. Bug? Feature? Not exactly 'standard and
easy' imho. Maybe the 'next major release' will address this.

I agree: that's how I expected it to work, too, but that's not how it does work
(Xcode 3.2.4). If I drag a Round Rect Button onto the Toolbar, it instantly gets
promoted to a UIBarButtonItem (really!), and I can't set "Touch Down" on it, nor
can I change the class of it in IB. That's why I'm confused...
