The subject pretty much says it all. I need to access the Cancel button of a
search bar, so I can change its title. I couldn't find a way to set an outlet

ideas?
Thanks in advance.

Is the fact that -initWithFrame: is the designated initializer documented
anywhere? The docs for UIButton don't mention it. If this is documented and
elf. Once the swiping and
reordering (as in the Autoscroll sample code) have been dealt with, this
"proxy" UIView instance can decide if/when to forward a tap gesture to the
button. So, yes, composition seems to be the way to go here.

s, but I'd prefer to have actual UIButton instances.
Am I missing something trivial here? If UIButton was designed in such a way to
prevent subclassing, what would you suggest as the best alternative?
