Tonight I decided to put together a printable document built from the iPhone Dev Center’s reference for UIKit. This document includes three sections (class name + overview section + tasks section) for UIView, plus all subclasses of UIView that appear in the hierarchy tree diagram in the UIKit framework reference.
That’s a mouthful.
Simply put: this document is a condensed, reader’s-digest version of the class references for every visible piece of an iPhone app (not counting custom crazy OpenGL apps and custom drawn stuff. heh)
There are a lot of things available even before getting into the custom drawn things, so to read it all in a nutshell, I copy-pasted all the text and edited it to fit to pages and be nicely readable. The document is a PDF.
