Using private APIs

From time to time someone posts a question about using non-public Apple APIs -- you know, the ones that let you do something really cool or fast but causes your app to break on a future OS release. :) Anyways, I saw this purported private API for OS X, and I thought I'd share it. Pretty fu

Graham, I'm not sure if this is exactly what you were talking about, but I did a test in the printShowingPrintPanel of a program I'd written. The NSPrintInfo methods setLeftMargin, setBottomMargin, setRightMargin and setTopMargin all affect the margin values within the NSPrintInfo instance. H

-init and -dealloc are special in that the object is not in a consistent state during those methods (it either hasn't yet entered it's "initial" state or is transitioning out of its "final" state). If your accessors rely on the internal state of the object being "normal", they could blow up
