Undocumented API Rejection

[Jim Heising]

Hey all, I'm wondering if any of you might be able to help me out
here. We just got an app rejection from Apple with the following:

"3.3.1 Applications may only use Documented APIs in the manner
prescribed by Apple and must not use or call any private APIs."

The non-public API that is included in your application is OBJC_IVAR_
$_NSObject.isa.

This is a new one for us, and has me scratching my head. I've done a
search through the code and can't find a reference to this anywhere.
We just recently upgraded our Facebook connect library-- could it be
in there? Any help would be greatly appreciated. Thanks!

Jim,

I think you'll find that some code is assigning the isa member of one
of your classes. This is a quick way to make an object act like a
different object ("swizzling," I believe they call it).

I had a rejection due to similar code in a different library. Try
searching all of the code (including all open source & fbconnect) for
'isa'.

An iphone dev chat group said the same thing about the isa member. You mentioned facebook. You're not using Joe Hewitt's three20 library are you? I heard that had some problems...

Found it. KissXML is the culprit.

self->isa = [DDXMLElement class];

Thanks for the help!

KissXML got me too (I couldn't remember which when I iPhoned that answer in). Robbie fixed it, so you should be a source pull away. There's some debate as to whether this is actually an "undocumented API" at all...

Yeah I got the latest source and I think we're good now (hopefully).
