Calls to those functions are what I have to do to make the decoder work.
If you need to manipulate retain counts directly, the supported mechanisms are:
1. call CFRetain or CFRelease or CFAutorelease.
2. call -retain or -release or -autorelease from a non-ARC file.
Do not call objc_retain or objc_release or objc_autorelease directly.
