In my subclassing PDFDocument adventures I wanted to add a method to
my subclass like so:

I realized that it was overriding an internal PDFDocument method
that I was unaware of. This actually helps a big performance
bottleneck in the application because I can use it instead of
creating my own docRef from scratch each time. What I'm not sure
about though is how safe I am using this in my application since it
might break on future OS updates. I'm planning on filing an
enhancement request since it is useful to be able to get a
CGPDFDocumentRef directly from a PDFDocument object. How safe am I
using this method in my application?
Hmmm.... Best of course to check for the symbol and have a fallback
(presuably though a slower fallback method). But I believe you'll
find the symbol you found exists back to Tiger and may be made public
in SnowLeopard. It is something PDF Kit could benefit from — I just
need to make sure the headers don't break (since we'd be declaring a
CoreGraphics type in essentially a Cocoa-universe header).
So, be safe, but stay tuned.
