Also, are the _ in front of member variables for Apple only (so
we don't stomp on each other with member var names) or are they
using them for the readability reason mentioned above? There is
documentation where they have claimed _ at the beginning of
method names as being Apple only, but nothing about method vars,
and the KVC compliance docs seem to imply that it is fine to do.
Officially it is Apple only, but everybody and his dog uses it -
in consistency to quite some Apple-provided samples.
Please file bugs when you see a sample that does so. A single
leading underscore is an Apple internal coding convention, which
should not be used for code samples. I did what I could to get
those kinds of things fixed when I was there, but someone's got to
file a bug for it to get noticed.
In this case I should probably first file feature requests
- for an additional naming convention proposal for ivars which for
every other framework / platform I've seen (PowerPlant, MacApp, MFC,
Java et al.) exist. My preference was a _trailing_ underscore which
is also OK for C++ etc.
- automatic support for KVC for that ivar convention so not only
Apple gets away with minimum accessor code to write (Jepp, I know
@synthesize made it far easier)
You have KVC support for the underscore.

Or did you mean support for another symbol?
