[Pyobjc-dev] Docs unhelpful

[Andrew P. <and...@gm...>]

I know ObjC, and I know Python. What I do not know is:

* How to convert between NSString and Python string.
* How to convert (id) something into an NSString (and then to a Python
string).
* How to create an NSArray of NSStrings using NSArray.arrayWithObjects and
Python strings.
* Whether None is an acceptable substitute for ObjC's nil.

None of these are found in the PyObjC docs. Instead, I just see which things
aren't implemented yet. That's extremely unhelpful.
