[bug #24807] NSUserDefaults doesn't support KVC

[Richard Frith-Macdonald]

Update of bug #24807 (project gnustep):

                  Status:                    None => Fixed                  
             Open/Closed:                    Open => Closed

Follow-up Comment #1:

I implemented the trivial valueForKey: and setValue:forKey: methods ...though
it's not entirely clear that NSUserDefaults should be KVC complient.

I couldn't find any documentation saying that the class is KVC complient in
MacOS-X, and I did find a couple of comments on the web from people saying
they thought it wasn't.
I also found this page ...
http://developer.apple.com/documentation/Cocoa/Conceptual/CocoaBindings/Concepts/NSUserDefaultsController.html

At the end it says:
The NSUserDefaultsController method values returns a KVC-compliant object
that is used to access these default values. To get the value of a default,
use the valueForKey: method.

[[theDefaultsController values] valueForKey:@"userName"];

which seems to imply that NSUserDefaults is not KVC compliant (as it needs
this special KVC-compliant object to access it).

However, your test program returns a value when I run it on MacOS-X, so it
seems likely that Apple have added KVC as an undocumented feature, or are in
the process of adding it.
