I get the warning that valueForKeyPath: is not found in the protocols. If I
change the instance variable to id AudionetQueueDelegate,NSKeyValueCoding, I
get the error that the NSKeyValueCoding protocol can not be found. If I also
AFAIK, when something is referenced as a protocol like that, the *only* methods
it knows about are the ones in the protocol. If you just cast the delegate to
type id, you should be OK (I have encountered similar situations where this
solution worked)

Your AudionetQueueDelegate protocol is probably not inheriting from
NSObject (the protocol) so it warns that valueForKeyPath: is not
found. It'll also probably complain about methods like
respondsToSelector: which is also part of the NSObject protocol.
You need to write your protocol

Yes that wont work, which is why I said NSObject* protocol instead of
idNSObject,protocol
valueForKeyPath: is not defined in the NSObject protocol, but is defined on
NSObject itself which is why it works.

I was surprised to learn that a hierarchy of NSDictionary objects can
be queried with valueForKeyPath:
NSDictionary *dict0 = [NSDictionary dictionaryWithObjectsAndKeys:@got
me!, @2, nil];
NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:dict0,
@1, nil];
NSLog([dict

I've been busy adding some structure to the NSUserDefaults in my app. So I
would have a dictionary like 'generalPrefs' with some key/value pairs,
separate from 'otherPrefs' etc.
Now I wonder why the following doesn't work:
[[NSUserDefaultsController sharedUserDefaultsController] valueForKeyPath
