Description Timothy Risi 2013-08-20 19:26:38 UTC
The ValueForKey and and SetValueForKey methods on NSDictionary (And NSMutableDictionary as well) only accept an NSString for the key parameter.  An NSDictionary can have any NSObject as a key, not just an NSString, so you are unable to access anything using a non-NSString key.

There's an indexer that accept an NSObject instance (beside the one for string and NSString) so:

    dict [new NSObject ()] = new NSObject ();

is possible today and much more nicer looking, source wise, that using `ValueForKey`. 

FWIW `ValueForKey` comes from `NSObject` not `NSDictionary`.
