Does NSFoundation have a data structure like the std::map? NSMutableDictionary is close, but doesn't seem to have any way to check if a certain key is already inside.

That's excellent, but how come the documentation makes no mention of this function?
http://developer.apple.com/library/...ableDictionary_Class/Reference/Reference.html

Is there any documentation that lists ALL the functions?

Thanks.

Because Apple do not duplicate the documentation from superclasses in subclasses. The objectForKey: method (not function) is defined in NSDictionary which is NSMutableDictionaries superclass. So any NSDictionary method can be called on a NSMutableDictionary.
