Is there a way to construct an object automatically from an NSDictionary?

I'm building an iPhone app that communicates with an external server via JSON. The JSON library I'm using parses the response string from the server into a dictionary. Currently I've got a method that I've written that just uses hardcoded strin开发者_如何学编程gs as keys for the dictionary in a constructor I've written called initWithDictionary:(NSDictionary *)dic (e.g. self.name = [dic valueForKey:@"name"];. Is there some smart idiomatic Objective-C way to do this?

Just call [someObject setValuesForKeysWithDictionary:dictFromJSON] to set an object's properties from a dictionary.
