Rails is not my bread and butter however in iOS I find it'a almost always better to split things out into helper classes. Otherwise when you find that you end up needing that method in other parts of the app and then you either have to break it out into a class anyway or have two of the same method in two separate controllers I.E. NOT what you want. I think the OPs code looks clean and follows OOP.
