Correct MVC code placement

Subject: Correct MVC code placement

I have many occasions when a model's property needs to be transformed to another type for use in a view. In this case I have a string of pipe separated values that need to be transformed into a NSMutableArray, manipulated in the interface and then converted back to the pipe separated string before saving the model. Should this be in the model or in the controller or are there no hard set rules?

FWIW: NSValueTransformer, for some reason, does not perform/call the reverse transformation back to a string when an array controller is bound to my model's property... it will display the transformed value but like others I found it does not reverse the array back to a string.


Thanks
