View object having a reference on model object?

89 views Asked by At

I am developing an document based application using MVC pattern, my model object is Mutablearray of mutableDictionaries. Each dictionary in the array is represented to the user by a View object. (for example if the array contain 100 dictionaries then 100 views will be addsubviewed to self.view)

I learned that in MVC pattern the view and model should not know about each other instead they must respond via a Controller object(UIViewController).In my application I followed the MVC pattern but I did not follow the one I mentioned here because by holding a reference to the model object(NSMutableDictionary) I can easily modify the model object(as the user edit the view object) and then write the array of NSMutableDictionaries on the disk after the user finished the document.

Tell me If I should isolate model and view if so what benefit I can avail or I can go on with that
