In MVC where do you put references to your model Classes?

Question

I have been wondering for a while, after asking different people and without any of them providing what I would call an \"at least a bit concrete answer\":

It is tempting to put everything in the AppDelegate, but if you start doing this, then your AppDelegate will be full of reference hacks. If you are doing a strict MVC, then you should have 3 things:

• A Model
• A View Controller (Only for view logic)
• A Controller (For coordinating between the view and the model)

So for example, I have a model Foo and a Foo controller. I would have:

• Foo.m (Model)
• FooViewController.m (Displays a Foo)
• FooController.m (Controls the logic)

And finally, to answer your question, I would store my references to Foo's in the foo Controller. I like to use singletons for my controllers, but thats just me. If you do use a singleton, you can just do something like this: [[FooController sharedInstance] listOfFoos] to get your Foo's
