My MainViewController is getting big. How can I divide it?

I am using XCode 4.0.2 for a iOS4 (iPhone) project with a great number (40) FieldText and other objects (a slider for example).

I have a MainViewController.h and a MainViewController.m among other things (AppDelegate, FlipsideViewController, custom classes, etc).

Now the MainViewController.m is getting big (1700 rows). How can I divide this in two o three files? Perhaps moving some 开发者_如何学编程delegate methods in a new file? Or something else?

Thank you.

Delegate methods are good candidates to be factored out.

You could also try some general refactoring techniques, e.g., if you identify functionality that seems likely to be reused in other classes that could guide your redesign.

Anyway, without seeing the code is really difficult to come up with more concrete suggestions.
