I'm reading the book Cocoa Programming, by Anguish,Buck and Yacktman. It was

AppKit framework. However C is not mature as it could be. Here's a small
quote.


If you are creating a document-centric application, then the various classes
surrounding the NSDocument class will provide much of the controller logic
you need. Sadly, in other parts of the controller layer, Cocoa does not yet
provide much help. … There is no generic "controller framework.... The lack
of a controller framework is one area that could stand improvement. Note
that Apple does have some generic controller objects that would help.


My question is if there has been any improving in this area the last 5 years
since the book was written.

That's a rather odd statement for the book to be making. The Foundation storage classes (NS[Mutable]Array, et. al.) are only a small part of the framework, and certainly aren't a viable substitute for a model class in anything but the simplest applications. Similarly, AppKit views don't suit the needs of all applications either - they're certainly useful, but most applications will need at least one subclassed or custom view somewhere.


Claiming that controllers can be prepackaged in a similar fashion is just silly. In most applications, the controllers are where much of your application's unique logic will live. These can't be written for you! _______________________________________________
