The Smalltalk teams at Xerox PARC eventually settled on a design in defense of food pdf philosophy that led to easy development and high code reuse. For end-users, Cocoa applications are those written using the Cocoa programming environment. This restricts the design of an application since specific command handling classes are needed, usually organized according to the chain-of-responsibility pattern.

Compared to similar MVC systems, OpenStep lacked a strong model layer. Objects that derive from the NSObject root class respond to a in defense of food pdf retain and a release message, and keep a retain count. During the transition to Cocoa, the model layer was expanded greatly, introducing a number of pre-rolled classes to provide functionality common to desktop applications. One of the most useful features of Cocoa is the powerful base objects the system supplies. Spell checking is automatic, using a single dictionary used by all applications that uses the squiggly underlining convention introduced by Microsoft (actually a dashed red underline in Cocoa). One feature of the Cocoa environment is in defense of food pdf its facility for managing dynamically allocated memory. Under OpenStep, most of the classes provided were either high-level View classes (in AppKit) or one of a number of relatively low-level model classes like NSString. It contains code programs can use to create and interact with graphical user interfaces. Model classes in defense of food pdf represent raw data, such as documents, settings, files, or objects in memory.

Controller classes contain logic that links the models to their views, and maintains state to keep them synchronized.
