Re: how to make cocoa application run as a command line tool?

The clean solution for this is to refactor your application into a framework, a Cocoa application and a command line tool. The framework contains all the document logic (the model part of the MVC pattern). Both the Cocoa application and the command line tool use the framework. The tricky

I would tend to use a simpler pattern: make assign outlets on file's owner for each top-level object, and release them in -dealloc. This pattern is based on the tendency for nibs to be "part of" another object. For example, think of NSWindowController or NSViewController. Logically, the object g
