After seeing how the Cocoa-bundled About box works, we’ll create a new About box from scratch for our Calculator. We will use this new About box to demonstrate how to manage multiple nibs (interfaces) within a single application. In the last section of this chapter, we’ll see how Cocoa allows you to specify an icon for an application.
