     3The visual elements of your application's user interface are all ready now. The last thing you must do is create descruptions of any custom classes used by the application when users interact with the interface.

     5When a user clicks the "Convert" button, it should send a message to an instance of a custom class that causes the conversion to take place, and the result to be displayed in the "Amount" field. In order for the application to connect the user interface to objects that perform these actions, you must add descriptions of your classes and instances to the nibfile. Fortunately, !InterfaceBuilder can create class and instance descriptions and save them in the nibfile for you.
