As with the interface, you start by importing:
#import "BMPerson.h"
If you recall, you imported the Cocoa framework differently:
#import
Why the change in syntax? When importing system frameworks, use the path notation and
the angle brackets. When importing your own headers, use the quote notation.
Incidentally, you don’t have to import Cocoa into this implementation, because the header
has already imported it. Importing a header also imports any headers it has imported. As you can
imagine, that gets complicated quickly, which is why we use #import and not #include.
You open the implementation with the @implementation directive and the name of the class:
@implementation BMPerson
You don’t have to rename the superclass or redeclare the instance variables, so you can
move right into methods.
Class Methods
The methods are opened with the same declaration as in the header:
