Sending messages (calling methods) is fundamental to programming. You already know the basics of Objective-C messages. This chapter delves into the mechanics of how messages are sent, describes three different techniques for invoking methods programmatically, and explains how to write methods that accept a variable number of arguments. It isn’t absolutely necessary to understand these topics in detail, but expanding your knowledge makes technologies like notifications, actions, remote invocation, and Key-Value Observing a little more comprehensible.
