Subject:  Objective-C Messaging

John Shockey

Sending a message to an object (or, in alternative terminology, calling a method) is at the heart
of what Objective-C does.

I'll start with a brief review of the basics, and then talk a bit about how it works behind the scenes.
I'll also discuss the C language underpinnings of Objective-C messaging. We'll go over a number of
alternate ways of sending messages using various methods and classes from within the Foundation framework,
as well as an optimization that can be occasionally useful to bypass a lot of the normal overhead.

Finally, I'll point out a number of places where it is possible to intervene in the message sending process,
and discuss some cases where you might want to do that.

If there's time, I'll go back and add more detail to areas mentioned earlier.

The talk should range from basic material to a more advanced-intermediate level.
Most of what is covered applies to both Mac OS X and iOS.
