What is message in objective-c?

---

Messages in Objective-C are akin to method calls in C++.

In Objective-C, you don't call a method, you send a message.

If you're at that level of understanding/bemusement, then I'd recommend a read of Apple's excellent "Introduction to The Objective-C Programming Language", as you really need to understand some of the basics before you get any further.

In essence, a message is effectively a method call in Objective-C. (Instead of passing arguments to a method, you "send a message".)
