What do the terms "identifier" and "accessor" mean?

I have a few things in Obj-C that I need explained. I need a definition and an example. They are: "identifier" and "accessor". Also, how do开发者_StackOverflow社区 I put an "identifier" before a =?

As usual, Google and the official Apple Docs are your friends:

Accessors: Official doc | Other explanation

Id: Id

What do you mean by putting an identifier before '='?

You can only assign what is to the right of '=' to whatever is on the left...

Operators

Most of your questions are not Objective-C specific anyway, seems you need to brush up on general programming concepts.
