    What does it all mean?

    I am just starting out trying to design iOS apps on XCode 4.2

    I have used C before, but only at a basic(ish) level; basically I can look at some code and tell you what is going on with about 90% of it - but when it comes to writing it I am terrible.

    But I haven't used Objective-C before, so even writing my "Hello World!" program is proving to be a little difficult.

    Can anybody help me with what the following does within the code:

    - (IBaction)
    - (id)
    - sender
    - @ (<< used before "Hello World!")

    This is a great outline and explains all the code snippets you've asked about:

    It assumes a base-level knowledge of some kind of C or C++ language, which, in my opinion, is paramount to understanding Objective-C.
