This is a joke right? You seriously expect someone to fully describe and document the entire Cocoa library for you? That'd take tens, if not hundreds, of thousands of words.

Apple have already done this. There is full, in depth, documentation installed with XCode and available online. There are numerous conceptual articles and guides.

I'd recommend starting at the the start with the basic tutorial and then reading the documentation.

I also think this must be a joke.

As for your second question, when you say you can't pass strings, what do you mean? You can't pass strings, only pointers. Same as C.

All of the documentation is in Xcode, or can be downloaded to Xcode if it is out of date.

Simply go to the Help menu and select Documentation. In the search field you can type NSString and it will show you the class description and methods for that class, or any other class.

I'll just say that this programming forum has suffered a massive decline in quality ever since the iPhone SDK was released.

I feel it would be very beneficial for us to make a sticky/guide that is:
I've never programmed anything before, or have never programmed on the Mac. I want to make an iPhone application, what should I do?

I've personally answered that half a dozen times, and many others have as well. I think we can all agree on general steps and either leave out contentious issues like the best editor or include an objective list instead of any one person expressing subjective preference.

I doubt it would stop the questions, but would allow for the response to be "check the guide" rather than regurgitating the same advice.

Maybe. Also seem to be a lot of questions from people who want us to do their homework or work assignments for them.
