Objective C - POST data using NSURLConnection

Question

I\'m very slowly working my way through learning the URL loading system for iOS development, and I am hoping someone could briefly explain the following piece of code:

Answer 1

This is a pretty simple HTTP request setup; if you have more specific questions you might do better asking those.

NSString *myParameters = @"paramOne=valueOne¶mTwo=valueTwo";

This sets up a string containing the POST parameters.

[myRequest setHTTPMethod:@"POST"];

The request needs to be a POST request.

[myRequest setHTTPBody:[myParameters dataUsingEncoding:NSUTF8StringEncoding]];

This puts the parameters into the post body (they need to be raw data, so we first encode them as UTF-8).
