I’m very slowly working my way through learning the URL loading system for iOS

  • 0

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:

NSString *myParameters = [[NSString alloc] initWithFormat:@"one=two&three=four"];
[myRequest setHTTPMethod:@"POST"];
[myRequest setHTTPBody:[myParameters dataUsingEncoding:NSUTF8StringEncoding]];

Eventually I would like to be able to create an application that logs into my ISP’s website and retrieves how much data I have left for the rest of the month, and I feel as though I should get my head around setHTTPMethod/setHTTPBody first.

Kind regards

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

    NSString *myParameters = @"paramOne=valueOne&paramTwo=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).
