I am trying to post data to a PHP web service. I am familiar doing this in html using query $.post but I am very much stumped trying this in objective C.

Both successfully make the web service call(a new userID is created), however they do not post the data, i.e. a blank user is created every time. Please tell me if I am missing anything. Thanks.
