title: iPhone Application button with URL POST method
body: <p>I would like to ask about the button and the url post method in iPhone application.</p>
  
  <p>In my program, I want the user to click a button, and then a url will be called by POST method. For the url, it may need to redirect to somewhere (302 or 303) etc and final is 200.</p>
  
  <p>I have complete the button and the success page, however, I don't know how to use the objective-C library. I found lots of reference of this forum, but I don't understand what the code means. Can anyone help me?</p>
  
  <p>The following is a question which I believe related to the question.
