title: How can I get http request body data in codeigniter?
body: <p>I am having trouble getting JSON encoded data POSTed to my CI controller from my IOS obj-c client. I believe that my problem is the same as the one mentioned <a href="https://stackoverflow.com/questions/8569150/codeigniter-rest-server-dealing-with-json-post-request">here</a>. But I cannot find any documentation on a 'request' object on the CodeIgniter site. How can I view/parse the data in an http request body?</p>
  
  <p>$this->request->body  ??</p>
  
  <p>Thanks!</p>
