Question

Its my first time to use web service in iOS.
REST was my first choice and I use code igniter to form it.

I have my Controller:

require APPPATH.'/libraries/REST_Controller.php';

class Sample extends REST_Controller
{

    function example_get()
    {
        $this->load->helper('arh');
        $this->load->model('users');

        $users_array = array();
        $users = $this->users->get_all_users();

        foreach($users as $user){
            $new_array = array( 
                                'id'=>$user->id , 
                                'name'=>$user->name,
                                'age'=>$user->age,
                              );
            array_push( $users_array, $new_array);
        }

        $data['users'] = $users_array;      
        if($data)
        {
            $this->response($data, 200);
        }
    }

    function user_put()
    {  
        $this->load->model('users');
        $this->users->insertAUser();

        $message = array('message' => 'ADDED!');
        $this->response($message, 200);

    } 

}

, using my web browser, accessing the URL http://localhost:8888/restApi/index.php/sample/example/format/json really works fine and gives this output:

{"users":[{"id":"1","name":"Porcopio","age":"99"},{"id":"2","name":"Name1","age":"24"},{"id":"3","name":"Porcopio","age":"99"},{"id":"4","name":"Porcopio","age":"99"},{"id":"5","name":"Luna","age":"99"}]}

, this gives me a great output using RKRequest by RestKit in my app.

The problem goes with the put method. This URL :

http://localhost:8888/restApi/index.php/sample/user

always give me an error like this:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

<xml>
<status/>
<error>Unknown method.</error>

This is my Users model

<?php

    class Users extends CI_Model {
        function __construct()
        {
            parent::__construct();
        }

        function get_all_users()
        {
            $this->load->database();
            $query = $this->db->get('users');
            return $query->result();
        }

        function insertAUser(){
            $this->load->database();
            $data = array('name'=> "Sample Name", 'age'=>"99");
            $this->db->insert('users', $data);
        }
    }
?>

What is the work around for my _put method why am I not inserting anything?
Thanks all!

I got this problem by using Firefox plug in rest Client.
I just have to indicate the headers and the body to make put and post work.
