title: UIPickerView data fron NSDictionary
body: <p>I have date from web service like this:</p>
  
  <pre><code>{
              "idlife_stage_question" = 43;//..basically this should be key
              "life_stage_idlife_stage" = 1;
              "profile_idprofile" = 0;
              "question_text" = "example";//..this should be object
              sequence = 42;
      }
  </code></pre>
  
  <p>Now i need "idlife_stage_question" and "question_text" from each dictionary of JSON and load "question_text" in a UIPickerView and then show the selected row text in a UILabel. Further i need to fetch "idlife_stage_question" for corresponding  "question_text" so that i can send "idlife_stage_question" to server later on. How can i do this with an NSDictionary?</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>My req is:</p>
  
  <ol>
  <li>Get "idlife_stage_question" and "question_text" from JSON.</li>
  <li>Set "idlife_stage_question" and "question_text" in NSMutableDictionary</li>
  <li>Populate UIPicker with "question_text"</li>
  <li>Show selected row text in a label</li>
  <li>Get "idlife_stage_question" fron NSMutableDictionary corresponding to the "question_text" to send it to server.</li>
  </ol>
