title: how to convert php return NSData into NSDictionary
body: <p>HI,
  i am creating an login screen to my iphone application. i am sending the username and password to php using NSURLConnection method. i can successfully send login details to php. My php page returning status values based on the login details.</p>
  
  <p><strong>(status =OK / Fail , redirectionUrl=<a href="http://www.balalaa.com" rel="nofollow noreferrer">http://www.balalaa.com</a>)</strong></p>
  
  <p>In DidReceiveData method if i convert the NSData into string i am getting following string for successful login </p>
  
  <p><strong>"STATUS=OK&amp;url=<a href="http://www.balalaa.com" rel="nofollow noreferrer">http://www.balalaa.com</a>".</strong> </p>
  
  <p>Is there any way to fetch the values of STATUS and url, without using NSPredict. Is there any other way to conert the NSData into NSDictionary to fetch values for STATUS key? </p>
  
  <p>Thanks in advance.
