title: OAuth Authentication Iphone
body: <p>I am doing an iPhone app which requires OAuth 2.0 protocol to be implemented for the login of the user to a particular website.   I have the client id and client secret which i got after registering my application on the website.  I would like to know a few things about this.</p>
  
  <ol>
  <li><p>I saw a number of links regarding this. But yet in my head I'm not very sure of whether i need to use OAuth classes or OAuth consumer classes?</p></li>
  <li><p>Is authentication of the user possible in OAuth without sending the email id and password of the user in a query string? </p></li>
  <li><p>Is is possible to load the website in a uiwebview and login to the website and get the user credentials for the further screen functionalities.</p></li>
  </ol>
  
  <p>This is the first kind of such an app I'm developing. It would be great if someone could help me out so that i can know clearly how i should go about.</p>
  
  <p><strong>EDIT:</strong> if there any good tutorials for achieving Login to a website using OAuth please do share. </p>
  
  <p>Thanks in advance</p>
