title: Getting facebook wall posts without user login on iOS
body: <p>Edit: I found the solution here:

  <p>Hi,</p>
  
  <p>I read in this thread:
  <a href="https://stackoverflow.com/questions/1000773/facebook-api-without-client-authentication-for-public-content">Facebook API without client authentication for public content</a>
  that it is possible to make facebook api graph requests without the need to log in as a user.
  I tried getting the app access token with a NSURLConnection request,
  but from there I don't know what to do.</p>
  
  <p>How do I get the NSData response into the right format for the token (which is what, a NSString?)?</p>
  
  <p>And how do I send a facebook graph request with the aquired token?</p>
  
  <p>Or is there a simpler way to receive public posts from a facebook wall without the need to login as a user?</p>
  
  <p>Greetings
  Michael</p>
