title: How to get a link to the user's facebook profile on iOS?
body: <p>I have an iOS app which has an in-app comments section. I'd like to ask a user whether they want to "link" their comment name to their facebook page or not. If a user says yes, then I'd like to grab their facebook profile page's web address and store it, so when other users see this user's comment, they can click to go to that person's facebook profile.</p>
  
  <p>Is there any kind of easy way to do this without implementing the full facebook sdk without going through all the authentications?</p>
  
  <p>I'm not very familiar with the Facebook SDK, so any help is appreciated...</p>
