title: Invite Facebook friends to use app from Objective C or PHP
body: <p>I know this question has been asked before, but most of the questions are years old, so maybe Facebook has made available some new api calls.</p>
  
  <p>My question is if its possible (with permissions from Facebook) for one user to invite friends to use a Facebook app through code. Alternatively (second best option) pre fill the required Facebook modal view with friends a user want to invite.</p>
  
  <p>The reason we want to invite friends through code is because we are creating an event app where users can invite friends via contacts from their device or Facebook, and we want to present the user with one contact list where all friends are located (both local contacts and Facebook contacts). When the user has filled out who he/she wants to invite we want to seamlessly invite people both on email and Facebook without the user getting bothered with details (extra views) about how its done.</p>
  
  <p>When user answers yes to the app invitation they are directed to a page where they can answer yes/no to the event.</p>
