title: Upload File to FTP Server on iPhone
body: <p>I would like to implement logic that uploads file to FTP Server.</p>
  
  <p>I am new in iPhone development, so want to figure out preferred approach. After browsing available API for this task I have managed to find only code that uses CFNetwork (that looks like not Objective C based).</p>
  
  <p>There is also URL Loading System that uses NSURL etc which are Objective C based.</p>
  
  <p>So, my question: Is it possible to use URL Loading System to implement file upload to FTP Server?</p>
  
  <p>Thanks.</p>
