title: Upload things to a FTP in Objective-C iOS
body: <p>Some days ago I was asking how to download files from a FTP and I solver my problem with NSData and dataWithContentsOfURL of this kind:</p>
  
  <p><code>ftp://user:pass@server/path/of/file.extension</code></p>
  
  <p>But now I need to upload a file, and I was wondering if there is any instruction to upload files through an URL but I think it could not be possible and many many libraries I saw for iOS use PHP and I don't want it, and SimpleFTPSample from Apple is so confusing for junior developers that I could not understand nothing, so a simple code to upload a file specifying URL, Path, File, user and pass?</p>
