title: iOS acces temporary private files when iPhone is connected to a computer
body: <p>I have an iOS app that is downloading a password protected PDF file. I use some code to unlock the PDF using a password, but I must save it to disk temporarily in order to present in in a view on the screen (I cannot present it only from having it in memory).</p>
  
  <p>My question: Is that temporary file visible when connecting the device to a computer? Is there any private app namespace that makes app files invisible to the computer?</p>
  
  <p>I noticed if I connect the iPhone to a Windows machine, I don't see any files except images.</p>
