title: Has Apple officially not allowed access to camera for app in background?
body: <p>Can I build an iOS app that uses the camera (even if it doesn't take pictures/video) while the app is in the background? </p>
  
  <p>If not, why? Where has Apple come out with this information? <strong>I have seen similar questions and answers, but none with direct proof from Apple.</strong></p>
  
  <p>For example, if I wanted to make an app that, while in background, can keep track of how many trees our phone encounters through the day through object recognition software.</p>
