title: Get priority and uptime from pid? ( iOS )
body: <p>This is for an app intended for the app store.</p>
  
  <p>Using the code <a href="https://stackoverflow.com/questions/4312613/can-we-retrieve-the-applications-currently-running-in-iphone-and-ipad">from here</a>, I can get a list of running processes and their pids. However, I've found several apps in the appstore (<a href="http://itunes.apple.com/us/app/battery-memory-system-status/id497937231?mt=8" rel="nofollow noreferrer">like this one</a> that have also retrieved each process's <strong>priority</strong> and <strong>start time.</strong>  </p>
  
  <p>(Note: I don't care whether it's uptime, for how long the process has been active, or the wall clock date/time the process started).</p>
  
  <p>Is there any documented way to do this?</p>
