title: Background audio playback in UIWebView
body: <p>My app allows users to access a service that plays audio books via the web. I am using a UIWebView to handle this.</p>
  
  <p>When the app is exited or the device is put to sleep, the audio stops playing. Since I am just displaying the web view not playing the audio file directly, I cannot use those methods to play the audio in the background.</p>
  
  <p>However, if you access the same link via the Safari app, the audio keeps playing after the phone is put to sleep. How can I achieve the same effect in my app?</p>
