iOS: Pulsing red double-height status bar
For reference to what I mean by red status/recording bar, please see the Voice Memos app - it shows up once the recording is started and replaces the status bar with a double thick red bar.
I've been able to get this bar to appear when the app enters the background by flagging the app's background state as being an Audio/VoIP app. The bar does not appear when the user is in the app however - this is what I'd really like to achieve. The Voice Memos app from Apple has this functionality, but I was unable to find any documentation on how to do the same. Does anyone know if this is doable, or would I have to use some sort of library/hack?
