AVAudioPlayer doesn't start playing in background

Question

I am using AVAudioPlayer and NSFileHandle to do audio streaming. The basic idea is that I save the streaming audio data to the device with file sys

Answer 1

Your app cannot start playing audio in the background. And this makes sense. Think what the device would be like if an app that the user is not actively using could suddenly start producing sound! Remember, to the user, sending an app to the background is the naive equivalent of quitting that app. Your app must not rise like a zombie from the dead and start making noise!

The background audio setting allows your app that was producing audio while in the foreground to continue to do so when it then goes into the the background. It then can continue being in charge of the audio (if it receives remote events) until some other app produces sound; after that, your app is once again out of the running until it is brought to the foreground and produces sound.

So you'll need to start playing some sound before your app goes into the background, if you want this to work.
