Record voice in background(when i tapped home button) using AVAudioRecorder

Question

I'm new in IOS development.I'm trying to record user voice in background using AVAudioRecorder but I add "audio" to UIBackgroundModes but this don't help. By the way, Everything works perfect in foreground.When in the background the timer works fine but voice is not recording. How can i record from microphone from background ? Is this possible?

Answer 1

You can. Skype does this.

You presumably need to set <key>UIBackgroundModes</key><array><string>audio</string></array> in Info.plist, and you need to make sure that the audio session is active/running/whatever before you switch apps (the assumption is that you won't suddenly start recording/playing music/whatever when your app is in the background).

The docs say that "audio" lets you play audio in the background, but presumably this also applies to recording audio. If it doesn't work, there are a few things you could try:

• Set both "voip" and "audio".
• Play silence (this might be easiest to do with the Audio Queue API).
