How to continue audio playback in background mode

Question

I have a UIWebView that plays video clips in my view controller. When I exit the app, the audio will stop playing, although I can press play in the control center to continue it

Answer 1

Try to update you code with this:

var error: NSError?
var success = AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback, error: &error)
if success {
    AVAudioSession.sharedInstance().setActive(true, error: nil)
    UIApplication.sharedApplication().beginReceivingRemoteControlEvents() 
} else {
    NSLog("Failed to set audio session category.  Error: \(error)")
}

Important:

1. Don't use simulator for tests. Background playback doesn't work in the Simulator;
2. Call above code before creating UIWebView instance.
