Question

There is a way to add an image to the lock screen for Background Audio, along with setting the Track and Artist name. It was also mentioned in a WWDC 2011 video, but nothing specific to go off of. I have looked everywhere in the docs and cannot find it. I know it is an iOS5 only thing, and Spotify’s newest version has this feature. Does anyone know where they can point me in the right direction?

Thank You,
Matthew

Here’s an answer I found for you:

(1) You must handle remote control events. You can’t be the Now
Playing app unless you do. (See the AudioMixer (MixerHost) sample) code.)

(2) Set the Now Playing info:

MPNowPlayingInfoCenter *infoCenter = [MPNowPlayingInfoCenter defaultCenter]; 
infoCenter.nowPlayingInfo = 
    [NSDictionary dictionaryWithObjectsAndKeys:@"my title", MPMediaItemPropertyTitle,
                                               @"my artist", MPMediaItemPropertyArtist,
                                               nil];

This is independent of whichever API you are using to play audio or
video.
