Question

I am making an app that plays audio… with each sound piece playing I want to be able to change the “album cover” on the wallpaper of the phone… For example when you play a song on the iPod app it changes your lock screen wallpaper to an album cover photo… so how do I do this for my app, when audio is playing within my app changing the lock screen wallpaper temporarily to the album cover? Any ideas? I was thinking of playing an audio file that actually has a picture compressed into it as the wallpaper image like some iTunes songs but I know not all do that and they still get images.. hmmm Anyways I know it’s possible because I own some apps that do that… Thanks if anyone can come up with anything!

In iOS5+ you can use the MPNowPlayingInfoCenter Class to achieve what you want. On version prior iOS5 this is not possible with public APIs.
