Showing a lock screen image using MPNowPlayingInfoCenter doesn't work

Question

I have the following code and is working for me but it can only currently show artist and song :

let mpic = MPNowPlayingInfoCenter.defaultCenter()

mpic.nowPlayingInfo = [MPMediaItemPropertyTitle:songs[currentAudioIndex].songName,
                        MPMediaItemPropertyArtist:songs[currentAudioIndex].artistName]

I tried also setting the picture with the following code but it isn't working :

mpic.nowPlayingInfo = [MPMediaItemPropertyTitle:songs[currentAudioIndex].songName,
                    MPMediaItemPropertyArtist:songs[currentAudioIndex].artistName,
                    MPMediaItemPropertyArtwork:songs[currentAudioIndex].songImage]

SongImage is of type UIImage.

Answer 1

Never mind I figured out.

If anyone want to learn you have to do the following

    let mpic = MPNowPlayingInfoCenter.defaultCenter()

// initialize an instance of MPMediaItemArtWork with a UIImage

    var albumArtWork = MPMediaItemArtwork(image: songs[currentAudioIndex].songImage)

// Then assign it to the MPNowPlayingInfoCenter

    mpic.nowPlayingInfo = [
        MPMediaItemPropertyTitle:songs[currentAudioIndex].songName,
        MPMediaItemPropertyArtist:songs[currentAudioIndex].artistName,
        MPMediaItemPropertyArtwork:albumArtWork

    ]

Hope this helps anyone who is also struggling with this.

Thanks
