How to set an title of the currently playing audio

2019-01-13 11:56发布

When you play a music, the music title is shown below the time in the lock screen.

I have also seen how TuneIn radio does that by showing the name of the currently playing radio station.

How do you do that?

Read the documentation: MPNowPlayingInfoCenter

And here is an example code that will work on iOS 5 and it will not crash on older versions of iOS.

Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter");

if (playingInfoCenter) {
    MPNowPlayingInfoCenter *center = [MPNowPlayingInfoCenter defaultCenter];
    NSDictionary *songInfo = [NSDictionary dictionaryWithObjectsAndKeys:
                             @"Some artist", MPMediaItemPropertyArtist,
                             @"Some title", MPMediaItemPropertyTitle,
                             @"Some Album", MPMediaItemPropertyAlbumTitle,
                             nil];
    center.nowPlayingInfo = songInfo;
}
