How to set the title when playing music with remove control on iPhone?

Question

I'm working on a radio app, which supports playing music in background. But i get stuck in how to set the title of music to remove control.

The difference between my app and "Music" is as following:

What i should do to make my app display the title of a music like "Music" do?

Thanks!

Double tap home button, and right swipe the multitask bar will show this. This view wasn't created by me, it was created by iOS. I'm sorry for my poor English. — OpenThread, May 07 '12 at 07:36

Here's the example code:

#import <MediaPlayer/MPNowPlayingInfoCenter.h>
#import <MediaPlayer/MPMediaItem.h>

MPMediaItemArtwork *albumArt;


- (void)changeTrackTitles
{
  Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter");

    if (playingInfoCenter) 
    {
        albumArt = [[MPMediaItemArtwork alloc] initWithImage: [UIImage imageNamed:@"HexagonArtwork"]];
        NSMutableDictionary *songInfo = [[NSMutableDictionary alloc] init];
        [songInfo setObject:@"SongName" forKey:MPMediaItemPropertyTitle];
        [songInfo setObject:@"AlbumName" forKey:MPMediaItemPropertyAlbumTitle];
        [songInfo setObject:@"ArtistName" forKey:MPMediaItemPropertyArtist];
        [songInfo setObject:albumArt forKey:MPMediaItemPropertyArtwork];
        [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:songInfo];
    }
}

This works well on iOS5, but doesn't support iOS4. How could this be done on iOS4? Thanks a ton! — OpenThread, May 08 '12 at 07:09

You can change the text of the now playing label by calling the MPNowPlayingInfoCenter, this will also allow you to modify the song name, album, artist, and album artwork on the lock screen.

#import <MediaPlayer/MPNowPlayingInfoCenter.h>
#import <MediaPlayer/MPMediaItem.h>

MPMediaItemArtwork *albumArt;


- (void)changeTrackTitles
{
  Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter");

    if (playingInfoCenter) 
    {
        albumArt = [[MPMediaItemArtwork alloc] initWithImage: [UIImage imageNamed:@"HexagonArtwork"]];
        NSMutableDictionary *songInfo = [[NSMutableDictionary alloc] init];
        [songInfo setObject:@"SongName" forKey:MPMediaItemPropertyTitle];
        [songInfo setObject:@"AlbumName" forKey:MPMediaItemPropertyAlbumTitle];
        [songInfo setObject:@"ArtistName" forKey:MPMediaItemPropertyArtist];
        [songInfo setObject:albumArt forKey:MPMediaItemPropertyArtwork];
        [[MPNowPlayingInfoCenter defaultCenter] setNowPlayingInfo:songInfo];
    }
}
