IOS::How to get the MPMediaquery Songsquery Artwork - ios7

Question

I'm using this code for getting the Artwork, but it's not workout for me. What's the wrong in this code.Suggest me.
Thanks.
MPMediaQuery *mySongsQuery = [MPMediaQuery songsQuery];
NSArray *SongsList = [mySongsQuery collections];
for (MPMediaItemCollection *SongsArt in SongsList) {
NSArray *songs = [SongsArt items];
for (MPMediaItem *song in songs) {
if ([(MPMediaItem*)item valueForProperty:MPMediaItemPropertyAssetURL] != nil) {
CGSize artworkImageViewSize = CGSizeMake(40, 40);
MPMediaItemArtwork *artwork = [song valueForProperty:MPMediaItemPropertyArtwork];
UIImage * image = [artwork imageWithSize:artworkImageViewSize];
if (image!= nil)
{
imgv_songImageView.image = image;
}
else
{
imgv_songImageView.image = [UIImage imageNamed:#"musicD-jpeg.png"];
}
}
}

Answer 1

I assume you just want to loop through all songs in the music library so I don't see a need for collections:
MPMediaQuery *mySongsQuery = [MPMediaQuery songsQuery];
for (MPMediaItem *item in mySongsQuery.items) {
if (![[item valueForProperty:MPMediaItemPropertyIsCloudItem]boolValue]) {
CGSize artworkImageViewSize = CGSizeMake(40, 40);
MPMediaItemArtwork *artwork = [song valueForProperty:MPMediaItemPropertyArtwork];
UIImage *image = [artwork imageWithSize:artworkImageViewSize];
if (image) {
imgv_songImageView.image = image;
} else {
imgv_songImageView.image = [UIImage imageNamed:#"musicD-jpeg.png"];
}
}
}
I'm not sure why you want to check for the Asset URL but I've left it in.

Here i am posting the code to get the tracks and sorting them alphabetically. Its written in swift3.
/// Get all the songs in the device and display in the tableview
///
func getAllSongs() {
let query: MPMediaQuery = MPMediaQuery.songs()
let allSongs = query.items
allSongItems?.removeAll()
guard allSongs != nil else {
return
}
var index = 0
for item in allSongs! {
let pathURL: URL? = item.value(forProperty: MPMediaItemPropertyAssetURL) as? URL
if pathURL == nil {
print("#Warning!!! Track : \(item) is not playable.")
} else {
let trackInfo = SongItem()
trackInfo.index = index
trackInfo.mediaItem = item
let title = item.value(forProperty: MPMediaItemPropertyTitle) as? String ?? "<Unknown>"
let artistName = item.value(forProperty: MPMediaItemPropertyArtist) as? String ?? "<Unknown>"
trackInfo.songName = title
trackInfo.artistName = artistName
trackInfo.isSelected = false
trackInfo.songURL = item.value(forProperty: MPMediaItemPropertyAssetURL) as? URL
allSongItems?.append(trackInfo)
index += 1
}
}
// Sort the songs alphabetically
let sortedArray: [SongItem]? = allSongItems?.sorted {
$0.songName!.localizedCompare($1.songName!) == .orderedAscending
}
allSongItems?.removeAll()
if let arr = sortedArray {
allSongItems?.append(contentsOf: arr)
}
}
