does any of you have example code (or a link to it) of how to retrieve all music albums or artist from the iPod media library?
Thanks in advance!
Use a MPMediaQuery:
MPMediaQuery *allAlbumsQuery = [MPMediaQuery albumsQuery];
NSArray *allAlbumsArray = [allAlbumsQuery collections];
The allItems array does now contain MPMediaItemCollections, grouping is done by album. Now you can walk through the arrays.
for (MPMediaItemCollection *collection in allAlbumsArray) {
MPMediaItem *item = [collection representativeItem];
}
