I know I'm very likely missing something extremely basic here but I'm stuck. Why does the following code produce a table view of each track's artist instead of the artists listed in groups (i.e. why is each artist listed 20-something times instead of being all grouped together so that each artist is only listed once)? I've tried both the collections and items versions mentioned below. What am I doing wrong? How do I fix this? Any help is appreciated. Thanks in advance...
var tableData = MPMediaQuery.artistsQuery()
override func viewDidLoad() {
super.viewDidLoad()
self.artistTableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.tableData.collections!.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell: UITableViewCell = self.artistTableView.dequeueReusableCellWithIdentifier("cell")! as UITableViewCell
let artist: MPMediaItem = tableData.items![indexPath.row]
//let artist: MPMediaItemCollection = tableData.collections![indexPath.row]
if artist.valueForProperty(MPMediaItemPropertyArtist) == nil {
cell.textLabel?.text = "Artist" as String
} else {
let artistName = artist.valueForProperty(MPMediaItemPropertyArtist) as! NSString
cell.textLabel?.text = artistName as String
}
return cell
}
