fatal error: Index out of range

Question

I want to show 25 of the songs I have in my library. This is my code:

var allSongsArray: [MPMediaItem] = []
let songsQuery = MPMediaQuery.songsQuery()

func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return 25 //allSongsArray.count
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("cell")
    let items = allSongsArray[indexPath.row]
    cell?.textLabel?.text = items.title
    cell?.detailTextLabel?.text = items.artist
    cell?.imageView?.image = items.artwork?.imageWithSize(imageSize)

    return cell!
}

When I run this, it crashes, because:

fatal error: Index out of range

I tried to change the numberOfRowsInSection to allSongsArray.count, but it ends up with the same error.

Answer 1

You should return allSongsArray.count and to avoid being returned empty cells use yourTableView.reloadData after you fill your allSongsArray.
