Create a custom cell

class CustomCell: UICollectionViewCell {

    @IBOutlet weak var label: UILabel!
    @IBOutlet weak var delButton: UIButton!
    @IBOutlet weak var addButton: UIButton!

    @IBAction func addTapped(sender: AnyObject) {
       delButton.removeFromSuperview()
       addButton.removeFromSuperview()
    }
}

Typical CollectionView Controller

class ViewController: UICollectionViewController {

    override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return 10;
    }

    override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
        let cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell", forIndexPath: indexPath) as! CustomCell

        cell.label.text = "Cell \(indexPath.row)"

        return cell
    }

}

And your button will gone, when you hit them
