Place UILabel center of parent

I am trying to put

UILable
at the center of each cell of
UICollectionView
.

Here is my code:

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

// Configure the cell
cell.backgroundColor = UIColor.brownColor()

let title = UILabel(frame: CGRectMake(cell.bounds.midX, cell.bounds.midY, cell.bounds.size.width, 20)) //
title.text = "ddd"
title.textColor = UIColor.whiteColor()

// title.center = cell.center

cell.contentView.addSubview(title)

// let xCenterConstraint = NSLayoutConstraint(item: title, attribute: .CenterX, relatedBy: .Equal, toItem: cell, attribute: .CenterX, multiplier: 1, constant: 0)
// let yCenterConstraint = NSLayoutConstraint(item: title, attribute: .CenterY, relatedBy: .Equal, toItem: cell, attribute: .CenterY, multiplier: 1, constant: 0)
// let leadingConstraint1 = NSLayoutConstraint(item: title, attribute: .Leading, relatedBy: .Equal, toItem: cell, attribute: .Leading, multiplier: 1, constant: 20)
// let trailingConstraint1 = NSLayoutConstraint(item: title, attribute: .Trailing, relatedBy: .Equal, toItem: cell, attribute: .Trailing, multiplier: 1, constant: -20)
// cell.addConstraints([xCenterConstraint, yCenterConstraint, leadingConstraint1, trailingConstraint1])
// title.centerXAnchor.constraintEqualToAnchor(cell.centerXAnchor).active = true
// title.centerYAnchor.constraintEqualToAnchor(cell.centerYAnchor).active = true


return cell
}


The output:

Seems I need to change my code, so what am I missing?
