CollectionViewController逻辑错误？

Question

我正在尝试实现集合视图控制器。但是，由于一些随机的原因每次我运行iOS模拟器时图像都不会出现...而且，编译器不会给我任何错误...所以，我不知道我在这里缺少什么...

CollectionView控制器

import UIKit

let reuseIdentifier = "Cell"

class CollectionViewController: UICollectionViewController {

     var imagesCell : [String] = []

     @IBOutlet var collectionSaso: UICollectionView!

     override func viewDidLoad() {
        super.viewDidLoad()

    // Register cell classes
    self.collectionView.registerClass(UICollectionViewCell.self, forCellWithReuseIdentifier: reuseIdentifier)

    // Do any additional setup after loading the view.
    imagesCell = ["miEsposa.jpg", "miEsposa.jpg", "miEsposa.jpg"]
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

// MARK: UICollectionViewDataSource

override func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
    //#warning Incomplete method implementation -- Return the number of sections
    return 0
}


override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    //#warning Incomplete method implementation -- Return the number of items in the section
    return imagesCell.count
}

override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

    let cell = collectionSaso.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as CollectionViewCell

    // Configure the cell
    cell.imageHolder.image = UIImage(named: imagesCell[indexPath.item])
    return cell
}

CollectionViewCell

import UIKit

class CollectionViewCell: UICollectionViewCell {

    @IBOutlet weak var imageHolder: UIImageView!
}
