以下是我在CollectionViewController中附加到main.storyboard中的CollectionView的代码：

class CollectionViewController: UICollectionViewController {
 
var Array = [String]()
 
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view,typically from a nib.
 
    Array = ["1","2","3","4","5"]
}
 
override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}
 
func collectionView(collectionView: UICollectionView,numberOfItemsSection section: Int) -> Int {
    return Array.count
}
 
override func
    collectionView(collectionView: UICollectionView,cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
 
        var cell = collectionView.dequeueReusableCellWithReuseIdentifier("cell",forIndexPath: indexPath) as! UICollectionViewCell
 
        var button = cell.viewWithTag(1) as! UIButton
        button.titleLabel?.text = Array[indexPath.row]
 
        return cell
}

}

这些是Collection View Controller的连接：
