创建一个类:PlayCollectionViewController.swift

//cell重用标识@H_502_5@
private@H_502_5@ let@H_502_5@ reuseIdentifier = "reuseIdentifier"@H_502_5@
class PlayCollectionViewController: UICollectionViewController {

    //页面个数@H_502_5@
    private@H_502_5@ let@H_502_5@ pageCount = 6@H_502_5@
    //布局对象(自定义布局)@H_502_5@
    private@H_502_5@ var@H_502_5@ layout: UICollectionViewFlowLayout = PlayLayout()

    init() {
        super.init(collectionViewLayout: layout)
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented"@H_502_5@)
    }

    override@H_502_5@ func viewDidLoad() {
        super.viewDidLoad()

        //注册cell@H_502_5@
        collectionView?.registerClass(NewfearureCell.self,forCellWithReuseIdentifier: reuseIdentifier)
    }

    //MARK: - UICollectionDataSource@H_502_5@
    override@H_502_5@ func collectionView(collectionView: UICollectionView,numberOfItemsInSection section: Int) -> Int {
        return@H_502_5@ pageCount
    }

    override@H_502_5@ func collectionView(collectionView: UICollectionView,cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {

        let@H_502_5@ cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier,forIndexPath: indexPath) as@H_502_5@! NewfearureCell
        cell.imageIndex = indexPath.item
        return@H_502_5@ cell
    }
}

自定义CollectionView的cell

//MARK: - 在这里我们依然在(PlayCollectionViewController.swift的文件中)自定义collectionViewCell@H_502_5@
class NewfearureCell: UICollectionViewCell {

    //保存图片索引@H_502_5@
    private@H_502_5@ var@H_502_5@ imageIndex:Int? {
        didSet {
            //根据页码创建图片名字(需要每张图片的名称只有最有最有一个数不同)@H_502_5@
            iconView.image = UIImage(named: "image_\(imageIndex!)"@H_502_5@)
        }
    }

    override@H_502_5@ init(frame: CGRect) {
        super.init(frame: frame)

        //初始化UI@H_502_5@
        setupUI()
    }
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented"@H_502_5@)
    }

    private@H_502_5@ func setupUI@H_502_5@() {

        //添加子控件到contentView@H_502_5@
        contentView.addSubview(iconView)
        //布局子控件位置(填充屏幕)@H_502_5@
        iconView.xmg_Fill(contentView)
    }

    //MARK: 懒加载@H_502_5@
    private@H_502_5@ lazy var@H_502_5@ iconView = UIImageView()
}

继承UICollectionViewFlowLayout,自定义布局

private@H_502_5@ class@H_502_5@ PlayLayout: UICollectionViewFlowLayout {

    //重写系统准备布局的方法@H_502_5@
    override@H_502_5@ func prepareLayout() {

        //设置layout布局@H_502_5@
        itemSize = UIScreen.mainScreen().bounds.size
        minimumInteritemSpacing = 0@H_502_5@
        minimumLineSpacing = 0@H_502_5@
        scrollDirection = UICollectionViewScrollDirection.Horizontal

        //设置其他属性@H_502_5@
        collectionView?.showsHorizontalScrollIndicator = false@H_502_5@
        collectionView?.bounces = false@H_502_5@
        collectionView?.pagingEnabled = true@H_502_5@
    }
}
