本文实例为大家分享了Swift实现广告栏滑动效果的具体代码，供大家参考，具体内容如下
创建一个类:PlayCollectionViewController.swift
//cell重用标识
private let reuseIdentifier = "reuseIdentifier"
class PlayCollectionViewController: UICollectionViewController {
//页面个数
private let pageCount = 6
//布局对象(自定义布局)
private var layout: UICollectionViewFlowLayout = PlayLayout()
init() {
super.init(collectionViewLayout: layout)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func viewDidLoad() {
super.viewDidLoad()
//注册cell
collectionView?.registerClass(NewfearureCell.self, forCellWithReuseIdentifier: reuseIdentifier)
}
//MARK: - UICollectionDataSource
override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return pageCount
}
override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! NewfearureCell
cell.imageIndex = indexPath.item
return 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
class NewfearureCell: UICollectionViewCell {
//保存图片索引
private var 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)
iconView.image = UIImage(named: "image_\(imageIndex!)")
}
}
override init(frame: CGRect) {
super.init(frame: frame)
//初始化UI
setupUI()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
private func setupUI() {
//添加子控件到contentView
contentView.addSubview(iconView)
//布局子控件位置(填充屏幕)
iconView.xmg_Fill(contentView)
}
//MARK: 懒加载
private lazy var iconView = UIImageView()
}
继承UICollectionViewFlowLayout,自定义布局
private class PlayLayout: UICollectionViewFlowLayout {
//重写系统准备布局的方法
override func prepareLayout() {
//设置layout布局
itemSize = UIScreen.mainScreen().bounds.size
minimumInteritemSpacing = 0
minimumLineSpacing = 0
scrollDirection = UICollectionViewScrollDirection.Horizontal
//设置其他属性
collectionView?.showsHorizontalScrollIndicator = false
collectionView?.bounces = false
collectionView?.pagingEnabled = true
}
}
