使用UICollectionView
import UIKit
class MyBannerView: UIView, UICollectionViewDelegate, UICollectionViewDataSource {
var dataList = Array<Any>()
var myCollectionView: UICollectionView?
override init(frame: CGRect) {
super.init(frame: frame)
let layout = UICollectionViewFlowLayout()
layout.itemSize = frame.size
layout.scrollDirection = .horizontal
layout.minimumLineSpacing = 0
layout.minimumInteritemSpacing = 0
myCollectionView = UICollectionView(frame: CGRect(x: 0, y: 0, width: frame.size.width, height: frame.size.height), collectionViewLayout: layout)
myCollectionView?.dataSource = self
myCollectionView?.delegate = self
myCollectionView?.isPagingEnabled = true
myCollectionView?.showsHorizontalScrollIndicator = false
myCollectionView?.bounces = false
myCollectionView?.register(UINib(nibName: "BannerCollectionViewCell", bundle: Bundle.main), forCellWithReuseIdentifier: "BannerCollectionViewCell")
addSubview(myCollectionView!)
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setDataList(data: Array<Any>) {
dataList = data
myCollectionView?.reloadData()
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
dataList.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "BannerCollectionViewCell", for: indexPath) as! BannerCollectionViewCell
cell.imageView.backgroundColor = indexPath.item % 2 > 0 ? .cyan : .purple
return cell
}
}
