Swift-加载SDCycleBannerView库的轮播图

轮播图的实现采用OC库的SDCycleBannerView;

说明：

项目以Pod库的形式引入；

  pod 'SDCycleScrollView','~> 1.82'

必要步骤：

1.导入SDCycleScrollView 库；

import SDCycleScrollView

2.初始化轮播对象:

lazy var bannerView:SDCycleScrollView = {
        let rect = CGRect(origin:CGPoint.init(x: 12, y: 15), size: CGSize.init(width: view.frame.size.width, height: 170))
        let bannerView:SDCycleScrollView = SDCycleScrollView(frame: rect, shouldInfiniteLoop: true, imageNamesGroup: ["home_banner_default"])
        bannerView.autoScrollTimeInterval = 3.0
        bannerView.showPageControl = true
        bannerView.hidesForSinglePage = false
        bannerView.pageControlStyle =  SDCycleScrollViewPageContolStyleClassic
        bannerView.pageDotColor = UIColor.lightGray
        if #available(iOS 11.0, *) {
            bannerView.currentPageDotColor = UIColor.init(named: "GreenColor")
        } else {
            // Fallback on earlier versions
            bannerView.currentPageDotColor = UIColor.green
        }       
        bannerView.delegate = self
        return bannerView
    }()

3.自定义轮播图的Cell

class CarouselsCollectionViewCell: SDCollectionViewCell {}

4.处理回调数据；

遵守协议

class DBViewController: UIViewController,SDCycleScrollViewDelegate {}

设置代理对象：

bannerView.delegate = self

func setupCustomCell(_ cell1: UICollectionViewCell!, for index: Int, cycleScrollView view: SDCycleScrollView!) {}
    func customCollectionViewCellClass(for view: SDCycleScrollView!) -> AnyClass! {
        return CarouselsCollectionViewCell.self
    }
