简单几行代码就可实现无限自动轮播

    //图片数组
    let imagesArr = ["second.jpeg","third.jpeg","fourth.jpeg","fifth.jpeg","sixth.jpeg","seventh.jpeg","eighth.jpg"]
    
    //创建轮播视图
    let scrollView = CKCScrollView(frame: CGRect(x: 0, y: 20, width: view.width, height: 200))
    view.addSubview(scrollView)
    
    //展示图片
    scrollView.imageArray = imagesArr

    //是否自动轮播
    scrollView.isAutoScroll = true
    
    //切换时间间隔（可不设置，默认三秒）
    //scrollView.autoScrollDeley = 1
    
    //点击屏幕中间图片回调
    scrollView.blockWithClick = {(senderCLick : Int) ->() in
    
        label.text = "点击了第\(senderCLick + 1)张图片"
    
    }
