实现了什么功能?
- 1.类似于选择电影票的效果
- 2.自动轮播
- 3.无限轮播
- 4.非当前显示view具有缩放和透明的特效
- 5.页面滚动的方向分为横向和纵向
仿照UITableView使用代理实现传值
protocol PageFlowViewDelegate : NSObjectProtocol{
func sizeForPageInFlowView(flowView : PageFlowView) -> CGSize
/// 滚动到了某一列
func didScrollToPage(pageNumber : Int,inFlowView flowView : PageFlowView)
/// 点击了第几个cell
///
/// - Parameters:
/// - subView: 点击的控件
/// - subIndex: 点击控件的index
func didSelectCell(subView : IndexBannerSubiew,subViewIndex subIndex : Int)
}
protocol PageFlowViewDataSource : NSObjectProtocol{
/// 返回显示View的个数
func numberOfPagesInFlowView(flowView : PageFlowView) -> Int
/// 给某一列设置属性
///
/// - Parameters:
/// - flowView: <#flowView description#>
/// - index: <#index description#>
/// - Returns: <#return value description#>
func cellForPageAtIndex(flowView : PageFlowView,atIndex index : Int) -> IndexBannerSubiew
}
使用示例
// 模拟器原因,底部会有残影,真机测试没有
let pageFlowView = PageFlowView.init(frame: CGRect.init(x: 0, y: 72, width: kScreenW, height: kScreenW*9/16))
pageFlowView.backgroundColor = UIColor.white
pageFlowView.delegate = self
pageFlowView.dataSource = self
pageFlowView.minimumPageAlpha = 0.1
pageFlowView.isCarousel = true
pageFlowView.orientation = .vertical
pageFlowView.isOpenAutoScroll = true
//初始化pageControl
let pageControl = UIPageControl.init(frame: CGRect.init(x: 0, y: pageFlowView.bounds.height-32, width: kScreenW, height: 8))
pageFlowView.pageControl = pageControl
pageFlowView.addSubview(pageControl)
pageFlowView.reloadData()
view.addSubview(pageFlowView)
