效果圖

Swift,電影票,自動輪播

實現了什么功能?

1.類似于選擇電影票的效果

2.自動輪播

3.無限輪播

4.非當前顯示view具有縮放和透明的特效

5.頁面滾動的方向分為橫向和縱向

仿照UITableView使用代理實現傳值

protocol PageFlowViewDelegate : NSObjectProtocol{ func sizeForPageInFlowView(flowView : PageFlowView) -> CGSize /// 滾動到了某一列 func didScrollToPage(pageNumber : Int,inFlowView flowView : PageFlowView)  /// 點擊了第幾個cell /// /// - Parameters: /// - subView: 點擊的控件 /// - subIndex: 點擊控件的index func didSelectCell(subView : IndexBannerSubiew,subViewIndex subIndex : Int)}protocol PageFlowViewDataSource : NSObjectProtocol{ /// 返回顯示View的個數 func numberOfPagesInFlowView(flowView : PageFlowView) -> Int  /// 給某一列設置屬性 /// /// - Parameters: /// - flowView: <#flowView description#> /// - index: <#index description#> /// - Returns: <#return value description#> func cellForPageAtIndex(flowView : PageFlowView,atIndex index : Int) -> IndexBannerSubiew}

使用示例

// 模擬器原因,底部會有殘影,真機測試沒有let pageFlowView = PageFlowView.init(frame: CGRect.init(x: 0, y: 72, width: kScreenW, height: kScreenW*9/16))pageFlowView.backgroundColor = UIColor.whitepageFlowView.delegate = selfpageFlowView.dataSource = selfpageFlowView.minimumPageAlpha = 0.1pageFlowView.isCarousel = truepageFlowView.orientation = .verticalpageFlowView.isOpenAutoScroll = true//初始化pageControllet pageControl = UIPageControl.init(frame: CGRect.init(x: 0, y: pageFlowView.bounds.height-32, width: kScreenW, height: 8))pageFlowView.pageControl = pageControlpageFlowView.addSubview(pageControl)pageFlowView.reloadData()view.addSubview(pageFlowView)
