轮翻播放与查看是分开的，轮翻是是用 开源的SDCycleScrollView

这里是给出的是查看的：

如何使用：

var sliderGallery : FullScreenShowImageView!    var bannerCurrentIndex:Int = 0//图片轮播组件协议方法：获取内部scrollView尺寸func galleryScrollerViewSize() -> CGSize {        return CGSize(width: BWidth, height: BHeight/2)}    //图片轮播组件协议方法：获取数据集合func galleryDataSource() -> [String] {        return self.bannerView.imageURLStringsGroup as! [String]}    //点击事件响应func hiddenForCliked(index:Int){        if(bannerCurrentIndex != index){             self.bannerView.scrollToIndex(Int32(index))}        self.navigationController?.setNavigationBarHidden(false, animated: false)}func showImageGallery(index:Int){        //初始化图片轮播组件if(sliderGallery == nil){sliderGallery = FullScreenShowImageView(frame: CGRect(x: 0, y: 0, width: BWidth,height: BHeight),delegate:self)sliderGallery.currentIndex = indexsliderGallery.resetImageViewSource()            //将图片轮播组件添加到当前视图self.view.addSubview(sliderGallery)}else{sliderGallery.currentIndex = indexsliderGallery.resetImageViewSource()sliderGallery.hidden = false}        self.sliderGallery.presentViewAnimate()        self.navigationController?.setNavigationBarHidden(true, animated: false)}    //pragma -- SDCycleScrollViewDelegatefunc cycleScrollView(cycleScrollView: SDCycleScrollView!, didSelectItemAtIndex index: Int) {        print("--------index:(index)")bannerCurrentIndex = index       self.showImageGallery(index)}
