Rubber band slider list

Case study of the RBSliderList. The RB is short for RubberBand. And its made by utilizing a a custom built ==animation engine== that delivers ==60FPS== butter smooth motion. It supports ==Rich interaction== combined with running tween animation. Apple doesn’t provide this combo so it had to be made. The RBSliderList is the first component to use this animation engine.




StyleManager.addStylesByURL("~/Desktop/css/list.css")/*load the related style-sheets*/

let dp = DataProvider(FileParser.xml("~/Desktop/scrollist.xml"))/*load xml data to add to the DataProvider*/
let section = self.addSubView(Section(200, 200, self, "listSection")) as! Section/*adds some visual space around the component*/
sliderList = section.addSubView(RBSliderList(140,120,24,dp,section)) as? RBSliderList
