本文介绍如何在iOS应用中设置滚动视图的属性，包括背景颜色、内容尺寸、滚动特性等，实现平滑的页面切换效果。

    
    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.backgroundColor = UIColor.cyan
        self.navigationItem.title = "滚动视图"
        self.view.addSubview(self.scrollView)
    }
    
  fileprivate  lazy var scrollView:UIScrollView = {
        
        let Scroll:UIScrollView = UIScrollView.init(frame: UIScreen.main.bounds)
        Scroll.contentSize = CGSize.init(width:kScreenW*3,height:kScreenH)
        Scroll.contentOffset = CGPoint.init(x: 0 , y: 0)
        self.automaticallyAdjustsScrollViewInsets = false
        Scroll.showsHorizontalScrollIndicator = false
        Scroll.showsVerticalScrollIndicator = false
        Scroll.isPagingEnabled = true
        Scroll.isScrollEnabled = true
        Scroll.bounces = false
        Scroll.delegate = self    
        return Scroll
    }()
