滚动视图(UIScrollView)

滚动视图的创建

let scr = UIScrollView(frame:CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height))

设置内容的区域的大小(滑动的区域)

scr.contentSize = CGSize(width: self.view.frame.size.width * 4, height: self.view.frame.size.height)    

把滚动视图添加到view

self.view.addSubview(scr)   

滚动视图的设置偏移量

scr.contentOffset = CGPoint(x: self.view.frame.size.width, y: 0)

滚动视图是否整页翻动,默认是不翻动

cr.isPagingEnabled = true

滚动视图触壁反弹(在UIScrollView的边界时在再拉拉不动了)

scr.bounces = false

滚动视图展示滑动条(true:显示滑动条 false:关闭滑动条)

scr.showsHorizontalScrollIndicator = true

滚动视图设置滑动条的颜色

scr.indicatorStyle = .black

滚动视图是否关闭拖拽

scr.isScrollEnabled = false
