SBAutoLayout
SBAutoLayout 是 UIView 的一个扩展，使得在 Swift 中无需编写冗长的自动布局语法即可轻松执行常见的自动布局操作。
一些示例
使用高度和宽度固定到父视图中心
view.pinWidth(100)
view.pinHeight(100)
view.pinToSuperviewCenter()
某些视图可以使用一行代码进行定位
view.pinToSuperviewAsTopStrip(height: 50)
所有方法都返回生成的约束。如果您以后需要删除或更改它们，这将非常方便。
let topConstraint = view.pinToSuperviewTop(margin: 60)
view.pinToSuperviewBottom(margin: 40)
view.pinToSuperviewLeading(margin: 15)
view.pinToSuperviewTrailing(margin: 15)
// ...Later
topConstraint.constant = 30
如果有多个视图呢？当然。
blueView.pinToSuperviewCenter()
blueView.pinHeight(100)
blueView.pinAspectRatio(width: 1, height: 1)
orangeView.pinToSuperviewCenterX()
orangeView.pinHeight(80)
orangeView.pinAspectRatio(width: 1, height: 1)
orangeView.pinAboveView(blueView, separation: 10)

func pinToSuperviewCenterY(offset: CGFloat = 0, priority: UILayoutPriority? = nil) -> NSLayoutConstraint
func pinToSuperviewCenter(priority: UILayoutPriority? = nil) -> [NSLayoutConstraint] // MARK:- Pin to other views
固定在其他视图上方或下方
func pinAboveView(_ otherView: UIView, separation: CGFloat = 0, priority: UILayoutPriority? = nil) -> NSLayoutConstraint
func pinBelowView(_ otherView: UIView, separation: CGFloat = 0, priority: UILayoutPriority? = nil) -> NSLayoutConstraint
固定到其他视图的左侧、右侧、 Leading 或 Trailing
