AutoLayout

swift3.0轻量级的自动布局

用法

1.将UIView_AutoLayout.swift拖入工程

2.代码如下：

  //MARK: 最基础的
  let myView = self.view.createSubView()
  //距离父控件左100，右100，上20，高60
  myView.left(100).right(100).top(20).height(100)
  myView.backgroundColor = UIColor.red

  //MARK: 由子控件确定父控件大小
  let myView = self.view.createSubView()
  //距离父控件左100，右100，上20
  myView.left(100).right(100).top(20)
  myView.backgroundColor = UIColor.red
  
  let myIv = myView.createSubImageView()
  myIv.left(20).right(20).top(20).height(60)
  myIv.backgroundColor = UIColor.green
  myIv.image = UIImage(named: "IMG_5108.JPG")
  myIv.contentMode = .scaleAspectFit

  let mylabel = myView.createSubLabel()
  //由于mylabel距离父控件的下间距和与上边myIv的距离已经确定而且label会根据自身文字属性确定自身高度，因此父控件myView的高度就被确定了
  mylabel.left(20).right(20).bottom(20, toItem: myIv).bottom(20)
  //但是如果label换成普通view需要明确告知其高度即 mylabel.left(20).right(20).bottom(20, toItem: myIv).bottom(20).height(x)
  myLabel.numberOfLines = 0
  myLabel.text = "test"
  mylabel.backgroundColor = UIColor.green

  //MARK: 实现scrollview的自动布局
  let myScv = self.view.createSubScrollView()
  myScv.left(100).right(100).bottom(30, toItem: myView).height(150)
  myScv.backgroundColor = UIColor.brown
  
  //
  let vContent = myScv.createSubView()
  //MARK: 需要给定宽度
  vContent.left(0).right(0).top(0).bottom(0).width(self.view.bounds.size.width - 200)
  
  let myLabel1 = vContent.createSubLabel()
  myLabel1.left(10).right(10).top(10)
  myLabel1.font = UIFont.systemFont(ofSize: 12)
  myLabel1.numberOfLines = 0
  myLabel1.text = testStr
  myLabel1.backgroundColor = UIColor.green
  
  let myIv1 = vContent.createSubImageView()
  myIv1.left(20).right(20).bottom(20, toItem: myLabel1).bottom(40).height(100)
  myIv1.backgroundColor = UIColor.green
  myIv1.image = UIImage(named: "IMG_5108.JPG")
  myIv1.contentMode = .scaleAspectFit

  //MARK: 实现view的自动布局，适用于tableviewCell
  let vContent1 = self.view.createSubView()
  vContent1.left(100).right(100).bottom(30, toItem: myScv)
  vContent1.backgroundColor = UIColor.cyan
  
  let myLabel2 = vContent1.createSubLabel()
  myLabel2.left(10).right(10).top(10)
  myLabel2.font = UIFont.systemFont(ofSize: 12)
  myLabel2.numberOfLines = 0
  myLabel2.text = testStr
  myLabel2.backgroundColor = UIColor.green
  
  let myIv2 = vContent1.createSubImageView()
  myIv2.left(20).right(20).bottom(20, toItem: myLabel2).bottom(20).height(100)
  myIv2.backgroundColor = UIColor.green
  myIv2.image = UIImage(named: "IMG_5108.JPG")
  myIv2.contentMode = .scaleAspectFit
