Layout

Layout is a UIView extension that simplifies AutoLayout.

Initialization

Constructing a layout may be done in three ways, using the static library, view instance methods, and a chaining context.

Static Library

To construct a layout using the static library, a parent view and child view are passed to the Grid method.

let parentView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 500))

let childView = UIView()

Layout.topLeft(parentView, child: childView, top: 50, left: 50)

View Instance Methods

To construct a layout using the view instance methods, a parentView passes in a childView to its grid method and then supplies the constraint values.

let parentView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 500))

let childView = UIView()

parentView.layout.topLeft(childView, top: 50, left: 50)

Chaining Context

To construct a layout using a chaining context, a parentView passes in a childView to its grid context method and then supplies the constraint values.

let parentView = UIView(frame: CGRect(x: 0, y: 0, width: 300, height: 500))

let childView = UIView()

parentView.layout(childView).top(50).left(50)

Canvas

Canvas is a UIView extension that provides a row and column based layout system.

Rows & Columns

Canvas uses rows and columns to layout views. The entire layout is calculated mathematically.

let btn1: UIButton = UIButton()
btn1.backgroundColor = .redColor()
btn1.setTitle("Button 1", forState: .Normal)

let btn2: UIButton = UIButton()
btn2.backgroundColor = .greenColor()
btn2.setTitle("Button 2", forState: .Normal)

let btn3: UIButton = UIButton()
btn3.backgroundColor = .blueColor()
btn3.setTitle("Button 3", forState: .Normal)

btn1.canvas.columns = 2

btn2.canvas.columns = 2

btn3.canvas.columns = 2

view.canvas.axis.columns = 6
view.canvas.interimSpace = 16
view.canvas.contentInsets = Insets(top: 100, left: 16, bottom: 100, right: 16)
view.canvas.views = [btn1, btn2, btn3]
