pod 'RacoonKit'

Then type pod install command in project folder via terminal.

pod install

Usage

Adding subviews

You may add any UIView based components as just as an array to container view:

let newView = UIView()
let otherNewView = UIView()
view.addSubviews(views: newView, otherNewView)

Placing a view

Defining view's margins with an array in single line:

let newView = UIView()
newView.setMargins(.top(value: 8), .left(value: 8), .right(value: 8), .bottom(value: 8))

Defining a margin between two views:

newView.setMarginTo(view: otherNewView, of: .top(value: 8))
newView.setMarginTo(view: otherNewView, of: .right(value: 8))
newView.setMarginTo(view: otherNewView, of: .left(value: 8))
newView.setMarginTo(view: otherNewView, of: .bottom(value: 8))

Height and width:

newView.setHeight(100)
newView.setWidth(125)
newView.setWidthEqualToSuperview()
newView.setHeightEqualToSuperview()
newView.setWidthEqualTo(view: view)
newView.setHeightEqualTo(view: view)
newView.setWidthEqualTo(views: view, view, view)
newView.setHeightEqualTo(views: view, view, view)

Setting 'Equal' and 'Priority' to a constraint

With new RacoonFormat, you can define priority and equal properties. Use setMarginWith(formats: RacoonFormat...) method to define multiple constraints.

firstView.setMarginWith(formats: RacoonFormat(constant: .top(value: 0)))
firstView.setMarginWith(formats: RacoonFormat(constant: .left(value: 10), equality: RacoonEquality.greaterOrEqual))
firstView.setMarginWith(formats: RacoonFormat(constant: .right(value: 20), equality: RacoonEquality.lessOrEqual, priority: RacoonPriority.high))

Use RacoonFormat for setting relationships between two views:

firstView.setMarginTo(view: secondView, with: RacoonFormat(constant: .top(value: 0)))
firstView.setMarginTo(view: secondView, with: RacoonFormat(constant: .left(value: 10), equality: RacoonEquality.greaterOrEqual))
firstView.setMarginTo(view: secondView, with: RacoonFormat(constant: .right(value: 20), equality: RacoonEquality.lessOrEqual, priority: RacoonPriority.high))
