ALKit

Easy to use AutoLayout wrapper around NSLayoutConstraints.

Requirements

  • Swift 4.2+
  • iOS 8.0+
  • tvOS 9.0+

Install

CocoaPods

use_frameworks!
pod 'ALKit'

Manual

Copy the ALKit folder into your project

Usage

Init

Create UIView instances from either storyboard or programmatically. Don't forget to set view.translatesAutoresizingMaskIntoConstraints = false if you are creating them programmatically.

Wraper

The main function of all kit. Wraps addConstraint: method of autolayout.

func pin(
  inView inView: UIView? = nil,
  edge: NSLayoutAttribute,
  toEdge: NSLayoutAttribute,
  ofView: UIView?,
  withInset: CGFloat = 0) {
  let view = inView ?? ofView ?? self
  view.addConstraint(NSLayoutConstraint(
      item: self,
      attribute: edge,
      relatedBy: .Equal,
      toItem: ofView,
      attribute: toEdge,
      multiplier: 1,
      constant: withInset))
}

Example

box.fill(toView: view)

blue.pinTop(toView: box, withInset: 10)
blue.fillHorizontal(toView: box, withInset: 10)
blue.pinHeight(90)

red.pinBottom(toView: box, withInset: 10)
red.fillHorizontal(toView: box, withInset: 10)
red.pinHeight(90)

yellow.pinToTop(ofView: red, withOffset: 10)
yellow.pinCenterX(toView: red)
yellow.pinSize(width: 50, height: 50)

That would be look like this:
