TinyLayout

A µframework with the purpose to be the most brief and readable way to declare or apply a AutoLayout NSLayoutConstraint in Swift.

What can TinyLayout do for you?

With TinyLayout you can stop doing this:

let superview = self.view
let view = UIView()
view.setTranslatesAutoresizingMaskIntoConstraints(false)
superview.addSubview(view)

superview.addConstraint(NSLayoutConstraint(item: view, attribute: .Top, relatedBy: .Equal, toItem: superview, attribute: .Top, multiplier: 1, constant:0))

And start doing this:

let superview = self.view
let view = UIView()
superview.addSubview(view)

(view,.Top)|=|(superview,.Top)

Integration

Carthage

If you’re using Carthage, simply add TinyLayout to your Cartfile:

github "rubenroques/TinyLayout"

Usage

The simplest version, without multipliers or constraints.

//Add a NSLayoutConstraint to the view.superview
(view,.Top)|=|(superview,.Top)

//Create a NSLayoutConstraint variable
let layoutConstraint = (view,.Top)|=|&(superview,.Top)

The default values are constant = 0 and multiplier = 1.

With a constant value.

//Add a NSLayoutConstraint to the view.superview
(view,.Top)|=|(superview,.Top, 50)
(view,.Left)|=|(superview,.Left, -100)

//Create a NSLayoutConstraint variable
let layoutConstraintTop = (view,.Top)|=|&(superview,.Top, 50)
let layoutConstraintLeft = (view,.Left)|=|&(superview,.Left, -100)

With a constant value and a multiplier.

//Add a NSLayoutConstraint to the view.superview
(view,.Top)|=|(superview,.Top, 1.2, 50)
(view,.Left)|=|(superview,.Left, 2, -100)

//Create a NSLayoutConstraint variable
let layoutConstraintTop = (view,.Top)|=|&(superview,.Top, 1.2, 50)
let layoutConstraintLeft = (view,.Left)|=|&(superview,.Left, 2, -100)

Roadmap

1. Finish Roadmap :)
2. ["You should be testing your library."] (http://guides.cocoapods.org/making/using-pod-lib-create.html#choosing-a-test-framework)
3. Create a typealias to avoid repeat the long tuples used in the functions parameter names
4. Improve demo app
5. Add support to fallback constrains using an array of UIView (view,.Top)|=|([superview, labelA, labelB],.Top)
6. Create func to set the NSLayoutConstraint priority in the declaration
7. Migrate from UIView to View to add support for AppKit
