ViewHelper

Autolayout and View Animation Helper for Swift 3.0. Mimimum requirements: Swift 3 and IOS 9 Supported: IOS and Apple TV

Animations

// Required
view.animate(.Shake, curve:.EaseInOutBack)
// With optionals
view.animate(.Shake, curve:.EaseInOutBack, duration:0.8, delay:0, force:1, damping:0.7,velocity:1, fromRotation:0, fromScale:1.5, fromX:0, fromY:0)

Auto Layout

letbox=UIView(autoLayout:true)
view.addSubview(box)
box.backgroundColor =UIColor.redColor()
box.width(100)
box.height(100)
box.center(to: view)
view.layoutIfNeeded()

Chainable functions

100 pixel view pinned to the center of another view

view.width(100).height(100).center(to: view)

Compression & Hugging

view.horizontalCompressionPriority(UILayoutPriorityDefaultHigh)
view.horizontalHuggingPriority(UILayoutPriorityDefaultLow)

NSLayoutConstraints

You can have access to the NSLayoutConstraints by using pin() or applyAttribute.

// Pinning to an item
letwidthConstraint= view.pin(.Width, to: view, attribute:.Height, constant:0, multiplier:0.5, relation:.LessThanOrEqual)

// Applying an attribute
letwidthConstraint= view.applyAttribute(.Width, constant:100, multiplier:0.5, relation:.Equal)

UIView Extension

Prepping for Auto Layout

If a view is already in place with frames, prepForAutoLayout() will remove it from view, enable Auto Layout and place back in view.

view.prepForAutoLayout()

Prepping for Animation

If a view uses auto layout but you need to animate it using frames, prepForAnimation() will remove from view, disable auto layout and place back in view.

view.prepForAnimation()
