Cocoapods Compatible

A lightweight library for layout views with Swift.

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Install via cocoapods

ZLayout is available through CocoaPods. To install
it, simply add the following line to your Podfile:

platform :ios, "8.0"
use_frameworks!
pod "ZLayout"

Example

Catogram interface

Let’s replicate Instagram feed UI, but with more dose of cats.
After all setups of subviews this is what we should do for layout our views.

let ratio: CGFloat = 5/7
self.headerView.anchor(toParentEdge: .top, gravity: .center, width: .superView, height: 60)
self.avatarContainerView.anchor(toParentEdge: .left, gravity: .center, offset: CGPoint(x: 16, y: 0))
self.moreOptions.anchor(toParentEdge: .right, gravity: .center, width: .auto, height: .auto, offset: CGPoint(x: -16, y: 0))
self.nameLabel.alignAndFill(on: .rightOffset(16), relativeTo: avatarContainerView, withGravity: .center, stretchTo: moreOptions, trailingPadding: 16, size: .auto)
self.contentImageView.align(on: .bottom, relativeTo: headerView, withGravity: .center, width: .superView, height: .value(self.width * ratio))
self.actionsView.align(on: .bottom, relativeTo: contentImageView, withGravity: .center, width: .superView, height: 50)
self.likeImageVIew.anchor(toParentEdge: .left, gravity: .center, width: .auto, height: .auto, offset: CGPoint(x: 16, y: 0))
self.favoritesImageVIew.anchor(toParentEdge: .right, gravity: .center, width: .auto, height: .auto, offset: CGPoint(x: -16, y: 0))
self.commentImageVIew.align(on: .rightOffset(16), relativeTo: likeImageVIew, withGravity: .center, width: .auto, height: .auto)
self.viewsCountLabel.align(on: .bottom, relativeTo: actionsView, withGravity: .leftOffset(16), width: .auto, height: .auto)
self.textLabel.align(on: .bottomOffset(6), relativeTo: viewsCountLabel, withGravity: .left, width: .auto, height: .auto)
self.viewsAllCommentsLabel.align(on: .bottomOffset(3), relativeTo: textLabel, withGravity: .left, width: .auto, height: .auto)
self.dateLabel.align(on: .bottomOffset(3), relativeTo: viewsAllCommentsLabel, withGravity: .left, width: .auto, height: .auto)

Not bad for 20 lines of code!
There are few ways to layout your view via ZLayout.

Anchoring

To place a view relative to the parent you can use anchoring. The most simple example is anchoring to center of parent.

view1.anchor(toParentEdge: .centerParent, width: 50, height: 50)

anchorCenter Example

To fill superview you can use specific case of ZLayoutEdge named .all. In this case width and height parameters will be ignored.

view1.anchor(toParentEdge: .all, inset: UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5))

superView Example

You can do the same via .superView value for width and height.

centerView1.anchor(toParentEdge: .centerParent, width: .superView, height: .superView, inset: UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5))

Gravity means corner which will be centered by default but you can pick one of these:
.center,.top,.bottom,.left or .right

view1.anchor(toParentEdge: .left, width: 50, height: 50, offset: CGPoint(x: 5, y: 0))
view2.anchor(toParentEdge: .right, width: 50, height: 50, offset: CGPoint(x: -5, y: 0))
view3.anchor(toParentEdge: .top, width: 50, height: 50, offset: CGPoint(x: 0, y: 5))
view4.anchor(toParentEdge: .bottom, width: 50, height: 50, offset: CGPoint(x: 0, y: -5))

superView Example

Alignment

Another way to layout your views is align view relative to another one.

view1.align(on: .leftOffset(20), relativeTo: centerView, withGravity: .top, width: 80, height: 30)
view2.align(on: .leftOffset(20), relativeTo: centerView, withGravity: .center, width: 80, height: 30)
view3.align(on: .leftOffset(20), relativeTo: centerView, withGravity: .bottom, width: 80, height: 30)
view4.align(on: .rightOffset(20), relativeTo: centerView, withGravity: .top, width: 80, height: 30)
view5.align(on: .rightOffset(20), relativeTo: centerView, withGravity: .center, width: 80, height: 30)
view6.align(on: .rightOffset(20), relativeTo: centerView, withGravity: .bottom, width: 80, height: 30)
view7.align(on: .topOffset(20), relativeTo: centerView, withGravity: .left, width: 30, height: 80)
view8.align(on: .topOffset(20), relativeTo: centerView, withGravity: .right, width: 30, height: 80)
view9.align(on: .topOffset(20), relativeTo: centerView, withGravity: .center, width: 30, height: 80)
view10.align(on: .bottomOffset(20), relativeTo: centerView, withGravity: .left, width: 30, height: 80)
view11.align(on: .bottomOffset(20), relativeTo: centerView, withGravity: .right, width: 30, height: 80)
view12.align(on: .bottomOffset(20), relativeTo: centerView, withGravity: .center, width: 30, height: 80)

Alignment Example

Also you can stretch view to another after alignment via alignAndFill method

view1.anchor(toParentEdge: .top, width: .superView, height: 20)
view2.anchor(toParentEdge: .bottom, width: .superView, height: 20)
view3.alignAndFill(on: .bottomOffset(5), relativeTo: topView, withGravity: .center, stretchTo: bottomView, trailingPadding: 5, size: 20)

Here size means width or height, it depends on alignment type.
