It's like AutoLayoutKit but written in Swift. For pure Swift projects. And it's super simple.
Features
- concise, simple and convenient API
- raw AutoLayout power
- no black magic involved
- fully documented
- completely unit-tested
Have a look at the Changelog for more details.
Requirements
- iOS 8.0+
- Xcode 6.3
Bonus: Support for iOS 7.0+ and/or tvOS
Although the cocoapods isn't able to install Manuscript for your iOS 7.0+ app or for your tvOS app (yet), you can use still Manuscript. Just follow the 'manual' installation or add Manuscript as a framework project to your workspace (that's what I do).
What it looks like
Manuscript.layout(myButton) { c in
c.set(.Height, to: 60.0)
c.set(.Width, to: 60.0)
c.make(.Bottom, equalTo: self.view, s: .Bottom, minus: 10.0)
c.make(.CenterX, equalTo: self.view, s: .CenterX)
}
Usage
A few examples on how to use Manuscript.
Center and set size
Center a UIView 'childView' in self.view and make it 30 by 30 in size
Manuscript.layout(childView) { c in
c.make(.CenterX, equalTo: self.view, s: .CenterX)
c.make(.CenterY, equalTo: self.view, s: .CenterY)
c.set(.Width, to: 30.0)
c.set(.Height, to: 30.0)
}
The same, but using the convenience methods
Manuscript.layout(childView) { c in
c.centerIn(self.view)
c.setSize(CGSize(width: 30.0, height: 30.0))
}
Align all edges of a view to a superview
Align a UIView 'container' to all edges of self.view
Manuscript.layout(container) { c in
c.make(.Left, equalTo: self.view, s: .Left)
c.make(.Right, equalTo: self.view, s: .Right)
c.make(.Top, equalTo: self.view, s: .Top)
c.make(.Bottom, equalTo: self.view, s: .Bottom)
}
The same, but using the convenience methods
Manuscript.layout(container) { c in
c.alignAllEdges(to: self.view)
}
Align all sides with insets
Align a UIView 'container' to all edges of self.view and leave a 30 point margin around the container.
Manuscript.layout(container) { c in
c.make(.Left, equalTo: self.view, s: .Left, plus: 30.0)
c.make(.Right, equalTo: self.view, s: .Right, minus: 30.0)
c.make(.Top, equalTo: self.view, s: .Top, plus: 30.0)
c.make(.Bottom, equalTo: self.view, s: .Bottom, minus: 30.0)
}
The same, but using convenience methods.
Manuscript.layout(container) { c in
c.alignAllEdges(to: self.view, withInsets: UIEdgeInsets(top: 30.0, left: 30.0, bottom: 30.0, right: 30.0))
}
Use LayoutGuides
Make use of the LayoutGuides provided by UIViewController.
Manuscript.layout(container) { c in
c.make(.Left, equalTo: self.view, s: .Left)
c.make(.Right, equalTo: self.view, s: .Right)
c.make(.Top, equalTo: self.topLayoutGuide, s: .Baseline)
c.make(.Bottom, equalTo: self.bottomLayoutGuide, s: .Baseline)
}
Hairlines
There is a utility method to create hairlines which takes the screen scale into account.
Manuscript.layout(mySeparatorLine) { c in
c.make(.Left, equalTo: self.view, s: .Left)
c.make(.Right, equalTo: self.view, s: .Right)
c.make(.Top, equalTo: self.topLayoutGuide, s: .Baseline)
// sets the .Height to 1.0 on non-retina displays and to 0.5 on retina displays
c.makeHorizontalHairline()
}
Work with the created Layout Constraints
The functions make
and set
return a tuple of type LayoutItem
which translates to
(constraint: NSLayoutConstraint?, targetItem: UIView?)
. The 'constraint' is the created
NSLayoutConstraint
, the 'targetItem' is the view to which the NSLayoutConstraint
was added. It
is the nearest common superview of the UIView
s involved.
Manuscript.layout(container) { c in
self.leftConstaint = c.make(.Left, equalTo: self.view, s: .Left).constraint
self.rightConstaint = c.make(.Right, equalTo: self.view, s: .Right).constraint
self.topConstaint = c.make(.Top, equalTo: self.topLayoutGuide, s: .Baseline).constraint
self.bottomConstaint = c.make(.Bottom, equalTo: self.bottomLayoutGuide, s: .Baseline).constraint
}
Afterwards, just modify the constraint's constant and apply the changes (this is plain AutoLayout).
UIView.animateWithDuration(0.6) { in
self.topConstraint?.constant = 100
self.view.layoutIfNeeded()
}
Convenience Methods
The convenience methods return arrays of the mentioned tuples. These will be dictionaries or tuples in the future as well to provide easier access to the created constraints. Until then, check the code for the order of the returned constraints.
Installation
As for now, you can use Carthage or CocoaPods to install Manuscript using a dependency manager or do it manually.
Carthage
To integrate Manuscript into your Xcode project using Carthage, specify it in your Cartfile
:
github "floriankrueger/Manuscript"
CocoaPods
Make sure your Podfile
contains all of the following lines.
use_frameworks!
platform :ios, '8.0'
pod 'Manuscript'
Then run pod install
.
Manually
To do it 'by hand' take the following files and add them to your project:
Source/Manuscript.swift
Source/LayoutProxy.swift
