Auto Layout made easy with the Custom Layout.

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate CustomLayout into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '12.0'
use_frameworks!

target '<Your Target Name>' do
    pod 'CustomLayout', '~> 1.0.1'
end

Then, run the following command:

$ pod install

Swift Package Manager

Swift Package Manager is a tool for managing the distribution of Swift code. It’s integrated with the Swift build system to automate the process of downloading, compiling, and linking dependencies.

Xcode 11+ is required to build CustomLayout using Swift Package Manager.

dependencies: [
    .package(url: "https://github.com/MnkGitBox/CustomLayout.git", .upToNextMajor(from: "1.0.1"))
]

Manually

If you prefer not to use either of the aforementioned dependency managers, you can integrate CustomLayout into your project manually.

Usage

You can call layout.activate method provided by the Custom Layout library.

• Without Custom Layout

view.addSubview(redView)

view.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([redView.leadingAnchor.constraint(equalTo: view.leadingAnchor,
                                                                    constant: 50),
                            redView.trailingAnchor.constraint(equalTo: view.trailingAnchor,
                                                                    constant: -50),
                            redView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor,
                                                                    constant: 40),
                            redView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor,
                                                                    constant: -20)])

• With Custom Layout

view.addSubview(redView)

redView.layout.activate([.leading(constant: 50), .traling(constant: -50), .top(constant: 40, safeAreaAlign: true), .bottom(constant: -20, safeAreaAlign: true)])

Layout to sibling views

Custom Layout not only helps to layout subviews to its super view. We can use it to layout view components with other views who share the same ancestors.

greenView.layout.activate(to: [view : [.bottom(constant: -2, safeAreaAlign: true), .traling(constant: -20)],
                                    redView : [.leadingToTraling(constant: -10), .topToBottom(constant: 20)]])
