CGLayout

Introduction to CGLayout

CGLayout is a powerful layout engine that simplifies the process of creating complex and dynamic layouts in  iOS. Using CGLayout, developers can easily manage and handle view hierarchies and resizing behaviors in an efficient manner.

Main Features of CGLayout

Some of the main features of CGLayout are as follows:

  • Efficient handling of iOS view hierarchies
  • Simplified layout creation with less code
  • Support for complex and dynamic layouts
  • Easy configuration of layout elements
  • Good performance in complex scenarios

Installing CGLayout

To install CGLayout, you need to use CocoaPods, which is a dependency manager for Swift and Objective-C Cocoa projects.

# CocoaPods
pod 'CGLayout'

Basic Usage of CGLayout

Below is a basic example of how to use CGLayout:

// Create a layout
let layout = Layout.create { (make) in
    make.leading.equalToSuperview().offset(10)
    make.trailing.equalToSuperview().offset(-10)
    make.top.equalToSuperview().offset(20)
}

// Apply the layout to a view
view.cg.applyLayout(layout)

Constraints Management

CGLayout provides a convenient way to manage constraints. Here’s an example:

// Create a layout and store its constraints
let layout = view.cg.makeLayout { (make) in
    make.leading.equalToSuperview().offset(10)
}
    
// Update constraints later
layout.update { (make) in
    make.leading.equalToSuperview().offset(20)
}

Conclusion

With the introduction of CGLayout, designing complex and dynamic layouts in iOS has never been easier. It simplifies the process by providing an understandable and straightforward way to manage the view hierarchies and offers high performance. With CGLayout, you’ll be building your next level iOS applications in no time.
