Welcome to ConstraintLib

ConstraintLib is a powerful library for iOS and macOS that simplifies Auto Layout and constraint management in your apps. With ConstraintLib, you can easily define and manage layout constraints without the need for writing verbose and complex code.


Key Features

  • Intuitive and easy-to-use API for defining Auto Layout constraints.
  • Support for constraint-based layout on both iOS and macOS platforms.
  • Dynamic and responsive layouts by utilizing ConstraintLib’s animation and constraint update features.
  • Automatic handling of constraint conflicts to ensure consistent and predictable layouts.
  • Compatibility with Swift and Objective-C projects.
  • Comprehensive documentation and examples to help you get started quickly.


Installation

To install ConstraintLib in your iOS or macOS project, follow these steps:

  1. Open your project in Xcode.
  2. Navigate to your target’s settings.
  3. Select the “General” tab.
  4. Scroll down to the “Frameworks, Libraries, and Embedded Content” section.
  5. Click on the “+” button to add a new framework.
  6. Search for “ConstraintLib” and select it from the list.
  7. Make sure to set the appropriate target membership for your project.
  8. Click “Finish” to complete the installation process.


Getting Started

To begin using ConstraintLib in your project, follow these steps:

  1. Import the ConstraintLib framework into your Swift or Objective-C file:


    2. “`swift
    import ConstraintLib
    “`

  2. Create an instance of the ConstraintView class:


    3. “`swift
    let constraintView = ConstraintView()
    “`

  3. Add your views to the constraint view:


    4. “`swift
    constraintView.addSubview(view1)
    constraintView.addSubview(view2)
    // Add more views as needed
    “`

  4. Define your layout constraints using ConstraintLib’s intuitive API:


    5. “`swift
    constraintView.addConstraints([
    view1.topAnchor.constraint(equalTo: constraintView.topAnchor, constant: 10),
    view1.leadingAnchor.constraint(equalTo: constraintView.leadingAnchor, constant: 20),
    view1.trailingAnchor.constraint(equalTo: constraintView.trailingAnchor, constant: -20),
    view1.heightAnchor.constraint(equalToConstant: 50),

    view2.topAnchor.constraint(equalTo: view1.bottomAnchor, constant: 10),
    view2.leadingAnchor.constraint(equalTo: constraintView.leadingAnchor, constant: 20),
    view2.trailingAnchor.constraint(equalTo: constraintView.trailingAnchor, constant: -20),
    view2.heightAnchor.constraint(equalToConstant: 30),
    ])
    “`

  5. Update your constraints as needed:


    6. “`swift
    // Update the constant of an existing constraint
    constraintView.updateConstraint(view1.trailingAnchor, constant: -10)

    // Add a new constraint
    constraintView.addConstraint(view2.bottomAnchor.constraint(equalTo: constraintView.bottomAnchor, constant: -10))
    “`

  6. Enjoy the convenience and power of ConstraintLib for managing your layout constraints!
