Easy Auto Layout

UIKit Programmatic Constraints. Simplified!

Swift iOS UIKit UIView NSLayoutConstraint

This repository contains Swift extensions for the UIView class, providing developers with the capability to effortlessly implement programmatic view layouts and write concise constraint code.

Features

• pinToBounds: Pins the current view to the bounds of another view with customizable insets.
• pinTo: Pins the current view to another view with customizable constraints for width, height, and positioning.
• pinTo (side-based): Pins the current view to a specific side (top, bottom, leading, or trailing) of another view with customizable constraints.

Usage

To use these extensions in your project, follow these steps:

1. Copy the UIViewExtension.swift file into your Xcode project.
2. Use the desired extension methods on your UIView objects.

Example: pinToBounds (using Safe Area Layout Guide)

let view1 = UIView()
let view2 = UIView()

// Pin view2 to the bounds of view1 with insets on all sides
view2.pinToBounds(of: view1, leading: 10, trailing: 10, top: 10, bottom: 10)

Example: pinTo (relative to view)

let view1 = UIView()
let view2 = UIView()

// Pin view2 to view1 with width, height and centered positioning
view2.pinTo(view: view1, width: 200, height: 100, centerX: 0, centerY: 0)

Example: pinTo (side-based)

let view1 = UIView()
let view2 = UIView()

// Pin view2 to the top side of view1 with 20 units spacing and match the width of view1
view2.pinTo(side: .top, of: view1, height: 200, spacing: 20)

// Pin view2 to the leading side of view1 with 20 units spacing and match the height of view1
view2.pinTo(side: .leading, of: view1, width: 200, spacing: 20)
