Concorde
Concorde is a powerful image loading and caching library for iOS. It provides an efficient and easy-to-use way to load images asynchronously, handle caching, and support advanced features like download prioritization.
Why use Concorde?
Concorde offers several advantages over other image loading libraries for iOS:
1. Performance
Concorde is designed to deliver optimal performance when loading images. It uses advanced techniques like prefetching, lazy loading, and memory and disk caching to ensure smooth and fast image loading, even for large images or complex image layouts.
2. Easy Integration
Integration with Concorde is straightforward. Simply add the library to your project using Cocoapods or Carthage, and you’re ready to start loading and caching images. Concorde seamlessly integrates with popular networking libraries like Alamofire and AFNetworking, making it a breeze to incorporate into existing projects.
3. Advanced Features
Concorde includes a range of powerful features to enhance your image loading experience. Some of these features include:
– Download prioritization: Easily prioritize images based on their importance.
– Image compression: Concorde automatically compresses images to optimize loading time and reduce storage space.
– Offline caching: Images are cached on the device to provide a seamless experience even when the device is offline.
– Animated GIF support: Concorde can efficiently load and display animated GIFs.
Getting Started
To start using Concorde, follow these simple steps:
1. Installation
Concorde can be installed using either Cocoapods or Carthage. Pick your preferred method, then add the appropriate dependencies to your Podfile or Cartfile, and run the installation command.
“`
# Using Cocoapods
pod ‘Concorde’
# Using Carthage
github “contentful/concorde”
“`
2. Initialization
Now that Concorde is installed, you need to initialize it in your AppDelegate to ensure its proper functioning:
“`swift
// In AppDelegate.swift
import Concorde
func application(_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Initialize Concorde
ImageLoader.initialize()
return true
}
“`
3. Loading Images
You can effortlessly load images using Concorde. Simply provide the image URL and the image view where you want to display the image. Concorde will handle the rest, including caching and asynchronous loading.
“`swift
import Concorde
let url = URL(string: “https://www.example.com/image.jpg”)!
Concorde.shared.load(url, into: imageView)
“`
Advanced Usage
Concorde provides additional functionality to maximize control over your image loading:
1. Download Prioritization
Concorde allows you to specify priority levels for image downloads. You can easily adjust the download priority based on factors like scroll position or user interactions.
“`swift
import Concorde
let url = URL(string: “https://www.example.com/image.jpg”)!
Concorde.shared.load(url, into: imageView) { image in
// Image has been loaded
// For example, lower priority of subsequent downloads
if image != nil {
Concorde.shared.setPriority(.low, for: url)
}
}
“`
3. Image Compression
Concorde automatically compresses images to optimize loading time and reduce storage space. If you want to customize the compression quality, you can do so using the `compressionQuality` property.
“`swift
import Concorde
let url = URL(string: “https://www.example.com/image.jpg”)!
Concorde.shared.compressionQuality = 0.5
Concorde.shared.load(url, into: imageView)
“`
