YYWebImage

YYWebImage is an Objective-C asynchronous image loading framework for iOS that focuses on efficient downloading, decoding, caching, and displaying of remote or local images in mobile apps, designed to be a high-performance alternative to popular solutions like SDWebImage. It integrates tightly with the rest of the YYKit ecosystem and uses YYCache for memory and disk caching and YYImage for animated image support, which means it can handle formats such as WebP, APNG, and GIF smoothly in your UI components. The framework provides easy-to-use category extensions for UIImageView, UIButton, CALayer, and other UI elements so developers can assign a URL and let the library handle the download, decode, and display process asynchronously without blocking the main thread. It supports progressive and interlaced image decoding, which improves perceived loading performance by showing partial images earlier.
