For convenience, we added categories for UI elements like `UIImageView`, `UIButton`, `MKAnnotationView`. ## Features - [x] Categories for `UIImageView`, `UIButton`, `MKAnnotationView` adding web image and cache management - [x] An asynchronous image downloader - [x] An asynchronous memory + disk image caching with automatic cache expiration handling - [x] A background image decompression to avoid frame rate drop - [x] [Progressive image loading](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#progressive-animation) (including animated image, like GIF showing in Web browser) - [x] [Thumbnail image decoding](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#thumbnail-decoding-550) to save CPU && Memory for large images - [x] [Extendable image coder](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#custom-coder-420) to support massive image format, like WebP - [x] [Full-stack solution for animated images](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#animated-image-50) which keep a balance between CPU && Memory - [x] [Customizable and composable transformations](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#transformer-50) can be applied to the images right after download - [x] [Customizable and multiple caches system](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#custom-cache-50) - [x] [Customizable and multiple loaders system](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#custom-loader-50) to expand the capabilities, like [Photos Library](https://github.com/SDWebImage/SDWebImagePhotosPlugin) - [x] [Image loading indicators](https://github.com/SDWebImage/SDWebImage/wiki/How-to-use#use-view-indicator-50) - [x] [Image loading transition animation](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#image-transition-430) - [x] A guarantee that the same URL won't be downloaded several times - [x] A guarantee that bogus URLs won't be retried again and again - [x] A guarantee that main thread will never be blocked - [x] Modern Objective-C and better Swift support - [x] Performances! ## Supported Image Formats - Image formats supported by Apple system (JPEG, PNG, TIFF, BMP, ...), including [GIF](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#gif-coder)/[APNG](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#apng-coder) animated image - HEIC format from iOS 11/macOS 10.13, including animated HEIC from iOS 13/macOS 10.15 via [SDWebImageHEICCoder](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#heic-coder). For lower firmware, use coder plugin [SDWebImageHEIFCoder](https://github.com/SDWebImage/SDWebImageHEIFCoder) - WebP format from iOS 14/macOS 11.0 via [SDWebImageAWebPCoder](https://github.com/SDWebImage/SDWebImage/wiki/Advanced-Usage#awebp-coder). For lower firmware, use coder plugin [SDWebImageWebPCoder](https://github.com/SDWebImage/SDWebImageWebPCoder) - Support extendable coder plugins for new image formats like BPG, AVIF. And vector format like PDF, SVG. See all the list in [Image coder plugin List](https://github.com/SDWebImage/SDWebImage/wiki/Coder-Plugin-List) ## Additional modules and Ecosystem In order to keep SDWebImage focused and limited to the core features, but also allow extensibility and custom behaviors, during the 5.0 refactoring we focused on modularizing the library. As such, we have moved/built new modules to [SDWebImage org](https://github.com/SDWebImage). #### SwiftUI [SwiftUI](https://developer.apple.com/xcode/swiftui/) is an innovative UI framework written in Swift to build user interfaces across all Apple platforms. We support SwiftUI by building a brand new framework called [SDWebImageSwiftUI](https://github.com/SDWebImage/SDWebImageSwiftUI), which is built on top of SDWebImage core functions (caching, loading and animation). The new framework introduce two View structs `WebImage` and `AnimatedImage` for SwiftUI world, `ImageIndicator` modifier for any View, `ImageManager` observable object for data source. Supports iOS 13+/macOS 10.15+/tvOS 13+/watchOS 6+ and Swift 5.1. Have a nice try and provide feedback! #### Coders for additional image formats - [SDWebImageWebPCoder](https://github.com/SDWebImage/SDWebImageWebPCoder) - coder for WebP format. iOS 8+/macOS 10.10+.
