However, you can enable the full GIF support by using the built-in GIF coder. See [GIF coder](https://github.com/rs/SDWebImage/wiki/Advanced-Usage#gif-coder) +- **Important**: FLAnimatedImage only works on the iOS platform. For macOS, use `NSImageView` with `animates` set to `YES` to show the entire animated images and `NO` to only show the 1st frame. For all the other platforms (tvOS, watchOS) we will fallback to the backwards compatibility feature described above + +## Installation + +There are three ways to use SDWebImage in your project: +- using CocoaPods +- using Carthage +- by cloning the project into your repository + +### Installation with CocoaPods + +[CocoaPods](http://cocoapods.org/) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. See the [Get Started](http://cocoapods.org/#get_started) section for more details. + +#### Podfile +``` +platform :ios, '7.0' +pod 'SDWebImage', '~> 4.0' +``` + +If you are using Swift, be sure to add `use_frameworks!` and set your target to iOS 8+: +``` +platform :ios, '8.0' +use_frameworks! +``` + +#### Subspecs + +There are 4 subspecs available now: `Core`, `MapKit`, `GIF` and `WebP` (this means you can install only some of the SDWebImage modules. By default, you get just `Core`, so if you need `WebP`, you need to specify it). + +Podfile example: +``` +pod 'SDWebImage/WebP' +``` + +### Installation with Carthage (iOS 8+) + +[Carthage](https://github.com/Carthage/Carthage) is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods. + +To install with carthage, follow the instruction on [Carthage](https://github.com/Carthage/Carthage) + +#### Cartfile +``` +github "rs/SDWebImage" +``` + +### Installation by cloning the repository +- see [Manual install](Docs/ManualInstallation.md) + +### Import headers in your source files + +In the source files where you need to use the library, import the header file: + +```objective-c +#import <SDWebImage/UIImageView+WebCache.h> +``` + +### Build Project + +At this point your workspace should build without error. If you are having problem, post to the Issue and the +community can help you solve it. + +## Author +- [Olivier Poitrey](https://github.com/rs) + +## Collaborators +- [Konstantinos K.](https://github.com/mythodeia) +- [Bogdan Poplauschi](https://github.com/bpoplauschi) +- [Chester Liu](https://github.com/skyline75489) +- [DreamPiggy](https://github.com/dreampiggy) + +## Licenses + +All source code is licensed under the [MIT License](https://raw.github.com/rs/SDWebImage/master/LICENSE). + +## Architecture + +<p align="center" > + <img src="Docs/SDWebImageClassDiagram.png" title="SDWebImage class diagram"> +</p> + +<p align="center" > + <img src="Docs/SDWebImageSequenceDiagram.png" title="SDWebImage sequence diagram"> +</p> -- Gitblit v1.8.0
