# SwiftGif [](https://developer.apple.com/swift/) [](https://github.com/Carthage/Carthage) [](http://cocoadocs.org/docsets/SwiftGifOrigin) [](https://github.com/Carthage/Carthage) [](https://travis-ci.org/bahlo/SwiftGif) A small `UIImage` extension with gif support.  ## Usage ```swift // An animated UIImage let jeremyGif = UIImage.gif(name: "jeremy") // A UIImageView with async loading let imageView = UIImageView() imageView.loadGif(name: "jeremy") // A UIImageView with async loading from asset catalog(from iOS9) let imageView = UIImageView() imageView.loadGif(asset: "jeremy") ``` ## Installation ### CocoaPods Install [CocoaPods](http://cocoapods.org) with the following command: ```bash gem install cocoapods ``` Integrate SwiftGif into your Xcode project by creating a `Podfile`: ```ruby platform :ios, '9.0' use_frameworks! target '<Your Target Name>' do pod 'SwiftGifOrigin', '~> 1.7.0' end ``` Run `pod install` to build your dependencies. ### Carthage Install [Carthage](https://github.com/Carthage/Carthage) with [Homebrew](http://brew.sh/) using the following command: ```bash brew update brew install carthage ``` Add the following line to your `Cartfile` to add SwiftGif: ```ogdl github "bahlo/SwiftGif" ~> 1.7.0 ``` Run `carthage update` to build the framework and drag the built `SwiftGif.framework` into your Xcode project. ## How does it work? Easy, it does the following: 1. Find out the duration of every frame 2. Find the greatest common divisor 3. Add frames accordingly to the greatest common divisor to an array 4. Create an animated UIImage with the frames ## Testing ``` $ xcodebuild \ -project SwiftGif.xcodeproj \ -scheme SwiftGif \ -sdk iphonesimulator \ -destination "platform=iOS Simulator,name=iPhone 8" \ build test \ CODE_SIGNING_REQUIRED=NO CODE_SIGN_IDENTITY="" ``` # Inspiration This project is heavily inspired by [uiimage-from-animated-gif](https://github.com/mayoff/uiimage-from-animated-gif).
