Open Source Objective C Animation Software

FLAnimatedImage is a performant animated GIF engine for iOS. Plays multiple GIFs simultaneously with a playback speed comparable to desktop browsers. Honors variable frame delays. Behaves gracefully under memory pressure. Eliminates delays or blocking during the first playback loop. Interprets the frame delays of fast GIFs the same way modern browsers do. It's a well-tested component that powers all GIFs in Flipboard. FLAnimatedImage is a well-encapsulated drop-in component. Simply replace your UIImageView instances with instances of FLAnimatedImageView to get animated GIF support. There is no central cache or state to manage. It's flexible to integrate in your custom image loading stack and backwards compatible to iOS 9. It uses ARC and the Apple frameworks QuartzCore, ImageIO, MobileCoreServices, and CoreGraphics.

Pop is an extensible animation engine for iOS, tvOS, and OS X. In addition to basic static animations, it supports spring and decay dynamic animations, making it useful for building realistic, physics-based interactions. The API allows quick integration with existing Objective-C or Swift codebases and enables the animation of any property on any object. It's a mature and well-tested framework that drives all the animations and transitions in Paper. By adding the project to your project and adding pop.embedded framework to the Embedded Binaries section on the General tab of your app's target, you can set up pop in seconds! The Pop interface is implemented as a category addition on NSObject. Any NSObject or subclass can be animated. There are four concrete animation types: spring, decay, basic and custom.

You can easily add an awesome animated context menu to your app. You are welcome to see the sample of the project for a fully operating sample in the Example folder. To customize menu items side positions you can specify a 'menuItemsSide' property. When it is set to 'Right' the first cell will be opened from right to left and the selected cell will be closed and vice versa and when it set to 'Left' the first cell will be opened from left to right and the selected cell will be closed vice versa. Default - Right. Also, to customize menu items appearance direction you can specify the 'menuItemsAppearanceDirection' property. Default - FromTopToBottom.

Jazz Hands is a simple keyframe-based animation framework for UIKit. Animations can be controlled via gestures, scroll views, KVO, or ReactiveCocoa. Jazz Hands is used extensively in IF and DO by IFTTT for iPhone and iPad, most famously in the app intro. Open JazzHandsDemo.xcworkspace to see a simple demonstration of moving, scaling, fading, and transforming views in a scrolling app intro. To run the example project, clone the repo, and run pod install from the Example directory. Looking to incorporate Jazz Hands into your Swift project? Check out RazzleDazzle, our brand new scrolling keyframe animations library reimagined in Swift. As a bonus, because it's built on top of the animations library, you can even tell JazzHands that you'd like one of your views to show up on multiple pages while other views scroll past, with a single call to keepView:onPages. To see the new JazzHands 2.0 AutoLayout magic in action, check out the example project.

Custom animated pull-to-refresh that can be easily added to UIScrollView.

Shimmer is a lightweight Objective-C library by Facebook that adds an elegant, animated shimmering effect to views—used as a subtle loading indicator, such as in the Paper app. There's also an example project. In the example, you can swipe horizontally and vertically to try various shimmering parameters, or tap to start or stop shimmering. (To build the example locally, you'll need to open FBShimmering.xcworkpace rather than the .xcodeproj.) Shimmer uses the -[CALayer mask] property to enable shimmering, similar to what's described in John Harper's 2009 WWDC talk (unfortunately no longer online). Shimmer uses CoreAnimation's timing features to smoothly transition "on-beat" when starting and stopping the shimmer.

View Controller Transitions Library is a collection of iOS7 animation controllers and interaction controllers, providing flip, fold and all kinds of other transitions. With iOS 7 you can easily create custom view controller transitions that can be used in a range of contexts (push, pop, modal, etc.) This project provides a library of custom animations which can be dropped directly into your project. It also has a number of 'interaction controllers' which can be used with any of the custom animations in order to make your transitions interactive. Animation and interaction controllers are entirely independent, this means you can wire up any interaction controller with any animation controller, which is pretty awesome. When you indicate that a custom transition should be used, you provide an animation controller. This class performs the required animation, then informs the framework when it has completed.

macSVG is a MIT-licensed open-source macOS app for designing HTML5 SVG 1.1 (Scalable Vector Graphics) art and animation. macSVG can produce dynamic, high-quality graphics and animation for HTML5 web views that work on most major desktop and mobile platforms, including iOS, Android, macOS, Microsoft Windows and Linux. macSVG uses the standard macOS WebKit framework for interactive editing and rendering of SVG documents, in addition to several Cocoa plug-in bundles for editing SVG elements and attributes. Apple’s free Xcode system is required to build the macOS application from the source code. Most of the application source code is written in Objective-C language, but a Swift language target has been added recently for a plug-in editor bundle. To build macSVG.app, open "macSVG.xcworkspace" in Xcode, set the build target to "macSVG Debug", build and run.
