Gifu

Adds performant animated GIF support to UIKit. If you're looking for the Japanese prefecture, click here.

How?

Gifu uses a UIImageView subclass and an animator that keeps track of frames and their durations.

It uses CADisplayLink to animate the view and only keeps a limited number of resized frames in-memory, which exponentially minimizes memory usage for large GIF files (+300 frames).

The figure below summarizes how this works in practice. Given an image containing 10 frames, Gifu will load the current frame (red), pre-load the next two frames in this example (orange), and nullify all the other frames to free up memory (gray):

Install

If you use Carthage, add this to your cartfile: github "kaishin/gifu".

If your prefer Git submodules or want to support iOS 7, you want to add the files in source to your Xcode project.

Usage

Start by instantiating an AnimatableImageView either in code or Interface Builder, then call animateWithImage(named:) or animateWithImageData(data:) on it.

let imageView = AnimatableImageView(frame: CGRect(...))
imageView.animateWithImage(named: "mugen.gif")

You can stop the animation anytime using imageView.stopAnimatingGIF(), and resume it using imageView.startAnimatingGIF().

The isAnimatingGIF() method returns the current animation state of the view if it has an animatable image.

See the full documentation.
