# AnimatedGIFImageSerialization



> This library is no longer maintained. 

> In iOS 13+ and macOS 10.15+, use [`CGAnimateImageAtURLWithBlock`](https://developer.apple.com/documentation/imageio/3333271-cganimateimageaturlwithblock) instead.



`AnimatedGIFImageSerialization` decodes an `UIImage` from

[Animated GIFs](http://en.wikipedia.org/wiki/Graphics_Interchange_Format),

following the API conventions of Foundation's `NSJSONSerialization` class.



By default, `UIImage` initializers can't decode animated images from GIF files.

This library uses swizzling to provide this functionality for you.

To opt out of this behavior,

set `ANIMATED_GIF_NO_UIIMAGE_INITIALIZER_SWIZZLING` in your build environment.

If you're using CocoaPods,

you can add this build setting to your `Podfile`:



```ruby

post_install do |r|

  r.pods_project.targets.each do |target|

    if target.name == 'AnimatedGIFImageSerialization' then

      target.build_configurations.each do |config|

        config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||=

          ['$(inherited)', 'ANIMATED_GIF_NO_UIIMAGE_INITIALIZER_SWIZZLING=1']

      end

    end

  end

end

```



## Usage



### Decoding



```objective-c

UIImageView *imageView = ...;

imageView.image = [UIImage imageNamed:@"animated.gif"];

```



![Animated GIF](https://raw.githubusercontent.com/mattt/AnimatedGIFImageSerialization/master/Example/Animated%20GIF%20Example/animated.gif)



### Encoding



```objective-c

UIImage *image = ...;

NSData *data = [AnimatedGIFImageSerialization animatedGIFDataWithImage:image

                                                              duration:1.0

                                                             loopCount:1

                                                                 error:nil];

```
