PLEASE READ DESCRIPTION BEFORE BUYING

Unfortunatly the app got some bad comments from buyers, who obviously did not read the description and as a result expect other than found in the description below.

Animated GIF Tool comes handy for MacOS and iOS developers, implementing rich-media applications, including sprite animations, delivered as GIF files.
 
There exists no ready-to-use Cocoa component to play back GIF animations (besides using UI/NSWebViews, which is not a perfect solution).

Here is where Animated GIF Tool kicks in. It takes a GIF file, extracts frame and loop count as well as each frames timing information and stores that in an easy to use Property List file.
The image information can either be stored as a sequence of PNG or JPG files, or can be embedded as NSData within the Property List as well. The data can be loaded into NSImage or UIImage objects with there original (imageFromData:) method.

You can download the source files for SAAnimatedImageView, a ready to use subclass of UIImageView/NSImageView from the the Animated GIF Tool  website.
