Try this:

+ (UIImage *)animatedImageWithAnimatedGIFData:(NSData *)data duration:(NSTimeInterval)duration {
    return animatedImageWithAnimatedGIFReleasingImageSource(CGImageSourceCreateWithData(toCF data, NULL));
}


static UIImage *animatedImageWithAnimatedGIFReleasingImageSource(CGImageSourceRef source) {
    UIImage *image = animatedImageWithAnimatedGIFImageSource(source);
    CFRelease(source);
    return image;
}



static UIImage *animatedImageWithAnimatedGIFImageSource(CGImageSourceRef source) {
//replace duration with ImageIO function
if (!source)
    return nil;

size_t count = CGImageSourceGetCount(source);
NSMutableArray *images = [NSMutableArray arrayWithCapacity:count];
NSTimeInterval time_duration = 0;
for (size_t i = 0; i < count; ++i) {
    CGImageRef cgImage = CGImageSourceCreateImageAtIndex(source, i, NULL);
    if (!cgImage)
        return nil;

    //get duration with ImageIO but not libgungif
    CFDictionaryRef properties = CGImageSourceCopyPropertiesAtIndex(source, i, NULL);
    if (properties) {
        CFDictionaryRef gifProperties = CFDictionaryGetValue(properties, kCGImagePropertyGIFDictionary);
        if (gifProperties) {
            CFNumberRef number = CFDictionaryGetValue(gifProperties, kCGImagePropertyGIFDelayTime);
            // Even though the GIF stores the delay as an integer number of centiseconds, ImageIO “helpfully” converts that to seconds for us.
            double delay = 0.f;
            CFNumberGetValue(number, kCFNumberDoubleType, &delay);
            delay = lrint(delay * 100.f);
            if (delay > 5.f) {
                time_duration += delay;
            }
            else {
                time_duration += 5.f;
            }
        }
        CFRelease(properties);
    }

    [images addObject:[UIImage imageWithCGImage:cgImage]];
    CGImageRelease(cgImage);
}

return [UIImage animatedImageWithImages:images duration:(time_duration / 100.f)];
}
