How to set image using Kingfisher when image url d

问题:

How to retrieve correct image using Kingfisher when image url did not change but image changed such as Twitter or GitHub.

SDWebImage has a option [SDWebImageRefreshCached] to solve the problem.

   /**
     * Even if the image is cached, respect the HTTP response cache control, and refresh the image from remote location if needed.
     * The disk caching will be handled by NSURLCache instead of SDWebImage leading to slight performance degradation.
     * This option helps deal with images changing behind the same request URL, e.g. Facebook graph api profile pics.
     * If a cached image is refreshed, the completion block is called once with the cached image and again with the final image.
     *
     * Use this flag only if you can't make your URLs static with embedded cache busting parameter.
