As iOS can spontaneously remove the cache folder it seems like a bad idea to save the cached images in the cache folder since the SDWebImage cache mechanism knows when and which image to remove.
This happens a lot to our users, where they suddenly need to redownload all the images in the app even if it an image they downloaded 5 minutes ago.
How can I change the location of the cache of the sharedImageCached? and how to migrate the current cache to the new folder?
