I am not quite sure about your use case and image updating mechanism, to me, it is not quite a perfect case to use Kingfisher. If you just need to refresh the image every time, you can use the forceRefresh
to ask Kingfisher loads from your url
instead of seeking it from the cache.
Behind the story, when you are using KFImage(url)
to display an image, it in fact tries to download it from the url
and caches it with the combination of the cacheKey
(by default, the URL string) and the processors identifier. That is because we just want to store the final result instead of the medium artifacts. However, in your code (setImage(_:_:
), you are trying to check and cache the image again with the cacheKey
alone. With any processors (here resizing
and downsampling
), the actually used cache key in this method does not equal to the one used by KFImage(url)
. That means, you are indeed clearing the image and caching it again, but under a different key that KFImage(url).resizing. downsampling
is not using.
After each image creation, I will use Kingfisher to save it to the device's cache (I don't know if this is safe for data or not because I'm just a novice with Swift and Kingfisher).
If the images are important, I have to say it is not a good idea. These content are user created and cannot be restored. As the ImageCache
's name suggests, it is possible that these cached images being purged (due to system behavior, disk space not enough, normally expires, etc). That is also a reason I said "it is not quite a perfect case to use Kingfisher" at the beginning.

So in my case, would it be reasonable to save the image in FileManager and use KingFisher to display the image via the local url?
Based on your experience, please give me a solution. Please!
