复盘发现,是因为app重启,丢失了所有processor的内容,导致缓存清理不掉。
把processor融合到图片缓存key,而不提供单纯的清理某张图片派生出所有图片缓存的api,面对一些常见场景的时候,有些无力。。。

这个场景,我个人现在的建议是,你可以为每个URL设置一个 cache
(伪代码,不一定正确):
var caches = [String: ImageCache]()
func imageCacheForURL(_ url: URL) -> ImageCache {
caches[url.absoluteString] ?? {
let c = ImageCache(name: url.absoluteString)
caches[url.absoluteString] = c
return c
}()
}
let imageView: UIImageView
imageView.kf.setImage(with: url, options: [.processor(processor1), .targetCache(imageCacheForURL(url))])
imageView.kf.setImage(with: url, options: [.processor(processor2), .targetCache(imageCacheForURL(url))])
// Later
imageCacheForURL(url).clearCache()
