Library: Main storage: Cache files, can be generated in real-time.

TMP: The temporary file is stored and is automatically cleared when it is closed.

Go to the folder according to the previous home path to view the folder you want to clear under library/caches/default/

nsstring *path = @ "library/caches/default/ Com.hackemist.SDWebImageCache.default ";

3. Stitching into a complete path

nsstring *newpath = [Home stringbyappendingpathcomponent:p ath];
