The Core of SDWebImage v5.6 Architecture	2020-02-22 23:08:12 +0800	SourceCode iOS cache SourceCode	iOS Objc	土土Edmond木

This article is based on SDWebImage 5.6. Why i write this article, cause i found that SD's API is constantly iterating, and many of the structures are different from earlier versions. Here is to make a record. We will start from the top of the API's level list below, force on the entire framework's data flow.
