Read Facebook POP Framework notes (1), facebookpop

In this series of articles, I will primarily record my experience reading third-party code and try to analyze and dissect a framework independently. I have read some third-party code before, but in fact it is not very helpful for my own growth, because I did not understand the essence of the code because I did not carefully read it. I hope to learn the excellent framework step by taking notes and posting them to my blog. The first framework is POP, followed by AFN and SDWebImage. The reason why I read POP first is mainly because I know little about POP and curiosity drives me to read POP first.
