Usage and specification of IOS macro definitions

Macro definitions are used in many ways, such as defining heights, judging iOS systems, tool classes, and documentation such as file paths and server-side API interfaces. In order to quickly locate and understand the function of a macro, it is best to put it in a specific header file when defined
