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 the macro can quickly locate and understand its function, we better in the definition of the time to put it into a specific header file, the following I would like to introduce some commonly used macros to classify, sub-file definition, I hope to be helpful.
Define a macro for a dimension class
