An integer constant is a value that is determined at compile time and cannot be changed at run time. An integer constant expression is an expression that is composed of constants and evaluated to a constant at compile time. An integer constant expression is an expression that is composed of ...
the key must be a constant integer expression. Which was vague but -as I read it- allowed things like const k float64 = 3.0 to be keys, since k is, arguably, a "constant integer". The spec was updated in CL 30474, fix to issue #16679, and now says: The key must be a non-ne...
If you set the value of the constant in the .m, it is not visible by other translation units that only include the .h file. The value of the constant must be known at compile time to be able to be used in a case within a switch. 意思是:当使用extern在.h中声明常量,在.m中给该常...

A constant's value must be in the range of representable values for its type. A constant's type determines which conversions are performed when the constant is used in an expression or when the minus sign (-) is applied. This list summarizes the conversion rules for integer constants. The ...
