ios public static const equiv

Question

I'm trying to accomplish a C style version of public static const

What I tried doing already:

ClassA.h

• extern const int FEATURES;

ClassA.m

• #define THE_CONST 123

ClassB.b

• #import ClassA.h
• initWithFrame
  • FEATURES

Xcode does not through a runtime error, but rather a build error of undefined symbols for architecture i386: "_THE_CONST", referenced from: ...

How can I share an extern const to for another class to use as well?

Answer 1

ClassA.h

• extern const int FEATURES;

ClassA.m

• const int FEATURES = <your const value here>;
