How to change value defined constants in Objective C

Question

I've declared constant as follows:

#define OPENIN_DIR_PATH_FORMAT_STRING L"%@"              

Now how should I change the value for OPENIN_DIR_PATH_FORMAT_STRING here with %@

Answer 1

#define is not making constant it's the macro definition. If you want to change this macro you might do #undef and #define it again. But I strongly discourage you from messing around with macros :)
