How to define a macro globally in Objective-C? (2 answers)

Closed 9 years ago.

I want to define a logging macro that I can use in all my source files, but I don't want to import the file in which I defined the macro every time? So, I am just curios whether it is possible to make a macro globally available without importing the file in which it is defined every time?

Answer 1

Declare the macro in the #ifdef __OBJC__ section of your AppName-Prefix.pch.
