Access User-Defined Setting in Xcode

Question

Hi everyone,

If i added a user-defined setting in my build configuration, how can i read that setting in my objective-C files. I have two files in my project debug.plist and release.plist. I want my MainApp.m file to read one of these files based on which build configuration is running. I set up a user-defined setting named "filename" in both Debug and Release configuration point to the appropriate file. But i dont know how my MainApp.m file and read the filename variable from the current running configuration. Thank you.

Your code can't read arbitrary build settings. You need to use preprocessor macros.

EDIT: For example, in the target settings for the Debug configuration, you could add DEBUGGING=1 in the Preprocessor Macros build setting, and not define DEBUGGING in the Release configuration. Then in your source code you could do things like:

#if DEBUGGING
  use this file
#else
  use the other one
#endif
