How do I save files to $(PROJECT_DIR) from objective-c code?

Question

I have code which generates resources which I want to save in a subdirectory of my $(PROJECT_DIR). How do I get the real path from this environment variable in code?

Answer 1

open the projects build settings and add SAVEPATH=@\"$(PROJECT_DIR)\" to the preprocessor macros.
Then you can get the project directory like this:

NSString *projectDir = SAVEPATH;
