Question

I have filenames and such that are NSStrings. I have to keep typing them in and I may mistype and cause an error. How does the experienced objective C programmer handle this so they only type it in once?

Answer 1

In the header:

extern NSString * const kMyFile;

in the implementation file

NSString * const kMyFile = @"FileName.txt";

You get code completion on it this way.

Or, if it is only being used in one class and doesn’t need to be exposed in the header you could just do

static NSString * const kMyFile = @"FileName.txt";
