Hi
I wrote a base64 encoder/decoder category on NSData and NSString and
have been using it without problem for almost two years. Suddenly,
today, when I tried to use it in a new project, Xcode is telling me
four of the utility functions defined in the same file as the
NSCategories are "undefined symbols." I have no clue why this suddenly
started becoming a problem for Xcode, because as recently as a month
ago, I created a project that used these categories and got zero
"undefined symbol" errors. I've not done any Xcode or system upgrades
since last using the class.
What could be causing this? The symbols are literally defined inside
the file where Xcode says they aren't available. Anyone have an idea
why Xcode isn't seeing functions in the exact file it's compiling?
Thanks for any help
