Sorry in advance if this has been answered, I've searched repeatedly here and the in the apple docs, but haven't found out what is causing this problem. I have a iOS app that is driven by a 'layout' file that contains references to the content. I wanted to create a command line tool to optimize the content and modify the layout file if need. For example, by tiling an image and replacing it in the layout by the tiles.
I thought to create my first ever OSX tool and used the newest Xcode to create a CoreFoundation project, which gives me a main.c like this:
#include <CoreFoundation/CoreFoundation.h>
int main (int argc, const char * argv[])
{
CFShow(CFSTR("Hello, World!\n"));
return 0;
}
which builds fine. I thought to use some of the NS* classes to start working with the command line args, but as soon as I included the Foundation framework and added this line:
#include <Foundation/Foundation.h>
I started to get tons of build errors. I think I'm missing something basic, here, but I can't see it! Did I choose the wrong template? Is there a better one? Or, what's the problem with using Foundation here?
You need to set the file language to Objective C for it to compile. Either that or rename main.c in main.m
