Question

What folder do I place a file to pass in as a command line argument in xcode 4?
I’m placing my list.txt file in the folder that xcode created but when I test for the existence of the file I’m getting NULL.I thought that when I edit the scheme and add list.txt
as an argument that the file would be passed in.

Either you should pass the full path to the file, or you need to figure out the working directory that Xcode launches the executable in:

NSString *workingDir = [[[NSProcessInfo processInfo] environment] objectForKey:@"PWD"];
NSLog(@"working directory = %@", workingDir);

and put your file in that dir.
