I'm trying to follow the Stanford iPhone class and am having a problem with the import command. <-- Total n00b question Basically, I have a implementation file called "WhatATool.m" and we were told to create a custom class called "PolygonShape". I did just that, via New File... > Objective C Class > I set the file name as "PolygoneShape.m" Kept the box checked to create the header file Kept the box checked to Target "WhatATool" And then at the top, right next to #import <Foundation/Foundation.h>, I put the line #import <PolygonShape.h>. But when I try to compile it, it says: "error: PolygonShape.h: No such file or directory" Why can't it find it? Do I have to do anything else to get it to work? The .m and .h files are both listed under the "source" folder on the left. I assume that it's got to be something stupid and small... but I just can't figure out what's going on. Structurally, all these files are in the same directory. Any thoughts?
