title: "Reachability.h" "Reachability.m gives an Apple mach-o linker error while adding them
body: <p>I am creating an iPhone application, and I am using RestKit api to connect to the server. I am facing a problem whenever I add the <code>Reachability.m</code> and <code>Reachability.h</code> into the second <code>UIViewController</code> of the project. I tried making a new .m file in Xcode4 and now I get an Apple macho-linker (id) error on all tabst. I added it to the first <code>UIViewcontroller</code> it works normally, but when I try to add it to any other forms I receive this error.</p>
