Hi, I have a fully functioning iPhone app (developed in debug mode) that I was about to submit to the app store a few minutes ago. But when I tried to create the release binary I got a bunch of errors when attempting build and run. They all stemmed from these two errors FBConnect/FBConnect.h: No such file or directory. FBConnect/FBSession.h: No such file or directory. In Xcode in the Groups and files window I have the following structure AppName FBConnect Classes Other Sources Resources etc. And FBConnect.h and FBSession.h are present in FBConnect. As I say this all works fine in debug mode but it isn't recognising the files in release mode. Does anyone know how to remedy this? Thanks in Advance.
