How do you zip a Xcode project?

Hey,

I have tried to send my friend some code(开发者_如何学编程project), and well I zipped the folder which was created when i started the project.

But there are files missing.

Any idea how i can grab all the files easily ?

Are you sure that all the files referenced from the project are inside the project directory? (When you add an existing file to a project you are asked whether to copy it or not, maybe you did not)
