I have recently downloaded GitHub
and created a repository on it. I am trying to upload an Objective C
project in it. How do I go about doing this?
Well, there really is a lot to this. I'm assuming you have an account on http://github.com/. If not, go get one.
After that, you really can just follow their guide, its very simple and easy and the explanation is much more clear than mine: http://help.github.com/ >> http://help.github.com/mac-set-up-git/
To answer your specific question: You upload files to github through the git push
command after you have added your files you needed through git add 'files'
and commmited them git commit -m "my commit messsage"
