google到的教程针对旧版Xcode的，和Xcode5有些不一样。 Add Remote后，push会提示: To git#github.com:vincent1q84/NewOne

! [rejected] master -> master (fetch first)

error: failed to push some refs to 'git#github.com:vincent1q84/NewOne'

hint: Updates were rejected because the remote contains work that you do

hint: not have locally. This is usually caused by another repository pushing

hint: to the same ref. You may want to first merge the remote changes (e.g.,

hint: 'git pull') before pushing again.

hint: See the 'Note about fast-forwards' in 'git push --help' for details.

求解啊。
