问题
In Xcode 4, order to commit the entire project(all source files) to the source control repo, does one have to select all the files in the project navigator(Cmd-A) or is is it sufficient if I select just the Project file at the top and then File->SourceControl->Commit?
回答1:
If you choose File > Source Control > Commit... (or press Command-Option-C), Xcode will list all changed files in the commit window.
If you right-click or control-click on a file and choose Source Control > Commit Selected Files..., Xcode will only list the files that were selected in the project navigator and have changes.
