Xcode 4.5.2 svn 无法update

You can get that to show up under File-->Source Control and holding down the control key.

It looks like in XCode 4.4. the default source control options have been switched around as follows:

Xcode 4.4+ - default = "Update"

"Update" (Cmd+Opt+X) - Silently updates all files unless there is a merge conflict that needs to be manually corrected

"Update..." (Ctrl+Cmd+Opt+X) - Updates all files allowing you to verify/merge updated files

Xcode 4.3 - default = "Update..."

"Update..." (Ctrl+Cmd+Opt+X) - Updates all files allowing you to verify/merge updated files

"Update All" (Cmd+Opt+X) - Silently updates all files unless there is a merge conflict that needs to be manually corrected
