以下命令在 OSX Terminal 测试通过
nickx:~/Documents $ svn --version
svn, version 1.6.5 (r38866)
compiled Jun 24 2010, 17:16:45
nickx:~/Documents $ svn ps svn:ignore '
*.pbxuser
*.mode1v3
' yourproject.xcodeproj
nickx:~/Documents $ svn ps svn:externals "LlamaSettings http://llamasettings.googlecode.com/svn/trunk/src/LlamaSettings" .
(注意最后的点，表示在当前目录设置 externals property)
