Configure Network Proxy Settings in Xcode for SVN Connection

I tried to configure the SVN repository in my Xcode 3 and Xcode 4 but in both versions i am getting the error that "Options are missing:" and at the same time i tried to checkout the code from my svn through command line with the help of SVN with proper network proxy commands it is working.I used the below command:

svn --config-option servers:global:http-proxy-host=proxy_url --config-option servers:global:http-proxy-port=port_no checko开发者_开发技巧ut https://repository_url foldername

My question is how to achieve the same thing using the xcode?

Do you use in Xcode an URL like "svn+ssh://yourName@repo.yourRepositoryUrl…"?
