How to load xml through http proxy objective c?

I developing very basic program for mac.开发者_开发技巧 The program read xml file using NSXMLParser with NSURLConnection. I need to load URL using http proxy server (not system proxy). Is anyone knows how to do it? Thanks.

If you check out the docs for NSURLConnection, they will tell you that you need to implement the callback methods in the NSURLConnectionDelegate protocol, and will give you details.

That page also points to several examples, with sample code.

You can also check out the URL Loading System Programming Guide at developer.apple.com, which will give you additional information on how these classes can be used.
