How to consume ASPX webservices in iOS?

Could anybody clarify the process of consuming aspx webservices in iOS? I have already tried JSON framework but now, need to create an app that consumes .net webservices in XML format. I need both to post some data to, and get data from the server. I already read about existing XML parsers for iOS that I found (here)

The question is do I need to do additional setup, like wrapping my query strings in SOAP or smth, in order to communicate with webserver? Would it be sufficient to use only one of mentioned libraries in the link or do I need additional stuff?

UPDATE: I found one tutorial on web (here) that demonstrates how to consume web services using Json-framework. Also, I found another one that demonstrates it using NSXMLParser (here). I'm not not very familiar with WSDL and SOAP, so any detailed explanation on how to implement would be desirable :). In both of these examples you just have to construct a request string in xml format and execute it, and that's it. Both examples actually bypasses the heavyness of SOAP and WSDL, so I was wondering do I have to know and do more that just construct a request string, execute it and get response?

While wsdl2objc is out there (as noted by @Girish Kolari), the truth is that there's no easy answer. I've never successfully gotten wsdl2objc working well for something that I couldn't have done more easily by hand. You will need to learn SOAP and WSDL. That's just a fact of life if you can't get access to a REST interface. In my experience, your best bet for simple SOAP access is to do it by hand, and your best bet for somewhat complicated SOAP access is gSOAP. Your best bet for very complicated access is to redesign something so it's not so complicated, ideally in REST. SOAP is a giant pain that some languages (C#) shield you from. ObjC does not shield you from it, so it continues to be a giant pain.

Yes, SOAP leaves a bad taste in my mouth.
