Accessing web services in iPhone using SOAP without method names?

I am trying to access a webservice from my server using this tutorial con开发者_如何学Csume web services.. i have been successful in accessing the web service and retrieving a string from it. but in most of the tutorials i have come across we need to give the method names in the web service thru the SOAP actions.. Is there any way in which we can even retrieve the methods that are present in the web service first within our application and then access it using those methods,, so the web service will be more flexible then and we can add more methods later??

You can use WSDL from service and generate proxy. WSDL contains service methods list. Check this

The first thing that springs to mind is to hit the WSDL definition, and search through it for the messages and data types you want.
