Thanks for reading. You're right I guess. But although all web services involve a POST (or a GET) not all GETs or POSTs are for web services. So perhaps I should rephrase my question to a more specific:
Does the iphone SDK provide an API for SOAP based web services, or at the very least, for doing basic POSTs and GETs?
Yes, but you have to do a lot of work yourself. If Apple chose to provide a set of classes for this sort of thing you can imagine it would be a few lines of code only.
