How to use a web service in Objective-C?

Question

I have a web service developed in ColdFusion that I am trying to use on an iPhone. The web service returns JSON, which should be easy enough to read.

However, I could not find a good simple example of an iPhone application that calls a web service and uses data. Are there any good tutorials or examples that I just skipped?
