Of course, the first step in any search should be to read Apple's documentation , but many people seem not to want to read the whole thing. Trust me, folks, it is worth it. But Apple's documentation on creating delegates doesn't use protocols, which are such an amazing and useful part of the Objective-C language.

ASIHTTPRequest is an easy to use wrapper around the CFNetwork API that makes some of the more tedious aspects of communicating with web servers easier. It is written in Objective-C and works in both Mac OS X and iPhone applications. It is suitable performing basic HTTP requests and interacting with REST-based services (GET / POST / PUT / DELETE). The included ASIFormDataRequest subclass makes it easy to submit POST data and files using multipart/form-data. http://allseeing-i.com/ASIHTTPRequest/
