AFNetworking POST to REST webservice

Answer 1

Use AFHTTPClient -postPath:parameters:success:failure:, passing your parameters (nested dictionaries/arrays are fine). If you're expecting a plist back, be sure to have the client register AFPropertyListRequestOperation.

In any case, setValue:forHTTPHeaderField: is not what you want here. HTTP headers are for specifying information about the request itself; data is part of the request body. AFHTTPClient automatically converts parameters into either a query string for GET requests or an HTTP body for POST, et al.
