Using AFNetworking 3 0  you should write  NSString  strURL     quot https   exampleWeb com webserviceOBJ quot   NSURL   urlStr    NSURL URLWithString strURL    NSDictionary  dictParameters       quot user height  quot   height   quot user weight  quot   weight    AFHTTPSessionManager   manager    AFHTTPSessionManager manager      manager POST url absoluteString parameters dictParameters success   NSURLSessionTask  task  id responseObject        NSLog   quot PLIST     quot   responseObject         failure   NSURLSessionTask  operation  NSError  error        NSLog   quot Error     quot   error

It s first worth adding  as this answer is still popular 6 years after I initially wrote it     that the first thing you should consider is whether you should even use AFNetworking  NSURLSession was added in iOS 7 and means you don t need to use AFNetworking in many cases - and one less third party library is always a good thing   For AFNetworking 3 0   AFHTTPSessionManager  manager    AFHTTPSessionManager manager   NSDictionary  params       user height    height                             user weight    weight    manager POST   https   example com myobject  parameters params progress nil success   NSURLSessionTask  task  id responseObject        NSLog   JSON       responseObject     failure   NSURLSessionTask  operation  NSError  error        NSLog   Error       error         For AFNetworking 2 0  and also using the new NSDictionary syntax    AFHTTPRequestOperationManager  manager    AFHTTPRequestOperationManager manager   NSDictionary  params       user height    height                             user weight    weight    manager POST   https   example com myobject  parameters params success   AFHTTPRequestOperation  operation  id responseObject        NSLog   JSON       responseObject     failure   AFHTTPRequestOperation  operation  NSError  error        NSLog   Error       error         If you are stuck using AFNetworking 1 0  you need to do it this way   NSURL  url    NSURL URLWithString   https   example com     AFHTTPClient  httpClient     AFHTTPClient alloc  initWithBaseURL url    NSDictionary  params    NSDictionary dictionaryWithObjectsAndKeys                          height    user height                            weight    user weight                            nil    httpClient postPath    myobject  parameters params success   AFHTTPRequestOperation  operation  id responseObject        NSString  responseStr     NSString alloc  initWithData responseObject encoding NSUTF8StringEncoding       NSLog   Request Successful  response        responseStr     failure   AFHTTPRequestOperation  operation  NSError  error        NSLog    HTTPClient Error        error localizedDescription
