See this example may be it will help you:-

NSString *bURL = @"";
NSString *path = @"method/url/";

NSMutableDictionary *param = [NSMutableDictionary dictionary];
[parameters setObject:@"yourDictValue" forKey:@"YourDictkey"];

AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:bURL];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
manager.responseSerializer = [AFJSONResponseSerializer serializer];

[manager POST:path parameters:param success:^(NSURLSessionDataTask *task, id responseObject) {

        NSLog(@"JSON: %@", responseObject);
        //here is place for code executed in success case

} failure:^(NSURLSessionDataTask *task, NSError *error) {

  UIAlertView *alertV = [[UIAlertView alloc] initWithTitle:@"Error while sending POST"
                                                            message:@"Sorry, try again."
        [alertV show];

        NSLog(@"Err: %@", [error localizedDescription]);
