Question

in my Iphone app i use AFNetworking to POST some data to a webservice and get some data back…

Here is my example, i always get “false” back as response, what i am doing wrong?

NSURL *baseURL = [NSURL URLWithString:@"http://myPath/Iphone/method"];


    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:baseURL];
    [httpClient defaultValueForHeader:@"Accept"];

    NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                            [udid copy], @"uuid",
                            nil];


    NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"http://myPath/Iphone/method" parameters:params];


    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];


    [httpClient registerHTTPOperationClass:[AFXMLRequestOperation class]];


    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
        response = [operation responseString];
        NSLog(@"response: %@",response);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"error: %@", [operation error]);
    }];


    [operation start];

EDIT: the method i call in the Url returns a string (no the string is not false)

---

  [HttpPost]
        public bool checkIphone(string uuid)
        {
           IDictionary<string,object> check  = Request.Properties;

           uuid = check["uuid"].ToString();

           //do anything with the uuid

           if (1<0)
           {
               return true;
           }
           else
           {
               return false;
           }

        }

this method i am calling with my iphone and normaly it should return xml or?

You are using a complicated way of building the operation, but it will work.
But it should work, the thing you are missing is assign the XMLparser.
In the documentation of AFXMLRequestOperation is stated.

 NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST" path:@"http://myPath/Iphone/method" parameters:params];

AFXMLRequestOperation *operation = [[AFXMLRequestOperation alloc] initWithRequest:request];
operation.responseXMLParser = xmlParser; //Here you should assign an instance of NSXMLParser to handle you XML parsing.

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    response = [operation responseString];
    NSLog(@"response: %@",response);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"error: %@", [operation error]);
}];

Also there is not need to make the NSURLRequest via the AFHTTPClient, you can easily create one you self or use the AFHTTPClient to do the creation of the AFHTTPRequestOperation for you.

To use the AFHTTPClient to just return whatever the server returns :

// Don't include the method here
NSURL *baseURL = [NSURL URLWithString:@"http://myPath/Iphone/"];

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:baseURL];
[httpClient defaultValueForHeader:@"Accept"];

NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:
                        [udid copy], @"uuid",
                        nil];

[httpClient postPath:@"method" parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) {
    // reponseObject will hold the data returned by the server.

}failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error retrieving data: %@", error);
}];
