Question

I want to send param’s in XML format to a web service from Objective C app without getting an response (I don’t need to handle with it). What is the best and fast way doing that?

Let’s say I have the next XML:

NSString *xmlParams=[NSString stringWithFormat:@"<?xml version=\"1.0\" encoding=\"utf-8\"?><R><Root><Grade>33</grade></Root></R>"];

And the address where to send the XML is : http://www.myServer.com\service.asmx

What is the implemention for sending xmlParams to that address?

I just answered a similar question, so I’ll just copy and paste some of that code here:

- (void)myFunctionToSendDataToTheServer
{

    MKNetworkEngine *engine = [[MKNetworkEngine alloc] initWithHostName:@"myServer.com"];

    MKNetworkOperation *op = [engine operationWithPath:@"/service.asmx"];

    op.postDataEncoding = MKNKPostDataEncodingTypeCustom;

    [op setCustomPostDataEncodingHandler:^NSString *(NSDictionary *postDataDict) {
        return [NSString stringWithFormat:@"<R><Root><Grade>33</grade></Root></R>"];
    } forType:@"application/xml"];

    [engine enqueueOperation:op];
}

I would suggest adding a third party library to handle the network code. In this case I used MKNetworkKit.

The line of code that says “[engine enqueueOperation:op];” is the part that sends the request off to the server.
If you change you mind and do want or need to handle a response then add something like this before the “[engine enqueueOperation:op];”:

[op onCompletion:^(MKNetworkOperation *completedOperation) {

        NSLog(@"Successful response from server: %@", [completedOperation responseString]);

    } onError:^(NSError *error) {

        NSLog(@"Error from server; %@", [error debugDescription]);
    }];
