objective-c: Webservice, How to tell about specific method to access

I am trying to access http://services-staging.cmtnyc.com/payment/payment.asmx web service and

AuthorizeCreditTrip I checked this webservice on .Net application and its working fine but in objective-c it does not responds with the same data.

The web service exposes 5 methods and I want to access 4th. But I think this code do not specify that which methood to access . forHTTPHeaderField:@"SOAPAction" tells but I do not think that its correct link to put here.

Does not responds means it sends nothing in response.

I think that I am unable to set valid SOAPAction

I've used the below code and has worked fine for me:

    NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];

    NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMsg length]];
    [req addValue:@"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [req addValue:@"http://tempuri.org/SearchCustomer" forHTTPHeaderField:@"SOAPAction"];
    [req addValue:msgLength forHTTPHeaderField:@"Content-Length"];

    [req setHTTPMethod:@"POST"];
    [req setHTTPBody: [soapMsg dataUsingEncoding:NSUTF8StringEncoding]];

where url is my Url, soapMsg is my soap message and @"http://tempuri.org/Method" is the soap action.

Here is how I have it working:

NSURL *urlWS = [NSURL URLWithString:kUrlServer];
NSMutableURLRequest *theRequest;
theRequest = [NSMutableURLRequest requestWithURL:urlWS];

NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]];
[theRequest addValue: @"application/soap+xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPMethod:@"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];

Perhaps you are missing application/soap+xml.
