I've worked with requesting a soap URL before, the following code worked for me:
NSString *soapMessage = [NSString stringWithFormat:
#"<?xml version=\"1.0\" encoding=\"utf-8\"?>\n"
"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n"
"<soap:Body>\n"
"<YourServiceName xmlns=\"http://tempuri.org/\">\n"
"<username>%#</username>\n"
"<passowrd>%#</passowrd>\n"
"</YourServiceName>\n"
"</soap:Body>\n"
"</soap:Envelope>\n", userName, passWord
];
NSURL *url = [NSURL URLWithString:#"http://URL/service1.asmx"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:#"%d", [soapMessage length]];
[theRequest addValue: #"text/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[theRequest addValue: [NSString stringWithFormat:#"http://tempuri.org/%#",service] forHTTPHeaderField:#"SOAPAction"];
[theRequest addValue: msgLength forHTTPHeaderField:#"Content-Length"];
[theRequest setHTTPMethod:#"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
[theRequest setTimeoutInterval:10];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if( theConnection )
{
responseData = [[NSMutableData data] retain];
}
else
{
NSLog(#"theConnection is NULL");
}
