Answer 1

You are correctly assigning your soap request in NSString. Now you have to create NSMutableURLRequest object and send the request as follow
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:webServiceUrl];
NSString *msgLength = [NSString stringWithFormat:#"%d", [soapMessage length]];
[req addValue:#"text/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[req addValue:yourSoapAction forHTTPHeaderField:#"SOAPAction"];
[req addValue: msgLength forHTTPHeaderField:#"Content-Length"];
[req setHTTPMethod:#"POST"];
[req setHTTPBody:[soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSHTTPURLResponse* urlResponse = nil;
NSError *error = [[[NSError alloc] init] autorelease];
NSData *webData = [NSURLConnection sendSynchronousRequest:req returningResponse:&urlResponse error:&error];
Now parse your webData using any of xml parser. I generally prefer NSXMLParser
Hope this helped..

try with following sample code;
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"
"<getLogin xmlns=\"http://schemas.xmlsoap.org/soap/encoding/\">\n"
"<email>%#</email>\n"
"<user_pwd>%#</user_pwd>\n"
"</getLogin>\n"
"</soap:Body>\n"
"</soap:Envelope>\n", userNameField.text,passWordField.text];
NSLog(#"%#", soapMessage);
NSURL *url = [NSURL URLWithString:#"web service url"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
NSString *msgLength = [NSString stringWithFormat:#"%d", [soapMessage length]];
[theRequest addValue: #"text/xml; charset=utf-8" forHTTPHeaderField:#"Content-Type"];
[theRequest addValue: #"your soap action" forHTTPHeaderField:#"SOAPAction"];
[theRequest addValue: msgLength forHTTPHeaderField:#"Content-Length"];
[theRequest setHTTPMethod:#"POST"];
[theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
if( theConnection ){
webData = [[NSMutableData data] retain];
}else{
NSLog(#"theConnection is NULL");
}
