}

please help.thank.

i've worked requesting soap url before, next code worked 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 null"); }
