    nsstring *username = @"username";     nsstring *password = @"pasword";     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:header>\n"                              "<requestauthenticator xmlns=\"http://tempuri.org/\">\n"                              "<password>%@</password>\n"                              "<username>%@</username>\n"                              "</requestauthenticator>\n"                              "</soap:header>\n"                              "<soap:body>\n"                              "<methodname xmlns=\"http://tempuri.org/\"/>\n"                              "</soap:body>\n</soap:envelope>\n",password,username];     nslog(@"%@",soapmessage);       nsurl *url = [nsurl urlwithstring:@"http://websitename.com/website_english/wservice/website_service.asmx"];     nsmutableurlrequest *request = [nsmutableurlrequest requestwithurl:url];     /*asihttprequest *request = [asihttprequest requestwithurl:url];     [request setusekeychainpersistence:yes];     [request setusername:@"username"];     [request setpassword:@"password"];     [request setdelegate:self];     [request startasynchronous];*/     nsstring *msglength = [nsstring stringwithformat:@"%d", [soapmessage length]];      [request addvalue: @"text/xml; charset=utf-8" forhttpheaderfield:@"content-type"];     [request addvalue: @"http://tempuri.org/methodname" forhttpheaderfield:@"soapaction"];     [request addvalue: msglength forhttpheaderfield:@"content-length"];     [request sethttpmethod:@"post"];     [request sethttpbody: [soapmessage datausingencoding:nsutf8stringencoding]];      nsurlconnection *theconnection = [[nsurlconnection alloc] initwithrequest:request delegate:self];      if( theconnection )     {         webdata = [[nsmutabledata data] retain];     }     else     {         nslog(@"theconnection null");     }  -(void)connection:(nsurlconnection *)connection didreceiveresponse:(nsurlresponse *)response {     [webdata setlength: 0]; } -(void)connection:(nsurlconnection *)connection didreceivedata:(nsdata *)data {     [webdata appenddata:data]; } -(void)connection:(nsurlconnection *)connection didfailwitherror:(nserror *)error {     nslog(@"error theconenction");     [connection release];     [webdata release]; } -(void)connectiondidfinishloading:(nsurlconnection *)connection {     nslog(@"done. received bytes: %d", [webdata length]);     nsstring *thexml = [[nsstring alloc] initwithbytes: [webdata mutablebytes] length:[webdata length] encoding:nsutf8stringencoding];     nslog(@"%@",thexml);     [thexml release]; } 

but returning me 0 bytes , no xml, original website name not disclose security.

i tried hellosoap.xcodeproj sample code aswell unable through it.

if problem because of authentication take @ question , answer had deal there: soap , xml response parsing samples iphone/ipad?

other without knowing more service expects , passing, don't know how you'll able get. now, don't see wrong code have.

edit:

- (void)connection:(nsurlconnection *)connection didreceiveauthenticationchallenge:(nsurlauthenticationchallenge *)challenge {     nsurlcredential *mycreds = [[nsurlcredential alloc] initwithuser:@"**username**" password:@"**password**" persistence:no];      [challenge.sender usecredential:mycreds forauthenticationchallenge:challenge];     [mycreds release]; } 

i edited in code answer linked question ease of access.

also, i'm re-reading code, username , password actually, "username" , "password"? if so, , copy , pasted above code, when set variable password near top, have misspelled "password".
