BOOL success = NO;

//  This requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

CkoHttp *http = [[CkoHttp alloc] init];

//  If SharePoint Windows classic authentication is used, then set the 
//  Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = @"SHAREPOINT_USERNAME";
http.Password = @"SHAREPOINT_PASSWORD";
http.LoginDomain = @"SHAREPOINT_NTLM_DOMAIN";
http.NtlmAuth = YES;

//  The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
//  If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
//  establish the cookie as shown at SharePoint Online Authentication

//  This example will delete the file named "penguins2.jpg" 
//  which is located in the "/Documents" folder.

CkoHttpRequest *req = [[CkoHttpRequest alloc] init];

//  See this example for details on
//  how to get (and cache) a form digest value

//  Add additional required headers.
[req AddHeader: @"IF-MATCH" value: @"*"];
[req AddHeader: @"X-HTTP-Method" value: @"DELETE"];

//  Send the POST using https (TLS). Port 443 is the default port for https.

    NSLog(@"%@",[xml GetXml]);

    //  For example, if the file did not exist, this would be the XML response:
    //  <?xml version="1.0" encoding="utf-8" ?>
    //  <m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
