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

// The mailman object is used for sending and receiving email.
CkoMailMan *mailman = [[CkoMailMan alloc] init];

// Set the SMTP server.
mailman.SmtpHost = @"smtp.chilkatsoft.com";

// Set the SMTP login/password (if required)
mailman.SmtpUsername = @"myUsername";
mailman.SmtpPassword = @"myPassword";

// Create a new email object
CkoEmail *email = [[CkoEmail alloc] init];

email.Subject = @"This is a vcard test";
email.Body = @"This is a vcard test";
email.From = @"Chilkat Admin <admin@chilkatsoft.com>";
BOOL success = [email AddTo: @"Chilkat Support" emailAddress: @"support@chilkatsoft.com"];
// To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

// A vCard is an email attachment having a Content-Type = "text/x-vcard".
// Call AddStringAttachment to add a vcard from an in-memory string.
// The filename should have a ".vcf" file extension.  Chilkat will automatically
// recognize it and set the content-type to "text/x-vcard";

// Your application is responsible for providing the vcard formatted string.  For example:
// See http://en.wikipedia.org/wiki/VCard
// 
// begin:vcard
// fn:Matt Smith
// n:Smith;Matt
// org:Chilkat Software, Inc.
// tel;work:630-784-9670
// url:http://www.chilkatsoft.com
// version:2.1
// end:vcard

NSString *vcard = @"begin:vcard ...";
success = [email AddStringAttachment: @"admin.vcf" str: vcard];
if (success != YES) {
    NSLog(@"%@",email.LastErrorText);
    return;
}

// Call SendEmail to connect to the SMTP server and send.
// The connection (i.e. session) to the SMTP server remains
// open so that subsequent SendEmail calls may use the
// same connection.  
success = [mailman SendEmail: email];
if (success != YES) {
    NSLog(@"%@",mailman.LastErrorText);
    return;
}

// Some SMTP servers do not actually send the email until 
// the connection is closed.  In these cases, it is necessary to
// call CloseSmtpConnection for the mail to be  sent.  
// Most SMTP servers send the email immediately, and it is 
// not required to close the connection.  We'll close it here
// for the example:
success = [mailman CloseSmtpConnection];
if (success != YES) {
    NSLog(@"%@",@"Connection to SMTP server not closed cleanly.");
}

NSLog(@"%@",@"Mail with vCard Sent!");
