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

// The mailman object is used for receiving (POP3) 
// and sending (SMTP) email.
CkoMailMan *mailman = [[CkoMailMan alloc] init];

// Set the POP3 server's hostname
mailman.MailHost = @"pop3.example.com";

// Set the POP3 login/password.
mailman.PopUsername = @"pop3_login";
mailman.PopPassword = @"pop3_password";
mailman.MailPort = [NSNumber numberWithInt:995];
mailman.PopSsl = YES;

// You may explicitly begin and end POP3 sessions by calling
// Pop3BeginSession and Pop3EndSession.  However, 
// if a method is called that requires a connection to the POP3
// server, the connection and session will become established
// automatically.  Therefore, it is not required to explicitly call
// Pop3BeginSession and Pop3EndSession.  

BOOL success = [mailman Pop3BeginSession];
if (success != YES) {
    NSLog(@"%@",mailman.LastErrorText);
    return;
}

// Get a list of the UIDLs for the email in the mailbox and print it.
CkoStringArray *sa = [mailman GetUidls];

int n = [sa.Count intValue];
while (i < n) {
    NSLog(@"%@",[sa GetString: [NSNumber numberWithInt: i]]);
    i = i + 1;
