BOOL success = NO;

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

CkoImap *imap = [[CkoImap alloc] init];

// Connect to the iCloud IMAP Mail Server
imap.Ssl = YES;
imap.Port = [NSNumber numberWithInt:993];
success = [imap Connect: @"imap.mail.me.com"];
if (success == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

// The username is usually the name part of your iCloud email address 
// (for example, emilyparker, not emilyparker@icloud.com).
success = [imap Login: @"ICLOUD_USERNAME" password: @"ICLOUD_PASSWORD"];
if (success == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

// Select an IMAP folder/mailbox
success = [imap SelectMailbox: @"Inbox"];
if (success == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;
}

// Once the folder/mailbox is selected, the NumMessages property
// will contain the number of emails in the mailbox.
// Loop from 1 to NumMessages to fetch each email by sequence number.

CkoEmail *email = [[CkoEmail alloc] init];
int i;
int n = [imap.NumMessages intValue];
BOOL bUid = NO;
for (i = 1; i <= n; i++) {

    // Download the email by sequence number.
    success = [imap FetchEmail: NO msgId: i bUid: bUid email: email];
    if (success == NO) {
        NSLog(@"%@",imap.LastErrorText);
        return;
    }

    NSLog(@"%d%@%@",i,@": ",email.From);
    NSLog(@"%@%@",@"    ",email.Subject);
    NSLog(@"%@",@"-");
}

// Disconnect from the IMAP server.
success = [imap Disconnect];

NSLog(@"%@",@"Success.");

// Sample output:

// 	1: iCloud <noreply@email.apple.com>
// 	    Welcome to iCloud Mail.
// 	-
// 	2: "Chilkat Software" <support@chilkatsoft.com>
// 	    This is a test

// 	Success.
