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

// The FetchSingle method is deprecated:

CkoEmail *emailObj = [imap FetchSingle: 1 bUid: NO];
if (imap.LastMethodSuccess == NO) {
    NSLog(@"%@",imap.LastErrorText);
    return;

// Do the equivalent using FetchEmail.
// Your application creates a new, empty Email object which is passed 
// in the last argument and filled upon success.
