CkoEmail *email = [[CkoEmail alloc] init];

// The FindIssuer method is deprecated:

CkoCert *certObj = [email FindIssuer: cert];
if (email.LastMethodSuccess == NO) {
    NSLog(@"%@",email.LastErrorText);
    return;
}

// ...

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

BOOL success = [cert GetIssuer: issuerCert];
if (success == NO) {
