CkoCert *cert = [[CkoCert alloc] init];

// ------------------------------------------------------------------------
// The GetCertChain method is deprecated:

CkoCertChain *certchainObj = [cert GetCertChain];
if (cert.LastMethodSuccess == NO) {
    NSLog(@"%@",cert.LastErrorText);
    return;
}

// ...

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

CkoCertChain *certchainOut = [[CkoCertChain alloc] init];
BOOL success = [cert BuildCertChain: certchainOut];
if (success == NO) {
    NSLog(@"%@",cert.LastErrorText);
