hmacsha1

hi all, i want to generate HMAC-SHA1 of NSString type variable. I see the post but this method give me error in CCHmac(kCCHmacAlgSHA256, cKey, strlen(cKey), cData, strlen(cData), cHMAC);

and

NSString *hash = [HMAC base64Encoding]; line.

Please suggest how can I generate the HMAC-SHA1 of any string.
