Try this code:- 

   KeychainItemWrapper *keychain = [[KeychainItemWrapper alloc] initWithIdentifier:@"TestAppLoginData" accessGroup:nil];
                        [keychain setObject:(__bridge id)(kSecAttrAccessibleWhenUnlocked) forKey:(__bridge id)(kSecAttrAccessible)];
                        // Store username to keychain
                        [keychain setObject:emailTxtFld.text forKey:(__bridge id)kSecAttrAccount];
                        // Store password to keychain
                        [keychain setObject:passwordTxtFld.text forKey:(__bridge id)kSecValueData];

and download the KeychainItemWrapper file from tutorial by apple

  • this code will store username and password for one user.If an other user want to store his username and password then again this code will run.Then object value will be different but the key will be same again for eg. kSecAttrAccount will be the key for all username.Will it be ok to use same key. – Parth Grover Sep 09 '13 at 09:54
