sqlite: Sqlcipher iOS always saying "Password correct"

I have a problem using sqlcipher for ios. I have followed this example to create database named "testing.db" :

The problem is when I test my code with different password (keys), it always displays to me "Password is correct, or a new database has been initialized" even if I set a wrong filename for my database (always same message).
