Question

I have appended the IV to the AES Encryption/decryption code by using objective c in iOS and able to decrypt and encrypt the same. Right now I am trying to add the salt to t

Answer 1

You're stretching your encryption key, but you're not stretching your decryption key. The decryption code never calls AESKeyForPassword, and I don't see anywhere that you store the salt to send it to the decryptor (the way you send the IV to the decryptor). You can't just apply PBKDF2 to one side. That gives you completely different keys.
