Can resources be extracted from a compiled iPhone app? If yes, how can they be secured?

Question

Can resources be extracted from a compiled iPhone app that is released to the iTunes store? I'm particularly interested in the security of XML files... if I have copyrighted data in an XML document in my resource directory, how likely is it for someone to extract that information and paste it around the internet?

If it's as easy as using a resource editor, how can that data be secured?

Answer 1

You can encrypt/decrypt the data on write/read.

Take a look at CommonCrypto class.

Answer 2

Yes, resources can definitely be extracted. See this question

If it's important to you, encrypting the data is a good idea, as medopal said.
