I am using plist to parse dozens of data into tableview. It works pretty fine. Yet, it is unprotected. Someone can easily reach that plist file if he opens the content of .ipa file. I want to protect my data. Is there anyway to protect .plist file? As far as I know, Sqlite protects data by changing values into complex keys. Yet, if I am to use sqlite for my app, I have to change the way how I parse data into strings. I know nothing about SQLite.
Where to start? What do you suggest? Is there easier and better way of protecting data in ios apps?
Thanks in advance.
Example of my plist:
<?xml version="1.0" encoding="UTF-8"?>

If all you want is to encrypt your plist files then have a look at this SO question.
If you really want sqlite, then instead of dealing with sqlite directly, have a look at CoreData. Core data is an Apple framework which makes it very easy to store and fetch data using NSObjects and relationships. Core data can use sqlite for storage if you want. There’s a fairly steep learning curve but it’s worth learning since it’s a very useful framework to master.
Keep in mind the sqlite DB is just stored in a file which anyone can read by default. So you’ll need a little more effort to encrypt it.
