How to prevent images from being copied from an iPhone/iPad app

My App will require the use of about 500 images and this number could possibly grow. Those images are read-only and the user won't add any pictures while using the app.

Image sizes will probably range between 50 to 250k .

I want to prevent the images from being copied by someone exploring the bundle resources for example.

So far I am thinking of putting all the images in a SQLite database and then encrypt it using SQLCipher for example.

Does this seems a bit over the top ?

In your opinion what would be the best solution ?

Could Apple reject it ?

I understand that people can always take screenshots, etc... but I just want to make it difficult without it being a nightmare to code and use.

Cheers, Duz

You may consider cropping your images into smaller tiles and regrouping them into a bigger image when it's time to display.

In addition to the benefit of prohibiting a direct copy, it also improve performance for big images.

Refer to the Apple ScrollViewSuite sample for implementation details.
