NSURLCache Testharness

Is NSURLCache broken in iOS8.1 ?

I created this simple test project to show that my NSURLCache does not work as I would expect. Take a look and let me know what I did wrong! The ever so slightest hint is very welcome! Thanks!

The App Interface

• Top section hosts six UIImageView instances.
• Middle section shows information about the current state of our NSURLCache instance.
• The table view shows the logs broken out on a per-request-level.
