/**
 * VH and VW units can cause issues on iOS devices: http://caniuse.com/#feat=viewport-units
 * 
 * To overcome this, create media queries that target the width, height, and orientation of iOS devices. 
 * It isn't optimal, but there is really no other way to solve the problem. In this example, I am fixing 
 * the height of element `.foo` —which is a full width and height cover image.

If you've haven't seen it before, there is a cool accessibility feature in UITableView that allows the user to toggle between different actions. It's really very elegant and it's a powerful and convenient implementation for VoiceOver users on iOS. One could say that it's the VoiceOver version of the swipe-to-delete feature.

To try it out yourselves, open one of the built in apps like Mail or Notes and turn on VoiceOver. If you are afraid to accidentally delete some of your important notes or email, you can also create a new Master-Detail Application in Xcode and run it on your device. Navigate to one of the cells and use the "Rotor" (rotate with two fingers on the screen) to find the "Actions" item. Now you can swipe up and down do toggle between "Activate Item (default action)" and "Delete". If you now double tap, the cell gets deleted instead of selected.

This is the default behavior and you get this accessibility out of the box with UITableView.
