iOS Points

Description

Simple extension for iOS to convert points into pixels and vice versa.

To understand what points are, I suggest reading this article: http://blog.fluidui.com/designing-for-mobile-101-pixels-points-and-resolutions/

TL;DR:

• On the iPhone, 1 point is equal to 1 pixel when the resolution is 163DPI. This was the case for all the iPhones before the Retina era.
• At 326DPI, like the iPhone 4, 5 and 6, 1 point is equal to 2 pixels across and 2 pixels down, or 4 total pixels. Meaning your 100x100 image will render a quarter the size on a retina device if rendered by counting pixels alone.
• At 401DPI like the iPhone 6+, 1 point is equal to 3 pixels across and 3 pixels down, or 9 total pixels.

I made this extension because some of my extensions for iOS take or return values in points, and it's annoying to have to detect the device type to convert from/to pixels.
