Easily get+set CALayer background and border colors as UIColors in an ARC-safe fashion.

Lets you write:

view.layer.jr_backgroundUIColor = [UIColor colorWithRed:0.2 green:0.3 blue:0.4 alpha:1.0];

Instead of having to write:

UIColor *color = [UIColor colorWithRed:0.2 green:0.3 blue:0.4 alpha:1.0];
view.layer.backgroundColor = color.CGColor;
