How to adjust a view's height with Auto Layout when a keyboard appears or disappears in iOS 7.

This gist outlines how to resize a view when a keyboard appears using Auto Layout (there are a bunch of code samples out there that manually adjust the view's frame, but that's just so 2013). The method I outline below works universally on both iPhone and iPad, portrait and landscape, and is pretty darn simple.

Setting Up

The first thing to do is to define our containing view controller, the view, and the bottom constraint that we'll use to adjust its size.

Here's HeightAdjustingViewController.h. We don't need to expose any public properties, so it's pretty bare.

Combining a strong colour with a blurred and translucent UINavigationBar in iOS 7.
// cheers to @stroughtonsmith for helping out with this one
UIColor *barColour = [UIColor colorWithRed:0.13f green:0.14f blue:0.15f alpha:1.00f];
UIView *colourView = [[UIView alloc] initWithFrame:CGRectMake(0.f, -20.f, 320.f, 64.f)];
colourView.opaque = NO;
colourView.alpha = .7f;
colourView.backgroundColor = barColour;
self.navigationBar.barTintColor = barColour;
