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.

Communicate between objects using channels

When you have two objects A and B, say two view controllers, that you want to have talk to each other, you can choose from the following options:

• NSNotificationCenter. This is anonymous one-to-many communication. Object A posts a notification to the NSNotificationCenter, which then distributes it to any other objects listening for that notification, including Object B. A and B do not have to know anything about each other, so this is a very loose coupling. Maybe a little too loose...

• KVO (Key-Value Observing). One object observes the properties of another. This is a very tight coupling, because Object B is now peeking directly into Object A. The advantage of KVO is that Object A doesn't have to be aware of this at all, and therefore does not need to send out any notifications -- the KVO mechanism takes care of this behind the scenes.

• Direct pointers. Object A has a pointer to Object B and directly sends it messages when something of interest h
