title: Adding an animated, modal popup view
body: <p>I'd like to create a view that appears scrolling in from the bottom (on iPad) and sits centered, modally over the currently open view, something like this ...</p>

  <p>What would be the straightforward (and recommended) way to do this when developing apps for iOS7 and up? Is it a matter of simply instantiating the view controller class and adding it as a child or are there any better methods to do this, that include automatically managed modality and animation (like for example when adding an UIPopoverViewController)?</p>
