I was linked to this post by Mark Wilson via a tweet from Tim O'Reilly:

This critique of an Apple ad may well be the most important thing you'll read this year: http://bit.ly/115U5uT Take it seriously.

My terse comment on Twitter summed up my response, but I decided to follow O'Reilly's lead and “take [the piece] seriously.” I'll try to keep it short.

Fresh clone and test of script/ci:

To form a parent-child relationship:

1. Send the -addChildViewController: message to the parent with the child as the parameter. This will send the -willMoveToParentViewController: message to the child with the parent as the parameter.
2. Add the child view controller's view as a subview to the parent view controller's view.
3. Send the -didMoveToParentViewController: message to the child with the parent as the parameter.

For example,

[parent addChildViewController:child];
