What does this look like when it prints?

Ah yes, I meant to include an example output, thanks for asking!

For a view controller, something like:

<XXXViewController: 0xdddddddd>: didTapButton:

If there are multiple actions:

<XXXViewController: 0xdddddddd>: didTapButton:, didTouchButton:

The output would be messier if the target provides a verbose -description method. Perhaps this shouldn't rely on the built in -description and should instead manually format the <Class: 0xdddddddd> string.


print '{target}: {actions}'.format(target=targetDescription, actions=actionsDescription)
