From the WWDC 2014 video 216: "targetViewControllerForAction works by looking at the View Controller and seeing if it's _overwritten_ the action method that you've passed in."
From Kyle Sluder's blog: "-targetViewControllerForAction:sender: ... will then determine whether the instance’s method for that selector is an override of a UIViewController implementation for the same selector." Those descriptions are correct. But then how do you suppose it does this? There's an introspective voodoo happening here that I've never seen before. `respondsToSelector:` obviously doesn't cut it: it would return YES if this class merely _inherits_ the ability to respond to this selector. How would you find out the answer to the question, "does this UIViewController subclass respond to this selector _differently_ from UIViewController?"
