Getting the Value of a UITextField as keystrokes are entered?

It turns out, the easiest way to do this is using Interface Builder:

  • Add a IBAction (to the ViewController, say, as in this case)
  • Ctrl-Click (or right click) on the UITextField in Interface Builder
  • Connect the “Editing Changed” event to the File’s Owner’s IBAction added in the first step.

Works like a charm 🙂 (I can’t believe I spent numerous days on this, and to realize now that the solution was much simpler than I’d thought :P)
