title: Check current responder?
body: <p>I'm making an application that requires the use of multiple textFields with number pads as there first responder. I have created an image to use as a negative button that will be an addition to the number pad.</p>
  
  <p>I am wondering if there is a way to check which textField the number pad is typing to.</p>
  
  <p>Any help would be appreciated!</p>
