title: How could we possibly create this ui concept?
body: <p>I came across this UI Concept, I couldnt help but to admire it's beauty.</p>
  
  <p>I am wondering if it is possible to create a Button that makes (mask) the control below them, to make them look transparent in that area. (In this case UITextField) </p>
  
  <p>Please take a look at this image below</p>

  <p>ANy idea if this is possible to be done via code?
  Please look at how the button makes the UITextField become transparent with margin.</p>
