title: Create Overlay above UIButton in iOS?
body: <p>How to create an overlay above a UIButton in iOS?</p>
  
  <p>In my projects there are 6 UIButtons.</p>
  
  <p>For each button I need to have an overlay instruction above that UIButton, means both UIButton and overlay should be visible.</p>
  
  <p>Once a user clicks on the overlay above the UIButton, overlay will remove/hidden and UIButton should be visible.</p>
  
  <p>How can I achieve this?</p>
