title: Removing separator between 2 UIPickerView components
body: <p>So i'm trying to do something in my application, but without any success. I have this <code>UIPickerView</code> he has 3 components. The first component is numbers from 0-1000, the second is measure and the third should be a word, but it has to be non scrollable. It should look something like this:</p>

  <p>Does anyone can please tell me how to remove the separator between the 2nd and 3rd components, and how to add a text like this that doesn't move when touched?</p>
  
  <p>Thank you very much!</p>
