title: Get all characters to end of line after identifying prefix characters iOS
body: <p>I have a single raw string that prints as follows:</p>
  
  <pre><code>DCBNONE
  DBA12292018
  DCSJACKSON
  DACJOHN
  </code></pre>
  
  <p>I need to pull the first name (DCS) and last name (DAC).</p>
  
  <p>How do I pull these characters out by first identifying the prefix (DCS) and then grabbing all characters to the end of the line in Objective-C?</p>
