title: Cocoa: Parse NSString by character length
body: <p>I have an NSString I'm working with, but I would like to parse it by character length.  So break it apart into an NSArray, and have each object in the array be x characters from that string.  So basically, break up the string into sub strings of a certain length</p>
  
  <p>So, how do I do it?</p>
  
  <p>example:</p>
  
  <p>NSString  *string = @"Here is my string"</p>
  
  <p>NSArray objects:</p>
  
  <p>"Her"</p>
  
  <p>"e i"</p>
  
  <p>"s m"</p>
  
  <p>"y s"</p>
  
  <p>"tri"</p>
  
  <p>"ng" </p>
