There's nothing built in to iOS that will do this. Some broad techniques that might work:

  • If you're showing the book in a web view, you might be able to wrap that area in a span and style it to create a highlight.
  • If you're using Core Text, you could draw the highlight in directly, either before or after drawing the text. (Your choice will decide how the highlight affects non-black text.)
  • You could add a transparent view over the text that draws in the highlight.

As for adding highlight-related items to the selection menu, see this Stack Overflow post. You probably won't be able to get icons in the menu like Apple does, though; that seems to be a private API. You could probably override the whole menu system if you want something closer to Apple's look, but that'll be quite a bit of work.
