It is only doable using CoreText, because it needs formatting attributes and NSAttributedString to display text with multiple font style and colors.

You may be interested in my OHAttributedLabel class that is a subclass of UILabel to render NSAttributedString (obviously it uses CoreText for this).

As setting the background color of a range of text is not directly possible/supported (no corresponding attribute in NSAttributedString), you may need to draw the yellow rectangles (before drawing the text) yourself, but I've done this in my class too to manage highlighted links (see drawActiveLinkHighlightForRect: method) so you may do a similar thing in your case.
