How can I render different paragraph styles in Core Text?

I'm having a difficult time trying to work out how to build a page using Core Text, where I have multiple paragraphs which follow one another, but in different styles.

In other words, I would like to have a title paragraph, followed by a subtitle paragraph, followed by several body paragraphs. In HTML terms, this would be:

<h1>Some title</h1>
<h2>Some subtitle</h2>
<p>Blah blah...
         ...</p>

I have got as far as creating a CTFramesetter for the title, creating a CTFrame from that, and then drawing it to the context. However I don't understand how to create a new frame which flows on from the previous paragraph. Can anyone help please? Or is there some good online tutorial to help?

Thanks!

Solution

The easiest way to do this is to just style your NSAttributedString with the different styles before you create any framesetters.
