Is CoreText just a draw/layout Framework for text?

Im using CoreText to display some text, creating framesetter, frames and so, and everything is fine. I can even format the text, but this all is done before I draw. Now the question that is driving me crazy:

CoreText is just to render text? I cannot get any reference to CTRuns or Glyphs to highlight them?

Another sub big question, the Pages App dont use CoreText, anyone knows? In Pages, you can select any already drawn styled text!

All I want is to draw the text and be able to let the user tap to select any text or doubleTap to select the paragraph.

Please, anyone, any light?

Thanks in advance.

CoreText is just to render text. Implementing user interaction is quite another matter. You need to implement UITextInput protocol, see here. It's a big job.

If you just want to input text and don't have a need for advanced typography, just use UITextView or UIWebView.
