I am trying to implement a control to edit text that will display the text in multiple colors. None of the solutions I have attempted yet have been good enough.

1. UITextView cannot accomplish this. All of the text must be the same color.
2. Using CoreGraphics to draw the text does not allow the text to be selected.
3. Using a UIWebView, DIV and PRE tags cannot be set to contentEditable on Mobile Safari.
4. Currently playing with using an off-screen TEXTAREA and an on-screen DIV to show the rendered text. This works pretty well, except supporting all of these at the same time seems impossible: click-to-type, click-to-move-cursor, click-and-hold-select/copy/paste.

Anyone have any tips on this predicament?

I've been trying to find any preexisting library out there that will accomplish this in a good way, to no luck. I'm open to any ideas!
