XIB Links and Phone Numbers detection color

I find that auto detection of links and phone numbers in xib textfields is very useful,

is it possible to change the color of the autodetected link or number?

In a UIWebView the detected data is just rendered as a link, so CSS will let you change that. In the UITextView, there isn't a method to make the change, so I would guess that you cannot. Additionally, you run afoul of the iOS GUI guidelines by making a link a color other than blue.

If you're dead set on changing the link colors then I would render your text in a UIWebView instead of a UITextView and use CSS. I wouldn't try to use UITextViews and private API's.
