I use UITextView in my app. It contains a text and some URL links in it. I recognize the tap (double tap in Voice Over) on that UITextView and perform some action (overwriting default edit action).
When using the app in regular mode (Voice Over - off) the links are detectable and working (after a long tap on them).
When using the app in voiceOver mode the app does not detect URL links in that text view and does not enable activation of them.
