A UITableViewCell could be deallocated as soon as its row scrolls out of view.
UITableView will reuse cells if you specify a reuse identifier, but I don't
believe that the docs actually specify the number of cells that are reused.
I'm assuming that the web view is displayed when the user taps a link in the
UITextView. If so, when does the crash occur relative to the appearance of the
web view?
