Short question: What's the best way to scroll a UIWebView slightly from its current position when there's a keyboard present? I already tried -[UIScrollView setContentInset:], but that does not work when a keyboard is on screen.
Long question:
I have a UIWebView, and I'm trying to graft a custom keyboard extension onto it that will appear on top of the keyboard. Since UIWebView doesn't support -inputAccessoryView, I've made this happen by listening for UIKeyboardWillShowNotification, and then adding the extension view as a subview when the notification is received.
This works fine, except that the spot the user is editing might appear underneath the keyboard extension, so I need to inset the scroll view in order to compensate for this or the user won't be able to see what they are editing. So I tried adjusting the scroll view's content inset, but I noticed that UIWebView makes its own adjustment to the content inset whenever the keyboard appears, and the attempt to change it twice in a row seems to cause the content inset to change to some other number internally for some reason. So how do I move the scroll view slightly if adjusting the content inset won't work?
