IOS keyboard active but invisible when listening to UISearchBar

I have a problem that runs exactly as shown here. https://www.youtube.com/watch?v=Fup-WrgN3wA I am not the owner of this video and cannot find any meaningful solutions to the problem described in it.

In my case: I have a UITableView with a UISearchBar. Touching the UISearchBar makes it the firstResponder with a blinking cursor, ready to accept keyboard input. However, the keyboard is invisible but still clickable.

If I leave it in this state for 10-20 seconds, the keyboard magically appears on its own for no reason.

Has anyone experienced this and what has been done to solve it?

I've tried UISearchBar / UISearchBar and Search Display / UITextField - with the same results at all.

Latest version iOS 8.1.2 Latest Xcode 6.1.1

Thanks in Advance
