How can I make visual keyboard appear above my UIToolBar?

I have a UITextView at the middle of a View, a UIToolBar at the bottom of a View. I want a visual keyboard to appear above a UIToolBar when开发者_运维问答 I touch on UITextView. How can I do it?

You can't. The position of the keyboard isn't under the control of the application. (Oh, you could muck around in the UIApplication's UIWindow list to find the keyboard window and move it, but then Apple wouldn't accept your app.)
