View input accessories when an alert is displayed

Question

I am using input accessory view for my viewController to dock the view at the bottom of the screen and use the keyboard.

Everything works fine, except when an alert displayed, the input accessory view hidden. It opens again when the alert rejected. This leads to an unwanted failure.

I tried using the [alertView show] API, as well as the new alertController API. The problem exists in both cases. I need support from iOS7.0 .

Please provide your valuable comments or a solution to this problem.
