sliding UIView back after numeric keypad entry

Question

Hi,

I am working on an iPhone app is iOS 4 where I have managed to add the done button to the numeric keypad from an online blog I read. The done button is shown when the key pad pops up and works fine. I had to hook up to the KeyboardViewDidShow event handler and add the button image with the method for it. After I press the done button, the keyboard slides back but the UIview does not slide back to its original position.

I used the solution given at: http://www.neoos.ch/news/46-development/54-uikeyboardtypenumberpad-and-the-missing-return-key#idc-cover

I am pretty new to Xcode development and cannot figure out what else I need for the UIview to slide back? Any help is appreciated.

Thanks in advance!
