Handle the problem of accessory views showing on top of the right button...

Hi Chris.

This is my solution to handle the problem of accessory views:

Store accessory view information in an instance variable.
When the scrollview is scrolled, set the accessories to none so that
they are not shown when the buttons are exposed.
When the scroll view is back in the center (or moved to the right),
restore the saved accessories.

Cheers!
