Gray box at bottom after animating uiwebview

[anubhab123]

Hi

I've been trying to animate a uiwebview by making it's frame shorter height using the UIView animateWithDuration:animations: method. I succesfully shorten the uiwebview by making the frame property equal to a shorter height however when i scroll to the bottom of the uiwebview I find a grey box.

After I animate the uiwebview to be shorter height I animate the uiwebview to be longer height(back to normal height it was originally)and the grey box disappears(and its animated too). I'm wondering if anyone has any idea how I can get rid of the grey box at the bottom of the uiwebview when i animate it to be shorter(via the frame property).

Just so you know:

I've tried reloading the webview(via the reload method).

I've tried setNeedsDisplay.

I've tried settings the contentMode to redraw.

Scales Page to Fit is off(I'd rather that it be off because otherwise my content shrinks too much).

Any ideas on how I can get rid of the grey box at the bottom?
