ipad: Easy way to customise the UIActionSheet look & feel to be like the one in Safari?

Question

Hello all

This is the default look & feel of UIActionSheet.

The border of the view is very thick with black colors, the overall looking is very bold and heavy.

This is the one Safari has

You can see that the border is very thin, and overall looking is more light and simpler

Can someone tell me how do i customise the default UIActionSheet view to the one in Safari? make it more simpler and lighter?
