Customizing the UIPopoverController view background and border color

Question

Is it possible to change the border color, navigation bar style/color, and arrow style/color of a pop over view? If so, how? If some sample code is available, then that\'ll be g

Answer 1

I try to trick it by customizing the viewcontroller inside the popover and then hiding the popover border using this code

UIView * border = [[insideViewController.view.superview.superview.superview subviews] objectAtIndex:0];  
border.hidden = YES;

The app is actually still in development so I'm hoping other people will comment on this solution.
