I want to change the background color of my UIAlertView, but this doesn\'t appear to have a color attribute.
I don't believe that there is an exposed method or property for doing this. Setting the backgroundColor of the UIAlertView (as a UIView) merely puts a colored rectangular backdrop behind the alert view.
I'd say that it would probably go against the common interface of the iPhone to alter this color, so I don't think it's recommended behavior (in the same way that changing the background color of an alert view in Mac OS X is not recommended).
