I am trying to change the background of the uialertview. Everything works fine except the background image i am adding to the uialert view won't scale inside the alertview. So basically you see only part of my background image based on the current size. Is there any way to make it so that the image scales inside the alerview until it fits?

UIAlertView *theAlert = [[UIAlertView alloc] initWithTitle:title 
                                                    message:msg
                                                   delegate:nil 
                                          cancelButtonTitle:@"OK" 
                                          otherButtonTitles: nil];
    [theAlert show];

    UIImage *theImage = [UIImage imageNamed:@"bg.jpg"];
    theImage = [theImage stretchableImageWithLeftCapWidth:16 topCapHeight:16];
    CGSize theSize = [theAlert frame].size;

    UIGraphicsBeginImageContext(theSize);
    [theImage drawInRect:CGRectMake(0, 0, theAlert.frame.size.width, theAlert.frame.size.height)];
    theImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    theAlert.layer.contents = (id)[theImage CGImage];
    [theAlert release];

Simply setting contentsGravity for layer doesn't work for alert view. Try with UIAlertView subclass. You can find more info Joris Kluivers :: iPhone Dev Resources here, but note that changing background of alert view is against iPhone HIG (ref: iPhone Human Interface Guidelines: Alerts, Action Sheets, and Modal Views, under Designing an Alert section)

Thanks. "You can’t customize the width or the background appearance of the alert view itself, or the alignment of the text (it’s center-aligned). "

ok so i am not changing the background appearance, i only change the color. the alertview looks exactly the same.
Is the color of UIAlertView considered it's appearance? hehe a little confusing
