Background of AlertView is an image And you can change this image



UIAlertView *theAlert = [[[UIAlertView alloc] initWithTitle:@\"Atention\"
   message: @\"YOUR MESSAGE HERE\",nil)
   delegate:nil cancelButtonTitle:@\"OK\" otherButtonTitles:nil] autorelease];

    [theAlert show];

   UILabel *theTitle = [theAlert valueForKey:@\"_titleLabel\"];
   [theTitle setTextColor:[UIColor redColor]];

   UILabel *theBody = [theAlert valueForKey:@\"_bodyTextLabel\"];
   [theBody setTextColor:[UIColor blueColor]];

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

   UIGraphicsBeginImageContext(theSize);    
   [theImage drawInRect:CGRectMake(0,theSize.width,theSize.height)];    
   theImage = UIGraphicsGetImageFromCurrentImageContext();    
   UIGraphicsEndImageContext();

   [[theAlert layer] setContents:[theImage CGImage]];
