iphone - How to change UIAlertView text color?

I'm currently using http://kwigbo.com/post/318396305/iphone-sdk-custom-uialertview-background-color for my custom UIAlertView. Everything is working fine but I'm trying to change the title and message text colors and I would like to change the button color. Is there any way to do this? I've tried using:

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

but I can't get it to work. Any help would be appreciated. Thanks.

You just need to include UIAlertViewDelegate in your .h file and override this method in your .m file.

-(void)willPresentAlertView:(UIAlertView *)alertView{
    UILabel *theTitle = [alertView valueForKey:@"_titleLabel"];
    theTitle.font = [UIFont fontWithName:@"Copperplate" size:18];
    [theTitle setTextColor:[UIColor whiteColor]];

    UILabel *theBody = [alertView valueForKey:@"_bodyTextLabel"];
    theBody.font = [UIFont fontWithName:@"Copperplate" size:15];
    [theBody setTextColor:[UIColor whiteColor]];
}
