How do I get a button with the a specifyed tag
id like to then cast it to a UIButton, and change the alpha
A:
UIView* view = [theViewContainingThatButton viewWithTag:tag];
view.alpha = 0.5;
You don't need to cast the view to a UIButton to change its alpha. But you can add a (UIButton*) cast if really needed.

@Sam: Any superview of that button can be used. You could use `viewController.view` or even `window`.
