cocoa/iPad How do I keep a UIButton clickable when its alpha == 0?

Question

When I set a UIButton's alpha to 0, it behaves as if it isn't enabled. I've checked and, even though the button does remain enabled (though invisible (but not hidden, I checked that as well)), it ceases to work.

Is there any way to keep it clickable even when its alpha is 0?

Answer 1

UIButtonStyle set to "custom". And instead of alpha 0, you need to set background to 'clear color'.

Answer 2

Try to put another UIButton on top of it with it's UIButtonStyle set to "custom" and just leave it as it is, except of adding your IBAction to it.
