Setting Alpha Value to Zero in IPhone Interface Builder Renders Button Unclickable

Question

I am trying to make a button that is invisible but that can still be clicked. Setting the 'Hidden' property to true makes it non-clickable as does setting the alpha value to zero. Setting the alpha to.02 makes the button work, but also makes it slightly visible. Any suggestions?

Answer 1

Try setting the button type to Custom, this will hide the default style of the button

Answer 2

This is quite simple to do. Just forget about alpha parameter and use Custom instead of RoundedRect in the Button Attributes->Type.

Answer 3

Change it to custom or 0.01, custom makes it not visible, you could also set the alpha programatically to 0.0000000000000000000001 like this, [//outlet setAlpha://ur number];
