Transparent Buttons in iPhone SDK

Question

Hello!

I'm trying to create a transparent button in my iPhone app -- to create an Easter Egg of sorts. How would I go about setting the button to be transparent without touching the alpha (when alpha = 0.0 on a UIButton, it no longer responds to touch)?

Thanks. :)

Answer 1

You could set the alpha to a very small value.

Or, you could create a blank, clear UIImage and use a custom button style, and set it to the button's image.

Answer 2

Can you create an image as a button? Or use the button background the same color as the background (same effect as being transparent)?

Answer 3

Set your button type to UIButtonTypeCustom and it will have no styling. (thus, it should be "invisible").
