set UIButton's buttonType programmatically [duplicate]

Question

I have a UIButton which I've added in IB, however the view behind this button changes color and I need to switch the button's type between InfoDark and InfoLight. Bizarrely though, buttonType property is read only. So how can i switch between light and dark info buttons?

Answer 1

You can't set buttonType readonly property, use below may help:

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];

Answer 2

There's no way to change the .buttonType once it's set.

You can prepare two buttons, and hide one of them depending on the background color.
