At some point in my app I have a highlighted
UIButton (for example when a user has his finger on the button) and I need to change the background color while the button is highlighted (so while the finger of the user is still on the button).
I tried the following:
_button.backgroundColor = [UIColor redColor];
But it is not working. The color remains the same. I tried the same piece of code when the button is not highlighted and it works fine. I also tried calling
-setNeedsDisplay after changing the color, it didn't have any effect.
How to force the button to change the background color?
