If you want an easy way to let users know when a
UIButton was tapped, try setting its
showsTouchWhenHighlighted property to be true. This will render a circular glow effect behind the button when it's tapped, which is particularly effective on text-only buttons.
Here's the code:
btn.showsTouchWhenHighlighted = true
If you're using Interface Builder, look for and check the "Shows touch when highlighted" option for your button.
Available from iOS 2.0
