Answer 1

The Control Events documentation will list all of the events you can subscribe to for controls (in this case, your UIButton). The one you want is UIControlEventTouchDown. But the problem with your requirement is that pushing the button covers the screen with the user's finger and I wonder whether changing the title will really be beneficial.
