I am doing a customized keyboard. How to make those keyboard of letter button(A-Z) bigger while touching?
Look at the button's events. There're
UIControlEventTouchUpInside and some others. You should assign
IBActions to those events.
But if you have many buttons you'd better subclass UIButton and override it's
In these messages resize your button's frame according to your needs (you could even change it's background image or text size). But make sure superview of your buttons doesn't have
Clips Subviews attribute set.
