问题 I'm trying to build an iPad app that uses custom images as buttons with my own custom behaviors when the buttons are selected, touched up inside, outside, etc. I'm trying to use Interface Builder to do this, but I have a lot of questions as to what the various text fields mean such as Background Image, Shadow Color, Shadow Offset, Highlight Tint, Drawing, etc. Does anyone know of a good tutorial that goes over UIBUttons on Interface Builder? 回答1: Probably the best online custom button
