title: slider to change background color
body: <p>I'm making an iPhone app that has a slider. I want the user to be able to change the background color as they slide along. I was going to have say 5 colors available and slider value from 0-5. The default background color is yellow. I can't find, how to make changes to the background as the slider moves along.</p>
