title: How to play a sound in objective C iphone coding
body: <p>I have an app I am working on and It uses some of the hardware sensors to provide data on screen, there is a Label that updates with the number.  I want a sound to play whenever the number is above 100 or something.  For example, say it was reading numbers then all of the sudden it finds a good spot (or whatever), then I would like a sound to play or a light to light up.  I am an absolute beginner and it would be nice if the answer would be easy for a absolute beginner to understand.</p>
