title: Changing Device Volume
body: <p>I am developing an Iphone/Ipod Application, in which I am using AVAudioPlayer. I am changing volume of audio through slider, which works correctly, but now I have to change(increase/decrease) slider by pressing the device plus and minus button instead of changing slider by myself. When I press plus/minus button of device, don't know where the control goes? Does anybody know, feel free to help.</p>
