You can set and change volume using this way.

UISlider *slider_volumeControl=[[UISlider alloc] init];
slider_volumeControl.minimumValue=0;
slider_volumeControl.maximumValue=1;
[slider_volumeControl setValue:0];
[[MPMusicPlayerController applicationMusicPlayer] setVolume:self.slider_volumeControl.value];

Write method like this for slider value change event

-(IBAction)changeVolumeOnSliderValueChange:(id)sender
{
[[MPMusicPlayerController applicationMusicPlayer] setVolume:self.slider_volumeControl.value];
}
