A UISlider represents a graphical bar with a slider that you can adjust.

Example
UISlider slider =
   [ [UISlider alloc]
   initWithFrame:CGRectMake(0,170,320,50)];

[slider addTarget: self
    action: @selector(getSliderValue:)
    forControlEvents: UIControlEventValueChanged];

[self.view addSubview: slider];




// use slider.value to get the value of the slider


-(void) getSliderValue: (id) sender
{
     // do whatever
     double sliderValue = slider.value;
}
