Drag and drop UISlider and UILabel to view in xib. connect IBOutlet to interface variables and IBAction with event 'Value Changed'.


    @interface ViewController ()
    {
        __weak IBOutlet UISlider *slider;
        __weak IBOutlet UILabel *sliderValueLbl;
    }
    @end

    - (IBAction)sliderMoved:(id)sender {
        sliderValueLbl.text = [NSString stringWithFormat:@"%f",slider.value];
    }
