Answer 1

I have used this code. Get from: http://imagineric.ericd.net/2012/11/15/uislider-touch-to-set-value/

UITapGestureRecognizer *gr = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(sliderTapped:)];
[slider addGestureRecognizer:gr];



- (void)sliderTapped:(UIGestureRecognizer *)g {
        UISlider* s = (UISlider*)g.view;
        if (s.highlighted)
            return; // tap on thumb, let slider deal with it
        CGPoint pt = [g locationInView: s];
        CGFloat percentage = pt.x / s.bounds.size.width;
        CGFloat delta = percentage * (s.maximumValue - s.minimumValue);
        CGFloat value = s.minimumValue + delta;
        [s setValue:value animated:YES];
    }

Hope this can help you.
