UISlider not sliding in prototype cell

问题

I have designed a prototype cell in a Storyboard's view controller, but unfortunately the UISlider in the cell is not sliding.

Note:- Autolayout is enabled for this storyboard.

Design:-

Here is code:- to render the cell in UITableview

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    UITableViewCell *cell;
    if(indexPath.row!=self.arrSelectRecipientsImages.count-1 )
    {

        cell = [tableView dequeueReusableCellWithIdentifier:@"selectReciptenceTabCell" forIndexPath:indexPath];

    }
    else
    {
        cell = [tableView dequeueReusableCellWithIdentifier:@"selectNearbyTabCell" forIndexPath:indexPath];
        UISlider *sliderNearby = (UISlider *)[cell.contentView viewWithTag:199];
        lblDistance = (UILabel *)[cell.contentView viewWithTag:190];
        sliderNearby.userInteractionEnabled = YES;
        [sliderNearby setThumbImage:[UIImage imageNamed:@"NearbyCircle"] forState:UIControlStateNormal];
        [sliderNearby addTarget:self action:@selector(sliderNearbyAction:) forControlEvents:UIControlEventValueChanged];
  }
return cell;
}

The code is working fine I think. Also no need to set user interaction.

Here is the example code may you get help form it. It is working fine with autolayout.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];

    UILabel *lblTitle = (UILabel *)[cell viewWithTag:100];
    lblTitle.text = @"Hi";

    UISlider *slider = (UISlider *)[cell viewWithTag:101];
    slider.value = 0.2;
    slider.tag = indexPath.row;
    [slider addTarget:self action:@selector(sliderNearbyAction:) forControlEvents:UIControlEventValueChanged];
    return cell;
}

- (void)sliderNearbyAction:(UISlider *)sender{
    NSLog(@"Slider %ld Value : %.2f",(long)sender.tag, sender.value);
}

OUTPUT with Log :

Well, the problem was very silly, I have not provided height for cell in different index-path.That's why the last cell i.e the slider cell was showing but it's height was 30, so any tap or gesture outside that region was not responding.
