UIView subview autolayout issue

I have UITableView Cell in which 4 UIViews are arranged in a vertical order like this,

enter image description here

In each UIView, I have two Labels like this,

enter image description here

I have taken a IBOutlet for Height Constraint of all of the Four UIViews and I want to make the height 0 of the view when data is not available in that view. The problem is View is not getting 0 height due to the 10 px bottom constraint of UILabel inside that View.

What i am getting is like this,

enter image description here

Code where constraints are handled

    NSString *toName = [self jointNameFromArray:evidence.arrTo];
    if ([Utility isEmptyString:toName]) {
        cell.toViewHeight.constant = 0;
    }
    else {
        cell.lblToName.text = toName;
    }

    NSString *fromName = [self jointNameFromArray:evidence.arrFrom];
    if ([Utility isEmptyString:fromName]) {
        cell.fromViewHeight.constant = 0;
    }
    else {
        cell.lblFromName.text = fromName;
    }

    NSString *ccName = [self jointNameFromArray:evidence.arrCc];
    if ([Utility isEmptyString:ccName]) {
        cell.ccViewHeight.constant = 0;
    }
    else {
        cell.lblCCName.text = ccName;
    }

    NSString *custName = [self jointNameFromArray:evidence.arrCustodian];
    if ([Utility isEmptyString:custName]) {
        cell.custViewHeight.constant = 0;
    }
    else {
        cell.lblCustName.text = custName;
    }    
     [cell layoutIfNeeded];

If you're targeting iOS 9+, I'd suggesting using UIStackView, as it does exactly what you want just by setting the .hidden property of your view to true.

If you are unable to use UIStackView, you will need to set one of the vertical padding constraints to a lower priority than the height constraint. You will also need to set .clipsToBounds to true.
