ios - UIStackView Distribution Fill Equally

Question

So, I have a UIStackView that contains four (4) UIViews. If I remove one (1) of those UIViews, the other three (3) will fill the entire space in the UIStackView.

MY QUESTION:

How can I add a max height on a UIView so that it won't fill the entire space of the UIStackView even though the distribution is filled equally? I read something about adding a constraint but I'm not able to make it work. I'm using swift by the way.

Thank you.

As a confirmation, this is the current behavior:

And this is what are you asking for is:

In order to achieve it, you could follow this simple trick:

P.S: I assume that you added the needed appropriate constraints for your stack view.

If your stack view doesn't have a "height" constraint, add one:

Now, add it as an IBOutlet to the assigned ViewController; In my example, I'm calling it stackHeight:

@IBOutlet weak var stackHeight: NSLayoutConstraint!

On the event that you want to hide the view (in my example, I'm hiding the orange button based on IBAction assigned to itself, when tapping on it, should be hidden), you need to get the height of the view that you want to hide and subtract from stackHeight.constant:

    @IBAction func orangeTapped(_ sender: AnyObject) {
        orange.isHidden = true

        // here we go:
        stackHeight.constant = stackHeight.constant - orange.frame.size.height
    }
