title: Objective-c: Dynamic size of UIStackView, depending of it's content
body: <p>I have an UIStackView which is inside a scrollview. the content of the stackView is dynamic, depending of how much views created and added with the methode "addArrangedSubview". if I have a few subviews, there is so much spacing between them, and if I have too much views, they become compressed. </p>
  
  <p>I have: </p>
  
  <p>_viewController</p>
  
  <p>|__ view</p>
  
  <p>|____scrollView</p>
  
  <p>|______stackView (dynamic content)</p>
  
  <p>I set the stackview to:</p>
  
  <ul>
  <li>Alignement: fill</li>
  <li>Distribution: equal spacing</li>
  <li>Spacing: 5
  and of course the constrains top/bottom/leading/trailing</li>
  </ul>
  
  <p>I want to increase the size of the UIStackview every time a view is added, and keep the size of my added subviews.
  Maybe something is missing or I have a bad understanding.. someone can explain to me how to do it ?</p>
  
  <p>I'm working with objective-c</p>
