Set subview height relative to parent view in Storyboard

Question

I have a UIImageView in a UIViewController's view. What I want is to set it's height 1/3rd that of the view no matter what the screen size is. I of course know how to do this from code. But how to accomplish this using Storyboard/Interface builder only ?

Answer 1

Add a height constraint whose multiplier value is 1/3 so the image view's height will be one third of its superview's height.
