使scrollview的内容适合scrollview超级视图

Question

I have the following view hierarchy :

View1 (root view)
 Scrollview
  View2

I use auto-layout and I would like the view2 to fit to the view1 size. In the past, to solve ambiguous scrollable content, I programmatically added a fixed constraint for the view2 width and height. But I would like to know there is a nicer way to do it.

Answer 1

It is actually quite simple. Set two constraints linking View2 and Scrollview ( Superview actually) with Equal Widths and Equal Heights . This can be done in the xib file or programmatically.
