ios: uiscrollview and uiview autolayout

Question

I have uiscrollview and uiview . When uitextview is touched, uitextview size will be large size and uiscrollview size will be small size and there is a problem because of autolayout.

How can I set constraints of uiscrollview and uiview ?

Answer 1

May try it:
What I say below is about constraint:
UIScrollView top, left, right equal self.view top, left, right
UIScrollView bottom equal UIView bottom
UIView left, right, bottom equal self.view left, right, bottom UIView height equal 200(you set it)

OK, when you UITextView is touched, set the UIView height constraint to what you want(maybe 300)

I think it works!
