如何强制scrollview在Xcode中只垂直滚动

Question

I want my ScrollView to only scroll vertically but it also scrolls horizontally. I have the leading and trailing constraints set to 0 but somehow it is still adding space to allow it to scroll.

When I click on the embedded view or scroll view, I see the red lines to the left and right but not sure how to prevent them from being added.

Answer 1

You must set scrollview's contentView width is equal to superView(device Width). Than after your scrollView stop scrolling horizontal.

Thanks.

Answer 2

Follow the routine of creating a vertical scroll view.

• First, You need to change Simulated Size to FreeForm.
  

• Second, Put in a ScrollView, set up Constrains.
  

• Third, Put a View on top of it, set up Constrains.
  

• Fourth, set the layout for SuperView.

• Fifth, change Priority and Mutipier

And now we can work up here !
