How to use Freeform Simulated Size to change height of scrollView but not width

Question

I am using the Freeform simulated size to change the View Controller height so I can arrange all subviews in a scrollview .

• I set the height to 1200
• Add a scroll view; set the constraints to the superview
• Then add a UIView called bodyView to the ScrollView to be the container of the body content and set all margins to the scroll view.

• Add another UIView to be the header with a fixed height of 400 but set the rest of the margins to the BodyView to stay at the top and to be the same width.

  • Add a UIImagevView to the headerView and set all constraints to the header

This is how it looks so far:

However once the UIViewController is run on smaller device sizes the scroll view retains the original width of 414 and the content does not fit in the frame; even though there is no width constraint set for neither of the sub views.

Does anybody know where I am going wrong and what might be happening ?

I have been researching and even checked out other projects and cannot seem to replicate/resolve the issue.

bodyView必须从外部scrollview获得其宽度，因此，将Control从bodyView拖动到viewController的视图并选择Equal- Widths-高度是根据从上到下的钩子元素计算的
