滚动视图顶部间距

Question

I am very new to Auto Layout and generally iOS development. I have been struggling with the Top Space of my ScrollView for quite a while and I cannot figure out what causes it.

The red container is the ScrollView and the grey container is a view encapsulating several views (label, picker view and text field).

The desired result is that the grey container starts totally from the top.

This is how my layout and constraints look like:

Any ideas will be much appreciated!

Ok, so your scroll view warning for ambiguous content height was causing the issue.

I was able to resolve your issue by adding your scroll view inside a another view and adding missing constraints. For reference: UIScrollView Scrollable Content Size Ambiguity .

My changes did make some issues to your margins etc, but you can fix them based on your need. Please let me know if this resolves your issue.

EDIT: Added screenshot for constraints of the wrapper view as well.
