UIStackView : Is it really necessary to call both removeFromSuperView and removeArrangedSubview to remove a subview?

Question

From the UIStackView Class Reference

In removeArrangedSubview:

To prevent the view from appearing on screen after calling the stack’s removeArrang

Answer 1

You're right, just the call to removeFromSuperview is sufficient to have the view fully removed.

I suspect the reason for people putting both is because they run across the removeArrangedSubview documentation which seems to say both are needed. (And indeed, they are, if you call removeArrangedSubview and want the view really gone.)

The additional doc in arrangedSubviews is not seen by so many, so they don't realize removeArrangedSubview is, in this case, optional.
