How can one programmatically reorder items within a UIStackView in IOS?

(i.e. I can not see a function at https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIStackView_Class_Reference/#//apple_ref/doc/uid/TP40015256-CH1-SW30 to cover this)???

回答1:

surely you can use a combination of

removeArrangedSubview(_:)
insertArrangedSubview(_:atIndex:)

to reorder your views?

回答2:

When adding a view to a parent view, it is automatically removed from it's old parent view.

This is the same with arrangedView, so you only need to use insertArrangedSubview(_:atIndex:) and addArrangedSubview().

Using removeArrangedSubview() is not needed.
