How to preserve a UIButton size after adding to a UIStackView

Question

I am still learning iOS development with AutoLayout and UIStackView, so bear with me.

Basically I add a UIStackView and UIButton separately on my storyboard's view and then I set a random height to my UIButton and afterwards I add my UIButton to the UIStackView.

My question: Why doesn't my UIButton preserve its height after adding to the UIStackView?

Any help here, It will be appreciated so much thanks!

确保将高度约束添加到uibutton中，否则将其添加到Stackview时高度将被覆盖
