sizeToFit UIButton when programmatically added to UIStackView

Question

After much searching I have started to give up

I have an iOS app (swift) that asks the user a series of questions and answers. The questions and answer are downloaded from a JSON file. There will always be 1 question per page but a varied number of answers. So the answers are UIButtons added to a UIStackView which is created in the xib. Here's the slight problem.

If I create an answer with more than 1 line (i.e. It has a line break in it), it will create a new line in the UIButton.titleLabel and expand the UIButton to fit. However, if the answer is long and spans over more than 1 line the UIButton does not expand. I have line wrap enabled to the label wraps correctly, however the button doesn't seem to realise it's width constraint within the UIStackView and therefore assumes it can display 1 long line of text and creates it's height accordingly - even when I call the ever trusty sizeToFit()!!!

I assume there is a simple setting such as "contentWidth" I am missing.

P.S. I would prefer not to calculate the size and manually set the height of the button. I want it to work with rotation as well which of course resizes the width

Answer 1

Okay I never found a fix for making the Button resize to it's own UILabel size correctly, it seems it constantly sees the text being able to fit to one line and work.

I did overcome the problem by replacing my UIButton with a UILabel. The UILabel then has addGestureRecognizer(UITapGestureRecognizer()) and of course userInteractionEnabled = true

It's not the way I would like it to be but will keep my client happy until the next update to UIStackView!
