How to center text vertically in UILabel?

Question

iOS

I have a UILabel whose text is automatically sized to fit the available width:

label.adjustsFontForContentSizeCategory = true
label.adjustsFontSizeToFitWidth = true

On the Layout, this UILabel has 4 constraints:
Center on X and Y; indents left and right.
If you enter a short text, then the text in the UILabel is in the middle (x = y):

If you enter a long text, then the text "goes down" (the font size automatically decreases, the distance from the top border of the UILabel to the text increases). At the same time, the height of the UILabel itself does not change.

How do you center text vertically?

Answer 1

As I see it, there are no clear rules "what to do in what situation"
For example - why should the text be transferred to the second line, and not reduce the font so that all the text fits?
If you have a clearly defined logic in your head of how the text should look in different cases, then it is better to describe it in logic and turn off autofit. Because you don't know what rules she uses.

Answer 2

I didn’t understand the question, but with given constraints, your text will always be centered, regardless of its content
