I have 4 labels on my storyboard, aligned at baseline and with fixed distance between them.
Each label can have different values at runtime, and I would like that the group of these 4 labels is horizontally centered.
Didn't succeed to fix it !
I tried to put them in a view and center the view, but it doesn't work either.
Tried also to play with priorities, but didn't't succeed either...
Is it possible to achieve that in the storyboard ?
You can do this by putting your 4 labels inside of another view. Add the following constraints:
Set fixed distance constraints between the labels (3 constraints).
Set constraints to align the baselines of the labels (3 constraints).
Set a leading constraint from the leftmost label to the containing view. Set the constant to 0.
Set a trailing constraint from the rightmost label to the containing view. Set the constant to 0.
Set a constraint for the height of the view.
Set a constraint from the top of the left label to the top of its containing view.
Set a constraint to center the view horizontally.
Set a constraint to position the view vertically.
The width of the view will be determined by the intrinsic sizes of the labels plus the sizes of the distances in #1. This width will change as the contents of the labels changes, and the view will keep the group centered.
You can use a Stack View for this:
In the 'Attribute Inspector' you can set for example that each text field has an equal width and a spacing of 5 points between them:
You can then use your Stack View to center horizontally like your normally would do.

I am trying to set margins in the UITableView's cell, but it doesn't work. I set all constraints and nothing. The Labels are always in the same place - left top corner, but in the Storyboard it looks like I want. If I set the layout of a Label to Translates Mask into Constraints is fine, but then I can't set autoresize Labels. I have already made cells using the Automatic layout, but in this case I really don't know what's going on.
Based on the screenshot you posted I believe you're missing a trailing constraint on your City Label that goes from the right edge to the right edge of the content view.
I always make this last trailing constraint a "greater than or equal to" constraint to allow for the length of the content and different device widths.
I have a view controller with six buttons.
I want to show them in 3 rows and 2 columns.
I decided to put each column of buttons (3 buttons) in a stack view and put 2 vertical stack views in 1 horizontal stack view.
I want my buttons to look square shaped.
I applied following constraints for the horizontal (main) stack view:
Align Center X to Safe Area
Align Center Y to Safe Area
Align leading to Safe Area Equals:50
Aspect Width:Aspect Height = 2:3
For some reason aspect ratio is not working and the width is still
larger than the height and more importantly the buttons are not square shaped.
I tried to update frames, to apply all possible alignment and distribution properties, however, it didn't solve the problem. Please check images below for your reference.

I'm new to Swift and trying to repeat the calculator app as part of the learning, but got stuck at the autolayout.
Here's what I did:
Set each row as a Horizontal stack view, and all rows together as a Vertical stack view.
Set the vertical stack view Distribution as Fill Equally.
Set constraints for each Horizontal stack view as theTopView.bottom = theBottomView.top, and vice versa.
Set constraints of each element inside each Horizontal stack view as element.Top = stakcView.Top, element.Bottom = stakcView.Bottom.
Gap with distance set at 0:
However, there are always gaps between the Horizontal stack views, despite showing the distance between them being 0.
Can someone tell me what I did wrong? Why are there gaps despite showing 0 as the distance between these two? Your help is really appreciated!
constraints:
A UIStackView arranges its subviews. Don't try to add positioning constraints between the arranged subviews - that counters what you've told the stack view to do.
You need to decide how you really want your buttons to look.
In this case:
The 0 label is not contained in any stack view.
I gave the % button an aspect ratio of 1:0.75.
The "outer" Vertical stack view and the Horizontal stack views are all set to Fill Equally.
Here are the constraints - the only difference between the 3 layouts is:
1-> Left image has the "outer" stack view centered vertically - no Top or Bottom constraint.
2-> Center image has the "outer" stack view Bottom constrained to the view Bottom (of safe area).
3-> Right image has the "outer" stack view TOP constrained to the Bottom of the "0" label.
If you want the buttons to fill the screen:
Remove the Aspect Ratio constraint from the % button.
Outer stack view has Top constrained to label Bottom, and Bottom constrained to view Bottom (safe area)
Thanks for your answers!
While they are all informative, fundamentally, my problem lies somewhere else: there are always mysterious gaps between stack views regardless what the constraint constant is set to.
For example, it was set to 0
Space between stackviews when set to 0
Then it was set to 20000
Space between stackviews when set to 20000
Then I discover that it was the space setting was accidentally set to larger than 1. When I set it to 1 the mysterious gap went away.

Problem solved. Thanks again for your help!
Try "Fill" instead of "Fill Equally"

Pic.1 - it is a structure of my ViewController. Label1 and Label2 have changing size (content comes from backend) for different users. If content of labels is small, I need to set Top Space constraint for TableView (vertical spacing) to Button (pic.1), but if content of labels is big, set Top Space constraint for TableView (vertical spacing) to Stack (pic.2). How to set constraints for TableView?
Embed your image,button two labels and stack in a view.
Then add following constraints
Top, leading and trailing to new container view
vertical space b/w container and table.
Required constraints for your image,button two labels and stack
Don't add bottom constraint for button.
Add bottom spacing to stack to its superview(embedded container) with a >=.
Height to container view with minimum height and set priority to low(250)
I have two StackView, one of which is horizontal and another vertical.
For the horizontal StackView, I want the items to be aligned to the left and grow toward the right.
For the vertical StackView, I want the items to be aligned to the top and grow downward. For example the position of the top item would never change but the stackview expands down if another item is added.
I'm having trouble accomplishing this, for example with my horizontal StackView, if I have two items 40x40, they will example the entire width of screen for some reason and I've tried a whole slew of different variations of distribution, alignment and constraints.
For my vertical StackView, if I add two items, my first item will move up and the second item will go underneath, so the center is now between the two instead of the first item staying still and the second going underneath it.
I can't figure out what I'm doing wrong here and how to just get StackViews where the first item is sized correctly, in place, and future items follow it, expanding either rightwards or downwards.
What you need is for Vertical
1- Drag a UIStackView with top , leading and trailing constraints to the superView
2- Drag any view inside it and give it a height constraint
for Horizontal
1- Drag a UIStackView with top , leading and height constraints to the superView
2- Drag any view inside it and give it a width constraint
Note : Make distribution set to fill
