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 made some custom tableview cells and while everything else with them works, the images are really big and I cant get them any smaller.
I did this and its still flooding: I added height and width constraints and a 10 constraint to the left of the ImageView, and selected these settings
I can suggest a few things you can try to achieve it. I have illustrated 1 & 2 on the attached image:
Suggestion 1 is to make sure there is no ambiguity or constraint collision. It seems you have set two constraints for the width of your image. You might be setting it to be 'greater than' the width you want it to be.
Suggestion 2 is to also provide a constraint between the image view and your label view for the heading in order to prevent an overlap.
Suggestion 3 is to make sure that your imageView has a setting of "Clips to bounds' checked on the inspector.
Suggestion 4 Change your content mode to Aspect Fill instead of Aspect Fit
Suggestion 5 Complete your constraints, make sure everything is blue. I don't see top and leading constraint. This will help remove any ambiguity.
Suggestion 6 Use the view debugger, see what constraint values are being used, and the debugger will also show you hierarchies and view layers, which will give you more idea of what is going on.
Your imageView seems to have no x and y constraints. I suggest you to give top and leading constraints for the beggining. You should never see red lines to have stable layouts.
I am working with xcode and I can't seem to get my custom cell to budge. I have the constraints set up and even reset them a couple of times but they continue to look a lot different when I run my simulator.
Here is a screenshot of my constraints:
Here is an screen shot of my simulator:
I have tried deleting the labels and imageView and then adding it again and reset the constraints a few times. Anyone else getting these problems?
You are defining too many constraints. It is key for you to always use THE LEAST number of constraints as possible.
From what I can see you are giving the labels '5' and 'Orders need to be viewed' constraints to the leading edge of the cell. If you are also setting a second leading constraint to the image (hard to tell from the image, code would be easier to debug) this contradiction would break your constraints.
What you want is to have the image leading edge to the cell and give it a height and width and a top constraint only.
Give the '5' label 'horizontal spacing' ( ctrl drag ) to both the image and the second label.
Provide a height and width for it and a top constraint.
IMPORTANT
since you have defined a horizontal spacing from the '5' to the other label, you do not need to provide another leading constraint to the last label.
simply give it a height, width, top constraint and trailing edge to cell
That should be all you need !
If this is too confusing let me know and I can share some snippets for more visualization
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.
The scene has a container view inside of a superview, and I've constrained it with respect to the boundaries and 2 text boxes. Instead of "Numeric Value Please", I only see Nu... appearing on there. The console does not give me any constraint related warnings, and I don't understand why the blue view is able to fit in, but the controller is not.
Here are Alert Controller's constraints: http://i.stack.imgur.com/2xhZh.png. It's just constrained to the center.
Another picture of main view's constraints: http://i.stack.imgur.com/2qARq.png
The constraint to the right is too large (125), pushing the right edge of the container to the left.
You should just have: constraint from top (superview), constraint to left (the text field), height (optional), and slightly higher compression resistance. To prevent the text from going off to the right you can also have a >= constraint to the right (superview).
To break the text into two lines, set number of lines to 2 and choose "Word Wrap" + make sure you have a right side constraint and you are not constraining the height (too much).
Another remark: do you really need a "container" view? Why not just a plain UIView? Or does the label have its own controller? That seems like a somewhat convoluted design I think.
I am working on a Swift project with Storyboards where I want text to wrap in a label. In the old Objective-C version where I did not use a Storyboard I used the following settings and things worked perfectly.
Here are the settings for Swift
I have been reading about the potential auto layout issues with preferred width settings. I currently have them set to auto layout and the label itself is set to a width of 560. I've added a constraint to keep the label 20 pixels from the trailing superview and while I thought this would work I still cannot get the text to wrap. The dimension settings are below.
Can someone explain how to get the text to wrap?
First, the good news: You have set the label to 2 lines and Word Wrap. So it can wrap. Excellent.
Now you must make sure the label is tall enough. Either give it no height constraint, or give it a big enough height constraint that it can accommodate two lines.
Finally, you must limit its width. This is what causes the text to wrap. If you don't limit the label's width, it will just keep growing rightward, potentially continuing off the screen. The limit on the label's width stops this rightward growth and causes the text to wrap (and the label to grow downward instead).
You can limit width in several ways. You can have an actual width constraints. Or you can have a leading constraint and a trailing constraint, to something relatively immovable, such as the superview. And there is a third way: on the Size inspector (which you do also show, at the bottom right of your question), set the Preferred Width (it is shown at the top of the Size inspector): this is the width at which, all other things being equal, the label will stop growing to the right and wrap and grow down instead.
Declare your UILabel programmatically and give
yourUILabel.contentMode = .scaleToFill
yourUILabel.numberOfLines = 0
yourUILabel.leadingMargin(pixel: 10)
yourUILabel.trailingMargin(pixel: 10)
This worked for me.
Your text will wrap if you have provided lines number more than 1. However you may not be able to see it wrap if the label height is not enough to show the content. I suggest you to remove the height constraint or increase its value.
In case this helps anybody: I had followed the advice given here to fix my label not wrapping to two lines but nothing worked. What worked for me was I first deleted some of the relevant constraints in storyboard (I'm using auto layout) and saw that the label wrapped properly. I slowly added back the constraints I needed and everything still seems to work fine. So deleting and remaking your constraints may help.
What fixed this problem was changing the label type to "Placeholder" under Intrinsic Size in IB. When I changed this the text wrapped and the warnings went away.
As I see you interface builder. There are two problems. First one is with your constraints, and another one is with the property.
You gave it a fixed height which is wrong while line wrap. You need to make the auto-resizing label, i.e. remove height and add the bottom constraint or simple remove height depend on your situation. Your text is moving to the next line, but due to fixed constraint, you can't see it.
You enable the option to clip subviews which is wrong as it cuts your view and you are unable to view wrap word.
Add a new case:
DO NOT add constraints to your label with a TEXTVIEW, or the label will expand to right without limitation.
In my case i set my parent stackview alignment from center to fill and set UILabel to
label.textAlignment = NSTextAlignment.right
