I am designing a very simple "Today" widget with just two elements: a text label (shown here with a red background) and an info button. I want the info button to always appear right after the label.
So:
the info button should always stick to the right margin
the label should always stick to the left margin
the label should resize itself so it is the full width of the available space, right up to the edge of the button
How can I do this?! Auto Layout is sooooo confusing and I've been playing with it for an hour with no luck. Can't figure out where to start. I think I need at least three constraints, one for each of the needs above...
Your info button will have a fixed width and height. Set its right margin to the parent right. Set your red label's left margin to parent left and right margin to info button's left.
Now since your red label doesn't have a width restriction, it will take all of the width between left margin and right margin.
This is how it looks.
You should create top, bottom, width and trailing (to the container view) constraint info button.
For the label, they should be leading, top, bottom (to the container view) and horizontal spacing to the info button.
Hope that will help.

I'm trying to recreate a custom table view cell in my xib file as shown below. The company's square image is on the left. The company's name and company's booth (2 UI Labels) are to the right of the company's image. The star button is to the right of the text and is a square image. I guesstimated that the company's image and favorites button should be about 8px from the top and edge.
I tried to create 4 constraints for the top, bottom, left, and right of every element (image, 2 UI labels, and button). I also added 1:1 aspect ratio constraint to the image and button to make sure the image would be square. Then I aligned the left edge of the 2 UI labels. I vertically centered the image and the button. However, it came out with no star button and the location and title switched. How do I create this design using constraints?
Their is no difficulty with that.
First if we talk about your left UIImageView, Set following constraints,
Leading constraint
Fixed Height
Fixed Width
Centre Vertically
After that the UIImageView on left, set following constraints,
Trailing space from superview
Fixed Height
Fixed Width
Centre Vertically
Now for both Labels, put them in a UIView and give that UIView following constraints,
Leading space from left image view.
trailing space from right image view.
top space from superview
bottom space from superview
Now for upper UILabel, Set following constraints,
Leading space
Trailing space
top space
Now for lower UILabel, Set following constraints,
Leading space
Trailing space
top space from upper UILabel
bottom space
After all this, i think that this will work for you.
You can use the constraints in the image below. It will work for all screen size and for any height of row.
How would I go about setting constraints for my price label to stay on the side of the screen? Below Is a picture of what I want my tableviews to look like on all iPhones.

It's easy to do:
1)first add left label
2)ctrl + drag the left label to cell content, and choose Center Vertically in Container:
3)Click Add New Constraints in the right bottom of interface builder,
deselect the Constraint to margins, and click the left dotted line and set the left margin value , eg:8
4) As the same to left label, you can set constraints to your right label, and the different is only you should set right margin nor left margin , in there I omit the Vertically in Container step of right label, you can see 2):
EDIT
as matt's advice, you better set the right label's alignment to right;
The blue label is on the right and needs to stay on the right. It is sized automatically by its content. So just pin its right edge to the right of its superview and its top or bottom (not both) to the top or bottom of its superview.
How would I go about creating a layout like this using autolayout?
The icon is UIImage, text is UILabel.
The label text can vary in width, but will always be single-line. How do I force the label to scale with the text horizontally and UIImage to be immediately to the left of the label?
I have tried using attributedText. I also tried views as containers and a horizontal stack view, but failed to get the result I wanted. What are the other options?
That should be absolutely no problem - just put in the image, make layout constraints to the left and top of the view, then add the label right to it, and make layout constraints between the right side of the image and the left side of the text.
To restrict the label width you can add a constraint from the right side of the label to the right side of the view, if you want to make the label as small as possible with a greater-than sign.
EDIT
If the whole should be bound to the right border of the superview, put both in a view, align the view to the right border of the superview, and make a constraint from the right side of the label to the right side of the view. The view will resize accordingly when the label resizes.
I went for a solution where I added a third view as the leftmost element in a horizontal stackview and set the stackview's distribution as 'equal centering'. It actually fit well with the rest of the planned layout (all elements are used efficiently). Thank you for your help guys.
I want to have 15 buttons equally spaced between them and correctly leading and trailing the superview vertically. I set constraints so that the left set of buttons aligns to the left margin and the right set aligns to the right margin. The first button leads from the top margin in each set, and the remaining buttons each have a constraint for vertical space set to the upper neighbor. I thought this would be enough to make it work but it wasn't. As you can see, for an iPhone 4, the number of buttons displayed on the screen is only 12 so I would definitely need to somehow dynamically change the button size depending on the screen size. I am attaching a screenshot from the storyboard that shows the Any x Any editor view and a preview for the 3.5-inch screen.
This was really easy to accomplish using stack views. Simply select all the buttons and click the leftmost icon (bottom right side of left pane) which is named Stack, and see the magic happening!
Try to set the constraints like this:
First select the all elements on left side and give leading constraint:
Now select first element and give top constraint:
Now select the second element and select it , and drag it to first element and give vertical spacing: , repeat giving vertical spacing for all the elements, So that each element will be vertical space constrained with its top element!!.
Do the same for elements on right side.
Give the trailing constraints for all elements on left,
and the select top element and give top constraint
and then select one element below top element and give vertical spacing between those two, repeat it for all the elements!!! So that each element will be vertical space constrained with its top element!!
Note: I only gave left constraints, you can try for right side too!!!!!
Add height constrain to the top left button to be 1/15 of the superview height and for all buttons let their height equal to the top left one.
Note it will work only if the vertical spacing is zero between buttons.
If you have a vertical space value for example x, then set it as 1/15 - 14 * x
Note #2 in iOS 9 only, seems the stack view will help perfectly in that
Using auto layout I am trying to create two buttons on the bottom like this
After dragging two buttons I set constraints like this
On Back button I set Leading Space to Container Margin and Bottom Space to Bottom Layout Guide
On Go To Settings button I set Trailing Space to Container Margin and Bottom Space to Bottom Layout Guide
Then I ctrl+Drag from Back button to Go To Settings button and set the Equal Widths constraint and I get this.
Then I update the Back button width same as Go To Settings button which is 101 and all constraints turn to blue.
But I want both buttons to cover half of the screen no matter what the size of screen is, same as shown in first screen shot, How to accomplish this?
you can done it using equal width to 2nd button like this
and the output is
Here is apple guide
You can have the equal widths constraint between the buttons, but you also have to tell them which is that width you need.
So drag from a button to the superview, add an equal widths constraint. Then in the properties of the constraint you've added, set the multiplier to 0.5, this way your buttons should be on half the screen.
You need to add one more constraint - set horizontal space between buttons to 0
You can followed the layout changes. you will get what you want.
Layout for Back button.
Layout for Go to Setting button.
