Auto Layout to dynamically size uilabel width

Question

So I have two UILabels side by side in Storyboard. The second label should butt up against the right edge of the first one (trailing constraint of 1), but I also need the fi

Answer 1

1. Create the 1 point horizontal space between the labels: Control-drag from label2 to label1. Choose Horizontal Spacing from the pop-up. Double click the constraint. Change the constant to 1.
2. Give label1 a max width: Select label1. Go to the top menu bar, select Editor > Pin > Width. Double click the constraint. Change the relationship to <= and change the constant to the max width.
3. Vertically align the labels: Select both labels. Go to the top menu bar, select Editor > Align > Vertical Centers.
4. You still need to set constraints that define how your labels are positioned in their container view. I leave that up to you. I pinned label1 32 points from the left edge of the root view and 34 points from top layout guide.
5. Update the frames of the labels so they reflect the above constraints: Go to the menu bar in the lower right-hand corner of the canvas. Tap the "Resolve Auto Layout Issues" Tie-Fighter button. Select "Update All Frames…" in the pop-up.

Note: Notice that I did not have to create constraints to make label1's width reflect its content size. The content sizing constraints are generated automatically.
