使用约束基于内部视图高度设置UIView高度

Question

I have one UIView and inside that, N UILabels which are laid out relative to each other.

The containing UIView has a background color, I want to extend the UIView to be high enough to cover all labels inside it, so the background color is behind them all.

(I'm embedding them in a UIView so I can have the labels inset from the view edges.)

Is there away to make the UIView 's height expand to fill its content? I can't figure it from the constraint options, it seems like its all relative to superviews.

Normally I'd just work out the frame sizes programatically in viewDidAppear but those are getting reset by the constraints system, AFAIK.

Answer 1

I think I actually worked it out though.

I had the labels height set manually from when I drag-dropped and resized it. Deleting the height constraint on the UILabel made it size to fit content, which causes its superview to resize too. At least I think that's the case, I'm new to constraints.

Will leave the question up since it will probably bite someone else too.
