Autolayout and Table View Header
What’s the best way to handle this situation?
I have a view that contains a 1) UIImageView and 2) UILabel (multi-line).
I set constraints appropriately. I do not specify a width or height for the image view or label, because intrinsicContentSize + constraints should combine to do the right things.
I create a UITableViewHeaderFooterView and I add this view to its contentView.
And… it’s all messed up.
It appears that I need to know the height of the view and sets its frame before adding it to the contentView.
How do I found out the best height for my view? Given the width (width of the superview), I need to know the best-fit height for my view.
Update 3:25 pm: I created a gist that shows my code.
Update 3:40 pm: Here’s what I expected. Create a view with subviews. Set constraints. Height is calculated from constraints. Everything works.
This reminds me of the old 45-minute rule for CSS-based layout. If it takes more than 45 minutes, punt and just use a table. Since it’s been about two hours, I’m overdue.
The old-fashioned way isn’t that hard, after all, especially given that I’ve done it a zillion times. Override layoutSubviews. Override sizeThatFits. Measure the text. Not rocket science. I would have been done two hours ago. (And it would be less code.)
But it still bugs me. I think that’s part of my anxiety with UI programming — I can master it, but then there are new, better ways of doing things, and those take time to master. Sometimes a lot of time. But I’ve got software to ship.
I don’t feel good about punting. But at least I learned some things, which is progress.
