**Background**

I am making a vertical label to use with traditional Mongolian script. Before I was just rotating a `UILabel` but there were some performance issues and other complications with this. Now I am working on making a label from scratch. However, I need the vertical label to tell auto layout when its height adjusts (based on string length).

**What I have read**

I read the [Intrinsic Content Size][1] and [Views with Intrinsic Content Size][2] documentation. These were more about how to use it, though, and not how to define it in a custom view.

Searching for &quot;ios intrinsic content size for a custom view&quot; only gives me 

- https://stackoverflow.com/questions/24127032/proper-usage-of-intrinsiccontentsize-and-sizethatfits-on-uiview-subclass-with-a

in Stack Overflow. This particular question didn&#39;t even need intrinsic content size because their view was just an assembly of standard views.

**What I am trying**

What I am trying is my answer below. I am adding this Q&amp;A pair so that it won&#39;t take other people as long to find the answer as it took me with the search keywords that I used.
