Well, this is dumb. All of my measurements were with the Simulator screen set
to scale by 75%, which by coincidence made the numbers work out for the height
of the content, and made the height of the view look wrong. It turns out the
situation is just the opposite: The views are in fact of the requested size,
but the Javascript I use to read the height reports too short by the height of
the last wrapped line. (Unless that, too, is a coincidence.)
This becomes a matter of HTML/Javascript, and therefore off-topic, but on the
chance the problem is obvious, I'll repeat the structure of my document's body,
and the method I'm using to measure it.
<body>
<div id="paragraphs">
<p></p>
<p></p>
<p></p>
</div>
</body>
- (CGFloat) preferredHeight
{
NSString * answer = [self.webView stringByEvaluatingJavaScriptFromString:
@"document.getElementById(\"paragraphs\").offsetHeight;"];
return answer.floatValue;
}
<body>
<div id="paragraphs">
<p></p>
<p></p>
<p></p>
</div>
</body>
