The docs on boundingRectWithSize:options:context: say:
"Typically, the renderer preserves the width constraint and adjusts the
height constraint as needed."
Yes, that's what I was hoping for. But in fact I'm getting a much narrower
width than what I supplied.
I suspect that the problem here has to do with differing expectations as to
what "bounding rect" means, and as to what my paragraph margins mean. Here's
some more complete code:
NSString* sentence = @"This is a test. ";
NSString* s = @"";
for (int i = 0; i < 20; i++)
s = [s stringByAppendingString:sentence];
NSMutableParagraphStyle* mps = [NSMutableParagraphStyle new];
mps.headIndent = 20;
mps.firstLineHeadIndent = 20;
mps.tailIndent = -20;
NSAttributedString* as = [[NSAttributedString alloc] initWithString:s
attributes:@{
NSParagraphStyleAttributeName:mps
}];
CGRect r = [as boundingRectWithSize:CGSizeMake(100,10000)
options:NSStringDrawingUsesLineFragmentOrigin context:nil];
NSLog(@"%@", NSStringFromCGRect(r));
The resulting width is 51.8. So it looks as if that's the width *after* the
margins (20 and 20) have squeezed the text inward. What we're getting, it
seems, is the minimum bounding rect containing any text. But that's not what I
want to know; I want to know the height of this text as drawn within the width
I supplied (100) using the paragraph margins I supplied. Is there some other
way to find that out? Or is this a bug with regard to how margins are
interpreted? m.
