What is -[NSString sizeWithFont:forWidth:lineBreakMode:] good for?

Question

In my question \"How do I get -[NSString sizeWithFont:forWidth:lineBreakMode:] to work?\", I learned that -[NSString sizeWithFont:constrainedToSize:lineBreakMode:]

It sounds like it would be good for single line labels. For example, if you're drawing a string that may be truncated or have a line break, but you won't actually draw more than one line. It could still be helpful to know the exact height and width of the string, so you can position it exactly where you want it (and draw other UI items around it).
