How to make a Multi-line (2 lines) label truncate the last line (OS X)

Question

I'm trying to make a multi-line label with 2 lines truncate the last line only. But it seems that, if I choose the Layout of that label as Truncates, my multi-line label becomes one-line.

Here's what I want (I manually typed "..." for demonstration purposes):

Here's what I have when I set my label as Truncates in IB (as you can see it still has 2 lines but acts as if it was only 1):

Is this supposed to happen? If not, how can I achieve the truncate style of the first image?
Thanks!

Answer 1

It looks as though you must have Uses Single Line Mode checked, which should be unchecked. Also, under Layout is the Control section, which can be set to specify which part of the label to truncate and whether to clip, wrap, and which portion to truncate (head, middle, tail).
