I want to set a UINavigationItem's title such that it displays a 2 line title with both lines in a smaller font than normal. I've definitely seen this effect on other apps such as Mail, but I can't figure out how to get it to work.

I tried setting a prompt, that's definitely not what I want, I want the Nav Bar to stay the same height but have the text get smaller and allow two lines.

Is this possible by default or do I need my own custom view to achieve it?
