How to limit the length of text for labels?

This could开发者_运维技巧 be really easy but I it's not obvious when I google it.

I have few NSMenuItem items that get populated at runtime and the label can be very long.How do set a limit for the title with the "..." in the middle of the text?

You could write your own method to preprocess the text before it is set to the label, and adds in ... on your own terms.

Another possibility: grab the NSMenuItemCell from the menu item and set its line break mode to NSLineBreakByTruncatingMiddle
