What is the difference between lineHeight and leading?

I understand that, in ye olden days of typesetting, 'leading' was the total height of the lead blocks used for the letters - i.e. the height of the lines.

So, in my UITextView, what is the differe开发者_如何学运维nce between textView.font.leading and textView.font.lineHeight? Both return the same values in NSLogs in the fonts I've tried.

(Extra info - I need this because I'm programatically creating a 'lined notepaper' effect, and I need the line height to change depending on the font size).
