Line Break when press Return Key

[luuislipee]

Hello guys,

I'm new on this iOS programming thing, so I have a question that might sound stupid.. hahahaha
Anyway...
I'm writing an app for Music Writers, and my idea, is when the user hit 'Return', it adds a line break. I mean, Not the line just below that was written, but one more below.. Leaving a blank line between then... Or maybe two lines..
I'm using a UITextView.. So, how can I do this?

Thank you very much!
