UIWebView: Sending data back to previous controller using unwind segues without button

Question

Say, for instance I have a UIWebview. If I get the status code of 404, then I want to return some data to the previous view controller so that it knows to refresh the list of webpages.

I heard about unwind segues. However, everything that I have found on this sounds like it has to be implemented via a storyboard button.

Is there anyway to perform an unwind segue just in code. Meaning if I find this error - then set some kind of variable to the previous view controller so that it knows how to handle the error?

Thanks!

I did do research before asking. But, my question was specifically without a button. Everything I had found was with a button. Thank you for the link! – Sandy D. Dec 08 '14 at 01:43
