title: Objective C access variable from different view controller
body: <p>I am using a utility application in storyboard. I also created a third viewcontroller, which is accessed through a segue from the flipsideviewcontroller. I want to add a value in the third viewcontroller to an NSMutableArray that exists in the mainviewcontroller. I have played around with "delegation", but I have not been able to get it to work. My question is, how do I access my array that is defined in the mainviewcontroller from the third viewcontroller? Thanks.</p>
