How do I forward data to a protocol before dismissing a view manually?
Question
I want to dismiss a view controller manually using dismissViewController:animated . The problem is I want to save a value before I dismiss the view, otherwise it becomes null and I get no data in my first view. Does anyone have any idea how to do this?
