Dragging onto the exit of the viewcontroller not working

Question

I have looked for this problem everywhere. I know how the unwind scene works. I have implemented the following code in the A VC

-(IBAction)returned:(UIStory         


        

Answer 1

To make Exit outlet active, add this code to viewController. Now you should be able to ctrl-drag to exit outlet. It is actually quite odd, that there should be empty method to make it work.

swift
@IBAction func unwindSegue(unwindSegue:UIStoryboardSegue) 

objC
- (IBAction)unwindSegue:(UIStoryboardSegue *)sender;
