IOS Container View VC rejects parent?

I have 3 view controllers. Controller A calls B. B is in the form of a container that contains C, the table view controller. How do I use the didSelectRowAtIndexPath method in C to reject both B and C and return to A?

I've tried this:

[self.navigationController.parentViewController dismissViewControllerAnimated:YES completion:nil];

      

        
        
        
      

    

[self.navigationController.parentViewController dismissViewControllerAnimated:YES completion:nil];

      

        
        
        
      

    

And this:

[self dismissViewControllerAnimated:YES completion:nil];

      

        
        
        
      

    

None of them work.
