There is another way to pass data between views including popViewControllerAnimated and it's with a global var instance, so If you modify that Var in your detail view and after do the popViewControllerAnimated, you can call the new data in the viewWillAppear method.

The first step is declare the Global var in main.h

NSMutableArray * layerList;

And now you have to call it in detail view.

SecondView.m

extern NSString *layerList;

SecondView.h

-(void)back{
    layerList = @"Value to send";
    [self.navigationController popViewControllerAnimated:YES];
}

Now you can use the information in the Master View after detect the pop action.

FirstView.m

extern NSString *layerList;

FirstView.h

-(void)viewWillAppear:(BOOL)animated{
   NSLog(@"This is what I received: %@",layerList);
}
