Question

Scenario

The structure that I am having for my project is

A---B---C---D---E

A is the root view and I am in E

After doing some transactions successfully, I am doing

- (void) successfulToDoTransaction: {
    [self.navigationController popToRootViewControllerAnimated:YES];
}

This will take me back at A controller and in A I would like to display some info that has been done successfully in E.

Goal :

What is the best way to tell view controller A reload so that it can get the latest info… I am thinking about using notification like below (pseudo code ) but not so sure this is the best way to do that…

Please advice if you have any ideas about this one.

Answer 1

You could always add in your -(void)viewDidAppear method to reload content. If that’s not the route you want to take then use an NSNotificationCenter and addObserver in view controller A and postNotification in view controller E.
