I want to do something when user segues back in a navigation controller(iOS)

Question

I have a table view here and want to update the UI when user hit the 'back' button in a navigation controller. How can I do that?

Answer 1

There are lots of avenues to accomplish something like this.

• Implement viewWillDisappear
• Implement viewWillAppear
• Set up a delegate for your navigation and respond to changes
• Make your own back button that links to your own function
• Use an NSNotification when moving back

Anyone of the above is a good starting place.

Have you tried something like this ?

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [[self tableView] reloadData];
}
