UITableView delgate not called when UIViewController is popped
// If you can include some code it would help as I am a bit uncertain
// about exactly what you are trying to do from the question but
// you should use whichever of these is correct for project:

- (void)viewDidLoad {
    [super viewDidLoad];
    [myTable reloadData];
}

- (void)viewDidUnload {
    [myTable reloadData];
}

- (void)viewWillAppear {
    [super viewWillAppear];
    [myTable reloadData];
}

- (void)viewWillDisappear {
    [super viewWillDisappear];
    [myTable reloadData];
}
