How do I refresh a table view from a separate uiviewcontroller?

Question

In my project I have two view controllers one that lists all the core data stored in a table view and a second that allows the user to input data to be stored. However when I click the back button on the navigation controller on the second it fails to refresh the tableView .

I have tried [self.tableView reloadData] in the viewDidLoad as a bit of a long shot but no joy.

How would i go about refreshing the data when the user clicks back?

Many thanks Danny

最短的路线是将[self.tableView reloadData]从viewDidLoad移到viewDidAppear但我建议使用委托或回调，以便仅在必要时重新加载。
