Question

I have created an application with a modal view that I can display and then dismiss. Is there an easy way to know when the modal view has been dismissed? I would like to reload the data in a table once the modal view has been dismissed and don’t know the best way of doing this.

Thanks

UIViewController has a property called parentViewController. In the case that a view controller is presented modally, the parentViewController property points to the view controller that presented the modal view controller.

In your modal view controller, in viewWillDisappear: you can send a message to the parentViewController to perform any action you wish, essentially.

Something like:

- (void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    [self.parentViewController doSomething];
}

If your parent view controller is a table view controller, then you should be able to call [self.parentViewController.tableView reloadData]; to do what you’re trying to achieve.
