Question

Noobie iOS developer with an adopted iOS app here.

I have a settings piece of an iOS app and when the user clicks done, I want the modal view controller (which it currently does) and I want to call a function called updateMainUI in the presentingViewController.

Here’s the method I am calling:

- (void)done:(id)sender
{
  [[self presentingViewController] dismissViewControllerAnimated:YES completion:nil]; // works 
  [[self presentingViewController updateMainUI]; //doesn't work

But I get the following error:

No visible @interface for 'UIViewController' declares the selector 'updateMainUI'

But I have declared this in the presenting controller

@interface LocationsViewController : UITableViewController <CLLocationManagerDelegate, UISearchBarDelegate, UISearchDisplayDelegate>
-(void)updateMainUI;

But it’s odd that the error should be about UIViewController when the presenting controller is a UITableViewController.

Any ideas on how to get the updateMainUI working? And what I’m doing wrong?

thx

edit #1
This is how I’m creating this – any idea how to get a refernce to the *nearbyViewController?

UIViewController *nearbyViewController = [[LocationsViewController alloc] initWithNearbyLocations];
UINavigationController *nearbyNavigationController = [[UINavigationController alloc] initWithRootViewController:nearbyViewController];
...
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = [NSArray arrayWithObjects:nearbyNavigationController, browseNavigationController, eventsNavigationController, nil];

After dismissing ones self, you should expect self.presentingViewController to become nil. Try calling updateMainUI just before dismissing.
