TOPIC: Reload DetailTableViewModel's cell accessories

Reload DetailTableViewModel's cell accessories 1 year, 7 months ago #1

Hi,

I have a UITableViewController on which I'm pushing various STV DetailTableViewModels. This subclass is the only class I have to render three or four DetailTableViewModels. That works great.

Now I need to reload the data (especially the accessoryView) of cells which sit in one of these DetailTableViewModel.
[self.tableView reloadData] doesn't help, because it seems that this only affects the cells from the root table view (self.tableView in a UITableViewController subclass), and not the DetailTableViewModels.

So, how do I reload these DetailTableViewModels?

Thanks,
Patrick

Hi Patrick,

If I understand you correctly here, all you need to do is call [myDetailTableViewModel.modeledTableView reloadData] . Please tell me if I am missing something here.

Hi Tarek,

I forgot to mention that I need to call that method in an method which is being called when the user switches the active tabBarItem (it's UITabBarControllDelegate's )tabBarController: didSelectViewController: method).

In this method I have no information about the current detailTableViewModel. How do I get the detailTableViewModel, which is currently being showed? As I mentioned, I have multiple detailTableViewModels.

Hi again Patrick,

I am sure there are many ways to do this, but here is what first comes to my mind:

1- Create a class called MyViewController which subclasses UITableViewController, then create an SCTableViewModel retain property called tableModel for example.

2- Have MyViewController as a superclass for all your view controllers and delete any tableModel member variables you already have (they will get that from their superclass).

3- 
 
- (void)tabBarController:(UITabBarController *)tabBarController 
  didSelectViewController:(UIViewController *)viewController
{
  [((MyViewController *)viewController).tableModel.modeledTableView reloadData];
}
 



Hope this helps.

Thanks, Tarek.

This works fine, even though I had to adjust the delegate method's code, because my UITabBarController is holding UINavigationControllers and not UIViewControllers. (Of course you couldn't know that. )

- (void)tabBarController:(UITabBarController *)tabBarController 
    didSelectViewController:(UIViewController *)viewController {
 
    if ([viewController isKindOfClass:[UINavigationController class]]) {
 
      UINavigationController *tempNavController = (UINavigationController *)viewController;
      SCTableViewController *tempTableViewController = (SCTableViewController *)tempNavController.topViewController;
 
      if ([tempTableViewController isKindOfClass:[SCTableViewController class]]) {
            [tempTableViewController.tableViewModel.modeledTableView reloadData];
      }
 
   }
}
