How can I make deleteRowsAtIndexPaths: work with GenericTableViewController?

Question

I\'m using Matt Gallagher\'s GenericTableViewController idea for controlling my UITableViews. My datasource is a NSFetchedResultsController

Well, bah. I just found this answer, which is not the same, but got me headed in the right direction. I'll leave this here for anyone in the future having similar troubles.

The key is to wrap the deleteRowsAtIndexPaths with begin and end tags, and force the model to update within the same block, resulting in:

[tableView beginUpdates];
[self constructTableGroups];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath]
        withRowAnimation:UITableViewRowAnimationFade];
[tableView endUpdates];

This caused the issue to go away, and the animations to work just perfectly.
