Here's a quick sample code to check out: iPhoneCoreDataRecipes
On topic, here is one of the sweetest provided methods:
// If I want to delete the next 3 cells after the one you click
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSMutableArray* indexPaths = [NSMutableArray array];
for (int i = indexPath.row + 3; i < indexPath.row + 3; i++)
{
[indexPaths addObject:[NSIndexPath indexPathForRow:i inSection:0]];
}
[tableView beginUpdates];
[tableView deleteRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationFade];
[tableView endUpdates];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
I ran into this problem, if I understand you properly, that updating doesn't remove cells. So just remove them and then call update. Good luck!
