Adding Friends by Tapping on a Table View Cell - Build a Self-Destructing Message iPhone App

I've just finished the Adding Friends by Tapping on a Table View Cell video and when running the app in the simulator, tapping on friends highlights the cell, but it does not deselect itself nor does it add the checkmark until AFTER I select a different cell. I've looked over my code and as far as I can tell, it matches what is in the video:

- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [self.tableView deselectRowAtIndexPath:indexPath animated:NO];

    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    cell.accessoryType = UITableViewCellAccessoryCheckmark;

    PFRelation *friendsRelation = [self.currentUser relationforKey:@"friendsRelation"];
    PFUser *user = [self.allUsers objectAtIndex:indexPath.row];
    [friendsRelation addObject:user];
    [self.currentUser saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (error) {
            NSLog(@"Error: %@ %@", error, error.userInfo);
        }
    }];
}

Any insight on what's going on? I'm using Xcode 5.0.2 and targeting iOS7.

D'oh! Figured out my mistake. I used did*DeselectRowAtIndexPath instead of didSelect*RowAtIndexPath

The perils of autocomplete! I have made that same mistake before. :)

Fantastic! I was wondering why this wasn't working. Maybe a text-popup added to the video could prevent this. I could have sworn i saw the Deselect version of the method in the video
