Differing Table View Heights

So I'm creating an app which I wanted different themes for the Table View. I've created two Prototype Cells and given them different CellIdentifiers. This is then stored in a plist of DefaultPreferences.

Even though I'd given them different heights in IB but this wasn't reflected in the app.

TableViewController.m

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *cellIdentifier = [[NSUserDefaults standardUserDefaults] stringForKey:@"Theme"];
    UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    return cell.bounds.size.height;
}

Then once you've made your choice and you return to the List you'll want to reload the data.

-(void)viewWillAppear:(BOOL)animated {
    [self.tableView reloadData];
}
