Question

When converting a project to use ARC what does “switch case is in protected scope” mean?
I am converting a project to use ARC, using Xcode 4 Edit -> Refactor -> Convert to Objective-C ARC…
One of the errors I get is “switch case is in protected scope” on “some” of the switches in a switch case.

Edit,
Here is the code:

the ERROR is marked on the “default” case:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"";
    UITableViewCell *cell ;
    switch (tableView.tag) {
        case 1:
            CellIdentifier = @"CellAuthor";
            cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
            if (cell == nil) {
                cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        }
        cell.textLabel.text = [[prefQueries objectAtIndex:[indexPath row]] valueForKey:@"queryString"];
        break;
    case 2:
        CellIdentifier = @"CellJournal";
        cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        }
        cell.textLabel.text = [[prefJournals objectAtIndex:[indexPath row]] valueForKey:@"name"];

        NSData * icon = [[prefJournals objectAtIndex:[indexPath row]] valueForKey:@"icon"];
        if (!icon) {
            icon = UIImagePNGRepresentation([UIImage imageNamed:@"blank72"]);
        }
        cell.imageView.image = [UIImage imageWithData:icon];

        break;

    default:
        CellIdentifier = @"Cell";
        cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
        if (cell == nil) {
            initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
            cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
            }
        break;
    }


    return cell;
}

Surround each case itself with braces {}. That should fix the issue (it did for me in one of my projects).
