UITableView disable swipe to delete, but still have delete in Edit mode?

I want something similar as the Alarm app, where you can't swipe delete the row, but you can still delete the row in Edit mode.

When commented out tableView:commitEditingStyle:forRowAtIndexPath:, I disabled the swipe to delete and still had Delete button in Edit mode, but what happens when I press the Delete button. What gets called?

Answer

Ok, it turns out to be quite easy. This is what I did to solve this:

Objective-C

- (UITableViewCellEditingStyle)tableView:(UITableView *)aTableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // Detemine if it's in editing mode
    if (self.tableView.editing)
    {
        return UITableViewCellEditingStyleDelete;
    }

    return UITableViewCellEditingStyleNone;
}

Swift 2

override func tableView(tableView: UITableView, editingStyleForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCellEditingStyle {
    if tableView.editing {
         return .Delete
    }

    return .None
}

Swift 3

override func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCellEditingStyle {
    if tableView.isEditing {
        return .delete
    }

    return .none
}

You still need to implement tableView:commitEditingStyle:forRowAtIndexPath: to commit the deletion.
