title: in rubymotion how to manually invoke table method
body: <p>I'm using a UICollectionViewController and I'm trying to set an item as selected automatically (ie. previously selected options). If I attempt to set when I'm setting the cells data</p>
  
  <pre><code>def collectionView(view, cellForItemAtIndexPath: index_path)  
  
    //create the cell etc.. then
    cell.selected = true
    cell.update(index_path.row)
  end
  </code></pre>
  
  <p>I get NoMethodError for selected. However this works from the normal select/deselect methods.</p>
  
  <pre><code>  def collectionView(view, didSelectItemAtIndexPath: index_path)
    cell = view.cellForItemAtIndexPath(index_path)
    cell.selected = true     
  end
  </code></pre>
  
  <p>Any ideas on how can I automatically preselect a cell?</p>
  
  <p>Thanks,</p>
