title: iOS: Adding row to tableview
body: <p>I have a tableview that is based on a array of DB results, these results contains a date field. I have a custom cell that contains an image and labels. I'm trying to do:</p>
  
  <p>At cellForRowAtIndexPath I verify if the date of current item (objectAtIndex:indexPath.row) has date field bigger than the last item (objectAtIndex:indexPath.row-1). If this is true: I want to add a cell filling the ImageView with a certain image, but I need to add a new row just for show this image.</p>
  
  <p>How can I do this? I'm already doing this verification, but I need to add a new cell...</p>
