title: segue from table view cells that replace detail controller do not fire
body: <p>I am using a <code>UISplitViewController</code> for a master/detail app. The master controller presents a table view with different cells that when selected are to replace the detail view controller. When the cell is selected the corresponding replace segues do <em>not</em> fire. </p>
  
  <p>You can see in the images below I have a replace segue wired to the table view cell labeled "Province Name." </p>

  <p>The <code>tableView:didSelectRowAtIndexPath:</code> method is invoked, and I can programmatically generate the segue with <code>performSegueWithIdentifier:sender:</code>, but I should <em>not</em> have to do this! I use push segue's frequently from table-view cells with no problem. </p>
  
  <p>Interestingly enough, if I wire a replace segue to a <code>UIBarButtonItem</code> it works just fine (i.e., I do <em>not</em> have to programmatically perform the segue). The problem is particular to replace segues wired to table view cells. </p>
  
  <p>Is this a bug or is there something I am overlooking here?</p>
