title: xcode/storyboard: can't drag bar button to toolbar at top
body: <p>I have a view controller that is the detail view of a table.  When you click on the row of the table it takes you to the detail view.  The detail view is embedded in a navigation controller such that there is a button at the upper left of the navigation bar that sends you back to the table.  So far so good.</p>
  
  <p>I now want to add an edit button to the right side of the navigation bar so that you can edit the detail view.  My plan is this will add another view controller modally that lets you edit the details of the item.  Standard stuff.</p>
  
  <p>However, when I try to drag a bar button item from the list of objects to the navigation bar, it won't take.  Instead, when I let go off the mouse button, it leaves the bar button on the tab bar controller at the bottom.  (My navigation scheme includes different tabs and for each tab a table, detail view etc.)</p>
  
  <p>Anyone run across this before and can suggest what I'm doing wrong or some sort of workaround to add the bar button item to the right side of the navigation screen.  Do I have to add it in code?</p>
  
  <p>Thanks for any suggestions.</p>
