title: I have an iPad app that keeps getting Terminating app due to uncaught exception 'NSInternalInconsistencyException'
body: <p>The first button displays a list of presidents and when you click on them you get their wikipedia page.  All worked well until I put in another button that let you change the language of the page from English to German, etc.  I keep getting this error in the debugger: </p>
  
  <p>Assertion failure in -[UITableView _createPreparedCellForGlobalRow:withIndexPath:], /SourceCache/UIKit_Sim/UIKit-1914.84/UITableView.m:6061
  2012-04-30 17:30:01.293 Presidents[11151:f803] <strong>* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:'
  *</strong> First throw call stack:</p>
  
  <p>I'm going through a book tutorial and I think once again they are missing code. Any ideas would be awesome!</p>
  
  <p>EDIT: Noob move on me guys I pasted the wrong code section: This new section is a custom popover that I added after the BIDMasterViewController, which was working fine.  This new section is where the problems arrived:</p>
