title: Reload TableView Tab Bar Application
body: <p>I have a tab bar application that displays tableviews in two of the tabs. The tableviews are populated using NSFileManager to read the contents of a plist file stored with user data. One of the tabs displays the "complete" items, the other tab displays the "Incomplete" items. As the user selects a row, a page with the details of the item selected is displayed. In the incomplete table there is a button the user can press to move these details from the "Incomplete" table to a "Completed" table. The plist is then updated using NSFileManager to change a field detailing if the item is in the complete or the incomplete list for this item.</p>
  
  <p>The problem I have is that the changes are not updated on the two tables just by selecting between the two tabs. The user has to quit the application and start it up again to see the item moved from one table to the other.</p>
  
  <p>The data seems to be updated its just the view that doesn't update.</p>
  
  <p>I'm new to cocoa so any help at all would be greatly appreciated.</p>
