title: xcode reloading tableview
body: <p>In my app I have a tableview being filled by values from an NSMutableArray. This mutable array is being added to in a separate viewcontroller, and so I have to reload the data. </p>
  
  <p>This is probably a very simple question, but I have reading 15+ posts and none of them seem to address xcode 4.2, and where exactly to put the [self.tableView reloadData]. Where exactly should this method be put? When I have tried putting it in various places in the tableviews source code, the tableview initialized for the first time with no values in it.</p>
  
  <p>Or should it be put in the other viewcontrollers code, in which case how can I reference the particular instance of my UItableview subclass that is being used?</p>
  
  <p>Thanks very much in advance.</p>
