title: how to update data in tableView?
body: <p>I initialize data in my table with an array in <code>viewDidLoad</code> and then add the data to the cell. This a standard way of doing it that I read in a book.
  This is what I have:</p>
  
  <pre><code>- (void)viewDidLoad {
      [super viewDidLoad];
      //Create array and add data ("tableViewValues" is initialized in .h file)
      tableViewValues = [[NSMutableArray alloc]init];
      [tableViewValues addObject:@"$280,000.00"];
      [tableViewValues addObject:@"$279,318.79"];
  }
  
  // Customize the appearance of table view cells.
  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
  
      static NSString *CellIdentifier = @"Cell";
  
      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
      if (cell == nil) {
          cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
      }
  
      NSString *cellValue = [tableViewValues objectAtIndex:indexPath.row];
  
      cell.textLabel.text = cellValue;
  
      return cell;
  }
  </code></pre>
  
  <p>So when the view loads, those two currency values are in my table.
  Now in another function, I populate a another array with different currency numbers depending on what the user enter in a textfield. How would I update my current table view and replace those values with the values in my other array? Can anyone help me? Thanks!</p>
