title: table view is not pushing to the new view when cell is touched
body: <p>I'm trying to navigate from a table view, to anther UIViewController. I control-dragged my TableCell in the new UIViewController. Then I typed in the following code.</p>
  
  <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
  
  
      static NSString *CellIdentifier = @"Cell";
      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
      // Configure the cell...
      if (cell == nil) {
          cell = [[ UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
      }
      if ([indexPath section] == 0) {
          Tips *tipy = [arr objectAtIndex:indexPath.row];
          cell.textLabel.text = [tipy tipdescription];
          cell.detailTextLabel.text = [tipy.tipnumber stringValue];
          NSString *imagefile = [[ NSBundle mainBundle] pathForResource:@"unlikeico" ofType:@"png"];
          UIImage *image = [[UIImage alloc] initWithContentsOfFile:imagefile];
          [[cell imageView]setImage:image];
          cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
              } else {
                  Tips *tipy = [arr2 objectAtIndex:indexPath.row];
                  cell.textLabel.text = [tipy tipdescription];
                  cell.detailTextLabel.text = [tipy.tipnumber stringValue];
                  NSString *imagefile = [[ NSBundle mainBundle] pathForResource:@"likeico" ofType:@"png"];
                  UIImage *image = [[UIImage alloc] initWithContentsOfFile:imagefile];
                  [[cell imageView]setImage:image];
                  cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
                      }
  
      return cell;
  }
  
  
  - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
      if ([segue.identifier isEqualToString:@"showtext"]) {
  
          DisplayViewController *dvc = [segue destinationViewController];
          NSIndexPath *path = [self.tableView indexPathForSelectedRow];
          Tips *tipy = [arr2 objectAtIndex:[path row]];  
          [dvc setCurrenttext:tipy];
      }
  
  }
  </code></pre>
  
  <p>The table will display the data, but does not move to the new UIViewController. Xcode does not show any warnings or errors. What's the problem here?</p>
