title: How to add a search bar and search display to an rss feed in UItableview
body: <p>I created an RSS reader that parses from a .xml file. I am trying to create a search bar and search display controller, but am not sure how to search the objectForKey "title" or objectForKey "summary" within the UITableView.</p>
  
  <p>Any help would be greatly appreciated.</p>
  
  <p>The numberOfRowsInSection and cellForRowAtIndexPath looked like this:</p>
  
  <pre><code>- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
  {
      // Return the number of rows in the section.
      return self.parseResults.count;
  }
  
  - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
  {
      static NSString *CellIdentifier = @"Cell";
      UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
  
      //Check if cell is nil. If it is create a new instance of it
      if (cell == nil) {
          cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
      }
      // Configure titleLabel
      cell.textLabel.text = [[self.parseResults objectAtIndex:indexPath.row] objectForKey:@"title"];
      cell.textLabel.numberOfLines = 2;
      //Configure detailTitleLabel
       cell.detailTextLabel.text = [[self.parseResults objectAtIndex:indexPath.row] objectForKey:@"summary"];
  
      cell.detailTextLabel.numberOfLines = 2;
  
      //Set accessoryType
      cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
  
      //Set font and style
       cell.selectionStyle = UITableViewCellSelectionStyleGray;
       cell.textLabel.font = [UIFont boldSystemFontOfSize:14];
  
      return cell;
  }
  </code></pre>
  
  <p>I recently tried to follow this sample project - <a href="https://github.com/deepthit/TableViewSearch.git" rel="nofollow">https://github.com/deepthit/TableViewSearch.git</a> -  based on a suggestion.<br>
  My code then looked like this:</p>
  
  <pre><code>@interface QldRecentJudgmentsViewController () {
  
      __strong NSArray *mFilteredArray_;
      __strong UISearchBar *mSearchBar_;
      __strong UISearchDisplayController *mSearchDisplayController_;
  }
  
  @end
  
   @implementation ViewController
   @synthesize parseResults = _parseResults, HUD;
  
  
  - (void)viewDidLoad {
      [super viewDidLoad];
  
  
      mSearchBar_ = [[UISearchBar alloc] initWithFrame:CGRectMake(0,
                                                              0,
                                                              self.view.bounds.size.width,
                                                              44)];
  
       mSearchBar_.delegate = self;
       mSearchBar_.placeholder = @"search";
       self.tableView.tableHeaderView = mSearchBar_;
  
       mSearchDisplayController_ = [[UISearchDisplayController alloc] initWithSearchBar:mSearchBar_
                                                                contentsController:self];
       mSearchDisplayController_.searchResultsDelegate = self;
       mSearchDisplayController_.searchResultsDataSource = self;
       mSearchDisplayController_.delegate = self;
  
   }

  <p>However, when I follow this the RSS feed does not load anymore in the tableview, so there are no results. Nevertheless when I try to search it does not correctly search the "title" or "summary" and the search results do not appear correctly -the cells are not neatly aligned after searching for something and getting results. Also, the only way to see RSS in the tableview is to search for any generic string, but once you press cancel in the search bar the RSS feed disappears and shows an empty tableview.</p>
  
  <p>Thanks for any help in advance. </p>
