  1. POWhy doesn't my search table view appear when beginning search?
    text
    copied!<p>I've wired a UISearchDisplayController into my app along with a search bar. I've initialized it as so:</p> <pre><code>self.filteredObjectArray = [NSMutableArray arrayWithCapacity:[self.objectArray count]]; UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 43)]; searchBar.delegate = self; [self.view addSubview:searchBar]; UISearchDisplayController *searchDisplay = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self]; searchDisplay.delegate = self; searchDisplay.searchResultsTableView.delegate = self; searchDisplay.searchResultsDataSource = self; searchDisplay.searchResultsDelegate = self; </code></pre> <p>Which is pretty much the way I've seen it in other examples. I've also implemented the appropriate delegate methods, with the important filterContentForSearchText and the shouldReload* methods shown below:</p> <pre><code>- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope { [self.filteredObjectArray removeAllObjects]; // First clear the filtered array. for (XRay *xray in objectArray) { NSString *combinedLabel = [self combinedLabel:xray]; if ([combinedLabel rangeOfString:searchText options:(NSCaseInsensitiveSearch)].location != NSNotFound) { [self.filteredObjectArray addObject:xray]; } } } - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString { [self filterContentForSearchText:searchString scope: [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:[self.searchDisplayController.searchBar selectedScopeButtonIndex]]]; return YES; } - (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchScope:(NSInteger)searchOption { [self filterContentForSearchText:self.searchDisplayController.searchBar.text scope: [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:searchOption]]; return YES; } </code></pre> <p>However my search is not working when I give the search text box focus or input any characters. You'll also notice that the greyed out view does not appear over my regular table view.</p> <p><img src="https://i.stack.imgur.com/t1Iwe.jpg" alt="Screenshot"></p> <p><strong>EDIT</strong> cellForRowAtIndexPath</p> <pre><code>- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"XraySearchChoice"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } XRay *xray = nil; if (tableView == self.searchDisplayController.searchResultsTableView) { xray = [self.filteredObjectArray objectAtIndex:indexPath.row]; } else { xray = [self.objectArray objectAtIndex:indexPath.row]; } cell.textLabel.text = [self combinedLabel:xray]; return cell; } </code></pre>
