    <p>I have a tableView that refreshes with data from an array via the textDidChange function for UISearchBar. The data is correct, but it does not appear in the tableView until after hitting an additional character (so, for instance, if i typed 'Boise' into the search bar, nothing happens, but 'Boise1' will load two cities named 'Boise'..so it's one step behind).</p> <pre><code>- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText { //---if there is something to search for--- if ([searchText length] &gt; 0) { NSLog(@"greater than 0!"); isSearchOn = YES; canSelectRow = YES; self.tableView.scrollEnabled = YES; [self performSelector:@selector(someMethod) withObject:nil afterDelay:0]; //[NSThread detachNewThreadSelector:@selector(matchSearchText) // toTarget:self withObject:nil]; //[self matchSearchText]; } else { //---nothing to search--- isSearchOn = NO; canSelectRow = NO; self.tableView.scrollEnabled = NO; } } </code></pre> <p>and in the method that is called:</p> <pre><code> - (void) someMethod { NSLog(@"-------------"); NSLog(@"some Method whut!"); CityLookup *cityLookup = [[CityLookup alloc] findCity:searchBar.text]; // clear array [tableCities removeAllObjects]; if ([cityLookup.citiesList count] &gt; 0) { tableCities = cityLookup.citiesList; int size = [tableCities count]; NSLog(@"there are %d objects in the array", size); } [cityLookup release]; [self.tableView performSelectorOnMainThread:@selector(reloadData) withObject:tableCities waitUntilDone:YES]; } </code></pre> <p>and finally the cellForRowAtIndexPath:</p> <pre><code>-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { int size = [tableCities count]; NSLog(@"there are %d objects in the array NOW", size); static NSString *kCellID = @"cellID"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCellID]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:kCellID] autorelease]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; } NSString *cellValue = [tableCities objectAtIndex:indexPath.row]; cell.textLabel.text = cellValue; return cell; } </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
