Question

In past, I followed a little tutorial to achieve a UISearchBar in my UITableView.

It was made of arrays. Now that I have .plist file which handles everything, how would the searchBar be?
I mean, I did something like:

 copyLists = [[NSMutableArray alloc] initWithArray:sortedList copyItems:YES];

Where sortedList is the array which contains the plist.

Basically the searchBar works fine, but when I type in a word, it doesn’t show any cells, even if I write the exact name of a cell.

Should it return the key name contained in the plist which is the name of the cell?

How would the searchBar change with plists?

Answer 1

- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
    [self.filteredList removeAllObjects]; // First clear the filtered array.

    NSArray *objcts = unfilteredList;

    for (NSDictionary *section in objcts)
    {
        for (NSDictionary *row in [section valueForKey:@"Rows"])
        {
            NSRange rng = [[row valueForKey:@"name"] rangeOfString:searchString options:(NSCaseInsensitiveSearch|NSDiacriticInsensitiveSearch)];

            if (rng.length != 0)
                [self.filteredList addObject:row];
        }
    }
    // Return YES to cause the search result table view to be reloaded.
    return YES;
}

make sure your Search Bar and Search Display Controller delegate are set right. Then for displaying the cell use:

NSArray *rows;
if (tableView == self.searchDisplayController.searchResultsTableView)
{
    rows = filteredList;
} else {
    NSDictionary *section = [unfilteredList objectAtIndex:indexPath.section];
    rows = [section objectForKey:@"Rows"];
}
cell.textLabel.text = [[rows objectAtIndex:indexPath.row] objectForKey:@"name"];

and change the logic for rowCount, titleHeader, etc.
