How to use UISearchBar with tableView that has sections - iphone

Question

Ok so I am working on implementing a UISearchBar on a tableView that has sections. This may be wrong, but to populate the table view the first time, I have an array with lots of entries, and then populate the sections like this:
if(indexPath.section ==0){
[cell.textLabel setText:[tableData objectAtIndex:indexPath.row]];
}else if(indexPath.section ==1){
[cell.textLabel setText:[tableData objectAtIndex:indexPath.row+4]];
}else if(indexPath.section ==2){
[cell.textLabel setText:[tableData objectAtIndex:indexPath.row+8]];
}
Which is far from elegant, but it works. Now I am trying to hookup the UISearchBar, and this is the method that I am running into issues with:
- (void)searchBar:(UISearchBar *)sBar textDidChange:(NSString *)searchText
{
[tableData removeAllObjects];// remove all data that belongs to previous search
if([searchText isEqualToString:#""] || searchText==nil){
[tableView reloadData];
return;
}
NSInteger counter = 0;
for(NSString *name in dataSource)
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];
NSRange r = [name rangeOfString:searchText];
if(r.location != NSNotFound)
{
[tableData addObject:name];
}
[pool release];
}
[tableView reloadData];
}
So I am making an array again of entries that fit the search criteria, but then when I am trying to reload my tableView, it gets all bungled up because it is expecting sections. But all I want is the results in just a plain section-less tableView.
How can I implement this UISearchBar with a tableView with sections?
Thanks

Answer 1

set a BOOL when you enter search and adjust your section count accordingly
e.g.
in viewDidLoad
BOOL isSearching = NO;
set to YES when you enter the textDidChange method.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
int t;
if (isSearching) t = 1
else {
t= array.count;
}
return t;
}

You don't need to keep another variable around; just interrogate the tableView argument to see who is asking for the number of sections. For example, suppose your data is available in a fetchedResultsController:
if (tableView == self.searchDisplayDisplayController.searchResultsTableView) {
// your table is the search results table, so just return 1
return 1;
} else {
// your table is your "own" table
return [[self.fetchedResultsController sections] count];
}
I do the same thing in many of my table view delegate and data source methods.
