Filtering multiple arrays - xcode

Question

I am trying to filter 4 arrays but I can't make it work. This is a pushed tableview that uses NSString to populate. When I type something in the search bar, the search results are from 1 Array(MARLINS) even in the others. I know the problem is in -(void)filtertContentForSearchText:. What am I missing?
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection: (NSInteger)section
{
if (tableView == self.searchDisplayController.searchResultsTableView)
{
return [self.searchResults2 count];
}
else
{
if ([testName isEqualToString:#"CES"])
return [self.CES count];
if ([testName isEqualToString:#"MARLINS"])
return [self.MARLINS count];
if ([testName isEqualToString:#"DELTA 2, NAVIGATOR"])
return [self.DELTA count];
if ([testName isEqualToString:#"CREW 2002, NAVIGATOR"])
return [self.CREW count];
}
return 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifire = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifire];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifire];
}
if (tableView == self.searchDisplayController.searchResultsTableView)
{
cell.textLabel.text = [self.searchResults2 objectAtIndex:indexPath.row];
}
else
{
if ([testName isEqualToString:#"CES"]) {
cell.textLabel.text = [self.CES objectAtIndex:indexPath.row];
}
else if ([testName isEqualToString:#"MARLINS"]) {
cell.textLabel.text = [self.MARLINS objectAtIndex:indexPath.row];
}
else if ([testName isEqualToString:#"DELTA 2, NAVIGATOR"]) {
cell.textLabel.text = [self.DELTA objectAtIndex:indexPath.row];
}
else if ([testName isEqualToString:#"CREW 2002, NAVIGATOR"]) {
cell.textLabel.text = [self.CREW objectAtIndex:indexPath.row];
}
}
return cell;
}

self.searchResults2 = [ self.CES filteredArrayUsingPredicate:predicate];

self.searchResults2 = [ self.DELTA filteredArrayUsingPredicate:predicate];

(Extracting from comments into an 'answer', edited slightly to flow together better):
You have the scope parameter that you're not using inside the filter method. Pass in something useful there from shouldReloadTableForSearchString: to know which array you should be filtering.
Look at that scope variable. If its existing value is something you can use to identify which array you want to use, then at the bare minimum, you can replicate your if...else block similar to the code you have in cellForIndexPath and only filter a particular array.
