Inside of that function I said to put a break point if the break point is being hit you need to make sure you return an UITableViewCell to represent the searched XML.
Ex.
Code:
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"cell"];
if(!cell) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"cell"] autorelease];
//the myXML valuesForSearch is not a real method. It represents something you will
//have to do get an array of values from the XML for the passed string. I assume you
//will return an array and get the appropiate object using indexPath.row
cell.text = [[myXML valuesForSearch:passedString] objectAtIndex:indexPath.row];
return cell;
I hope that helps
