how to add searchbar in uitableview?

I have an

displayed in a
, and I have added some elements there.

For example, element names are First, FirstTwo, Second, SecondTwo, Third, ThirdTwo.

Now I want to add a search bar in the screen. In that search bar when I type F, the table should only show First and FirstTwo.

How should I do this?


The best way to get the hang of this is by following a tutorial over here over here. The part you are looking for, is this:

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
   [tableData removeAllObjects];// remove all data that belongs to previous search
   if([searchText isEqualToString:@""]searchText==nil){
      [myTableView reloadData];

   NSInteger counter = 0;
   for(NSString *name in dataSource)
      NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init];
      NSRange r = [name rangeOfString:searchText];
      if(r.location != NSNotFound)
         if(r.location== 0)//that is we are checking only the start of the names.
            [tableData addObject:name];

      [pool release];


   [myTableView reloadData];
