If you are using search bar. then You can search your contain of table view using delegate method of searchbar

(void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText
{
// myArray is main array for Table View
// tempMainArray which store myArray Data

myArray = [[NSMutableArray alloc]initWithArray:tempMainArray];
NSMutableArray *searchArray = [[NSMutableArray alloc]init];


[searchArray removeAllObjects];// remove all data that belongs to previous search
if([searchText isEqualToString:@""]|| searchText==nil){

    [myArray removeAllObjects];
    myArray =  tempMainArray;
    [_objTableView reloadData];

    return;
}

NSInteger counter = 0;
for(NSString *name in myArray)
{

    NSRange r = [name rangeOfString:searchText];
    if(r.location != NSNotFound)
    {
        if(r.location== 0)//that is we are checking only the start of the names dynamicaly.
        {
            [searchArray addObject:name];
        }
    }

    counter++;


}

if (searchArray.count > 0) {

    [myArray removeAllObjects];
     myArray =  searchArray;
    [_objTableView reloadData];
}
else
{
    [myArray removeAllObjects];
    myArray =  tempMainArray;
    [_objTableView reloadData];
}

}
