Save and Load UISwitch state in TableView

I want to save the switch state. I created custom cell class witch print one Switch on label but there is problem that if i search some text then Table View reload and my selected switch State is going to change, Is it possible to Maintain that state ?

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
  ....
selectionStyle = UITableViewCellSelectionStyleNone;
CfResultFatch *temp = [result objectAtIndex:indexPath.row];
NSLog(@"%@",temp.complanName);
//[cell.switchOnOff setOn:NO];
[cell.switchOnOff setTag:indexPath.row];
[cell.switchOnOff addTarget:self action:@selector(selectUser:)forControlEvents:UIControlEventValueChanged];
[cell.switchOnOff setTag:indexPath.row];
cell.lblUserName.text = temp.complanName;
cell.textFld.text = temp.cipd;
return cell;
}

//selectUser which is call when switch state change

-(IBAction)selectUser:(UISwitch*)sender{
if(sender.on)
{
    [selectedpet addObject:[result objectAtIndex:sender.tag]];
}else{
    NSLog(@"%@",sender);
    for(int j=0;j<[selectedpet count]; j++)
                   {
                       CfResultFatch *temp = [result objectAtIndex:sender.tag];
                       CfResultFatch *temp1= [selectedpet objectAtIndex:j];
                       if([(temp.complanName)isEqualToString:(temp1.complanName)]) {
                      [selectedpet removeObjectAtIndex:j];
          }
    }
  }
}

//and Search in searchBar this methode is call when search some text and the data is change from data base problem is here is i select 0 and 1 index switch on and then search some text, the new data in table view come with 0 and 1 index ON,how to maintain it and how to get my previous state of Switch

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText{
 NSString *weburl = [NSString stringWithFormat:@"%@%@", @"http://192.168.1.196/ravi/searchUser.php?mname=",searchText];
 NSURL *url = [NSURL URLWithString:weburl];
 NSData *data =[NSData dataWithContentsOfURL:url];
 [self getData:data];
 [temptab reloadData];
}

And ya. sorry for my poor english

You should store the state of the UISwitch when it is changed. It might not be the best way to do this, but you could store the states in a dictionary like this:

NSMutableDictionary *states = [NSMutableDictionary alloc] init];
[states setObject:[NSNumber numberWithBool:sender.on] forKey:[NSNumber numberWithInt:sender.tag]]

Then, when showing the UITableViewCell:

if ([states objectForKey:[NSNumber numberWithInt:indexPath.row]] != nil)
    cell.switchOnOff.on = [[states objectForKey:[NSNumber numberWithInt:indexPath.row]] boolValue]
else
    cell.switchOnOff.on = NO;
