delegate method code:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
   selectedTransIdArray = [NSMutableArray arrayWithArray:userSession.transactionArray];   
NSLog(@"selectedTransIdArray first %@",selectedTransIdArray);

NSString *state = [dataTransArray objectAtIndex:indexPath.row];

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if(cell.accessoryType == UITableViewCellAccessoryNone)
{
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
    [selectedTransIdArray addObject:state];
    userSession.transactionArray = selectedTransIdArray;
}
else
{
    cell.accessoryType = UITableViewCellAccessoryNone;
    [selectedTransIdArray removeObject:state];
    userSession.transactionArray = selectedTransIdArray;
}

NSLog(@"selectedTransIdArray %@",selectedTransIdArray);
userSession.transactionArray = selectedTransIdArray;
[[NSUserDefaults standardUserDefaults] setObject:selectedTransIdArray forKey:@"aKey"];
[[NSUserDefaults standardUserDefaults] synchronize];

Answer 1

u have to write a algorithm which tell u that this row data is checked or not. and accordingly change value of checked objectatindex value

if (indexPath.row == checked){
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
} else {
    cell.accessoryType = UITableViewCellAccessoryNone;
}

I think the condition you are checking is not behaving as you expected. Checking for cell's accessory type is not working, instead can you check whether the state is present in selectedTransIdArray like this

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
   selectedTransIdArray = [NSMutableArray arrayWithArray:userSession.transactionArray];   
NSLog(@"selectedTransIdArray first %@",selectedTransIdArray);

NSString *state = [dataTransArray objectAtIndex:indexPath.row];

UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if(![selectedTransIdArray containsObject:state])
{
    cell.accessoryType = UITableViewCellAccessoryCheckmark;
    [selectedTransIdArray addObject:state];
}
else
{
    cell.accessoryType = UITableViewCellAccessoryNone;
    [selectedTransIdArray removeObject:state];
}

NSLog(@"selectedTransIdArray %@",selectedTransIdArray);
userSession.transactionArray = selectedTransIdArray;
[[NSUserDefaults standardUserDefaults] setObject:selectedTransIdArray forKey:@"aKey"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
