Question

In my project I have tableView with 10 cells. And in didSelectRowAtIndexPath all cells have multiple ViewController (files) so, my didSelectRowAtIndexPath looks like

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

if(indexPath.row == 0) {

            CallViewController *viewc = [[CallViewController alloc] initWithNibName:@"CallViewController" bundle:nil];
            [self.navigationController pushViewController:viewc animated:YES];
        }else if(indexPath.row == 1) {
            BirthdayViewController *viewc = [[BirthdayViewController alloc] initWithNibName:@"BirthdayViewController" bundle:nil];
            [self.navigationController pushViewController:viewc animated:YES];
        }

so I don’t want these conditions
I want my code be clean

What is your underlying data model for tableview? If you could add additional attribute as ViewController Class Name you could do something like

- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDictionary *row = [rowData objectAtIndex:indexPath.row];
Class viewControllerClass =
    NSClassFromString([row objectForKey:@"viewControllerClassName"]);

//Default VC init looks for nib file named as VC afaik, if not, you could
    //add another attribute with init selector name
UIViewController *viewController =
    [[viewControllerClass alloc] init];
[self.navigationController pushViewController:viewController animated:YES];
}
