What code I have to write in didSelectRowAtIndexPath method for navigate/push to new ViewController, according to my example?

Question

I am referring project from GitHub.

I am trying to modify it according to my requirement, but I am not getting and not able to understand that what code I have to write in didSelectRowAtIndexPath method.

What I want is that after clicking tableView row it can level 0 or level 1 (here level 0 means - row has no sub child and level 1 means row has subview/child rows )

When I click on any tableView row either level 0 or level 1, it has to navigate to next viewController.

In this example, row number 2 and 3 are expandable i.e it contains level 1 rows, row 0, 1, 4 and 5 are level 1 rows they don't expand.

Here is project link (updated project link)

***** Added Code ****

the code I written in AppDelegate class,

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.


   userDefaults=[NSUserDefaults standardUserDefaults];
mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle: nil];


if ([[NSUserDefaults standardUserDefaults] boolForKey:@"loginSuccess"]) {
      NSLog(@"Login Done!!!");

      HomeViewController *homeVC=[mainStoryboard instantiateViewControllerWithIdentifier:@"homeId"];

      SampleNavigationController *navigation = [[SampleNavigationController alloc] initWithRootViewController:homeVC];

    //SWRevealViewController * vc= [[SWRevealViewController alloc]init];

    //ExpandableTableViewController *sidemenu = (ExpandableTableViewController*)[mainStoryboard instantiateViewControllerWithIdentifier:@"sideMenu"];

      self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
      self.window.rootViewController = navigation;
      [self.window makeKeyAndVisible];

  }else
   {

      LoginViewController *loginVC=[mainStoryboard instantiateViewControllerWithIdentifier:@"LoginId"];

      self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
      self.window.rootViewController = loginVC;
      [self.window makeKeyAndVisible]; 
}

 return YES;

}

And in LoginViewController class, I have written code

- (IBAction)loginButtonMethod:(id)sender {
    [self->userdefaults setBool:YES forKey:@"loginSuccess"];

    InboxView *inboxVC=[self.storyboard  instantiateViewControllerWithIdentifier:@"id1"];
    [self.navigationController pushViewController:inboxVC animated:YES];
    [[self navigationController] setNavigationBarHidden:NO];
}

Answer 1

Try this. ProductVC is your class where you want to push

NSString * storyboardName = @"Main";
        NSString * viewControllerID = @"id3";
        UIStoryboard * storyboard = [UIStoryboard storyboardWithName:storyboardName bundle:nil];
        ViewController3 * controller = (ViewController3 *)[storyboard instantiateViewControllerWithIdentifier:viewControllerID];

        UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController: controller];
        [navController setViewControllers: @[controller] animated: YES];
        [self.revealViewController setFrontViewController:navController];
        [self.revealViewController setFrontViewPosition: FrontViewPositionLeft animated: YES];

So like this you can move to any class, in didselectrowatindexpath just put validation for which row you want which class to push.

Answer 2

Please write your parent navigation code in following method . For child view

- (void)ftFoldingTableView:(FTFoldingTableView *)ftTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSLog(@"indexPath--->%ld",(long)indexPath.row);
    //Write your  push next view controller code 
    [ftTableView deselectRowAtIndexPath:indexPath animated:YES];
}

Write parent view navigation code following method

- (void)ftFoldingTableView:(FTFoldingTableView *)ftTableView willChangeToSectionState:(FTFoldingSectionState)sectionState section:(NSInteger)section
{
    NSLog(@"section-->%ld",(long)section);
// Write push level 0 or parent view move next view controller code 

   // NSLog(@"section: %ld is about to %@", section, sectionState == FTFoldingSectionStateFold ? @"close" : @"open");
}

Try this code working properly

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    //check if the row at indexPath is a child of an expanded parent.
    //At a time only one parent would be in expanded state
    NSInteger indexSelected = indexPath.row;
    NSDictionary *dicSelected  =[self.itemsInTable objectAtIndex:indexSelected];
    /**
     Resolved the issue of top line separator dissapearing upon selecting a row (hackishly) by reloading the selected cell
     */
    @try {
        [self.menuTableView reloadRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
    }
    @catch (NSException *exception) {
    }

    [tableView setSectionIndexBackgroundColor:[UIColor blackColor]];
    //
    //Collapse any other expanded cell by iterating through the table cells.
    //Don't collapse if the selected cell is a child of an expanded row.
    NSDictionary *dicCellToCollapse  =[self.itemsInTable objectAtIndex:g_ExpandedCellIndex];
    NSInteger numRowsCollapsed = 0;
    NSInteger level = [[dicSelected valueForKey:@"level"] integerValue];

    if(level==0 && [dicCellToCollapse valueForKey:@"SubItems"] && (g_ExpandedCellIndex != indexPath.row))
    {
        NSArray *arr=[dicCellToCollapse valueForKey:@"SubItems"];
        BOOL isTableExpanded=NO;

        for(NSDictionary *subitems in arr )
        {
            NSInteger index=[self.itemsInTable indexOfObjectIdenticalTo:subitems];
            isTableExpanded=(index>0 && index!=NSIntegerMax);
            if(isTableExpanded) break;
        }
        //
        //Collapse the parent cell if its expanded
        if(isTableExpanded)
        {
            [self CollapseRows:arr];
            numRowsCollapsed = [arr count]-1;
        }
    }

    //
    //go about the task of expanding the cell if it has subitems
    NSDictionary *dic;
    if (g_ExpandedCellIndex < indexPath.row && numRowsCollapsed)
    {
        dic = [self.itemsInTable objectAtIndex:indexPath.row-numRowsCollapsed-1];

    else
