我指的是来自 GitHub 的项目。

我正在尝试根据我的要求对其进行修改，但我没有得到并且无法理解我必须在didSelectRowAtIndexPath方法中编写什么代码。

这是图像

我想要的是在单击 tableView 行后它可以是 0 级或 1 级(here level 0 means - row has no sub child and level 1 means row has subview/child rows )

当我单击级别 0 或级别 1 的任何 tableView 行时，它必须导航到下一个 viewController。

在此示例中，第 2 行和第 3 行是可扩展的，即它包含 1 级行，第 0、1、4 和 5 行是它们不扩展的第 1 级行。

这是项目链接（更新的项目链接）

***** 添加代码 ****

我在 AppDelegate 类中编写的代码，

- (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;

}

在 LoginViewController 类中，我编写了代码

- (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];
}

尝试这个。ProductVC 是你想要推送的类

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];

所以像这样你可以移动到任何类，在 didselectrowatindexpath 中只需验证你想要哪个类推送的行。

请按以下方法编写您的父导航代码。对于子视图

- (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];
}

编写父视图导航代码如下方法

- (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");
}

尝试此代码正常工作

-(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"];
