How to use SWRevealVC with didSelectRowAtIndexPath and prepareForSegue?

Question

I have a problem with using SWRevealViewController. How to call prepare for segue in didSelectRowAtIndexPath? It is necessary because in tableView I have name of categories and some of this categories have its own subcategories. For example my list:

- category1
- category2
+ category3
- category4

So, when I click on + category3 I should see

- category1
- category2
+ category3
  - subcategory1
  - subcategory2
- category4

But I could not to do this because of prepareForSegue Here is my code:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    if (indexPath.section <= _categories.count) {
        GDCategory *category = [[_subCategories objectAtIndex:indexPath.section] objectAtIndex:indexPath.row];
        _gdCategory = category;
        if (category.subcategories.count > 0) {
            NSNumber *categoryId = @(category.dbId);
            if ([_selectedSubCategories containsObject:categoryId]) {
                [_selectedSubCategories removeObject:categoryId];
            } else {
                [_selectedSubCategories addObject:categoryId];
            }
            NSLog(@"There are %lu subcategories in %@", (unsigned long)category.subcategories.count, category.name);
            [self recalcSubcategories];
            [tableView reloadData];
        } else {
            //Here I should call prepareForSegue
        }
        NSLog(@"selected category is %@", category.name);
    }
}

- (void)prepareForSegue: (UIStoryboardSegue *)segue sender:(id)sender {
    // configure the destination view controller:
    if ( [sender isKindOfClass:[UITableViewCell class]] ) {
        UINavigationController *navController = segue.destinationViewController;
        GDCategoryVC *categoryVC = [navController childViewControllers].firstObject;
        if ( [categoryVC isKindOfClass:[GDCategoryVC class]] ) {
            categoryVC.selectedCategory = _gdCategory;
        }
    }
}

Also, I could not to pass data throw VCs, because prepareForSegue call firstly. Please help me. Thanks!

Answer 1

//in prepareForSegue method

NSIndexPath *indexPath = [tableView indexPathForSelectedRow];

and you can get selected row value by using indexPath.row
