将数据从自定义表格单元中的 uicollectionview 传递到 viewcontroller

Question

我有问题。我有一个 ViewController1 包含一个 tableView.that tableView 创建一个自定义 tableViewCell

-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
    TableCategoryCell *cell = (TableCategoryCell *)[tableView dequeueReusableCellWithIdentifier:CategoryCellIndentifier];
}

在自定义单元格 TableCategoryCell.m 中包含一个 collectionView。

-(UICollectionViewCell*)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
    UICollectionViewCell *cell_collection = [collectionView dequeueReusableCellWithReuseIdentifier:COLLECTION_CELL_IDENTIFIER forIndexPath:indexPath];
}

现在我希望用户单击 didSelectItemAtIndexPath 方法中的 collectionView 项打开新的 ViewController2 并将数据传递给 ViewController 2？

-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    UINavigationController *navigationController =[storyboard instantiateViewControllerWithIdentifier:@"Navigation"];
    ViewController2 *watchController = [storyboard instantiateViewControllerWithIdentifier:WATCH_IDENTIFIER];
    [navigationController pushViewController:watchController animated:YES];
}

我可以从情节提要的集合项中推送 ViewController2，但我不知道在编程中？ 我该怎么办？

实现 uicollection 视图的委托方法：

- (void)tableView:(UICollectionView *)tableView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
   //check if you tap on cell 1
    if(inderPath.row==0){
             //then push to second view controller
            UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard"
                                                     bundle: nil];
          SecondViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:@"your-second-view-controller-ID"];
      [self.navigationController pushViewController:viewController animated:YES];
    }   

}
