将自定义表格中的uicollectionview数据传递给视图控制器

Question

我遇到问题。我有一个ViewController1包含tableView.that的tableView创建自定义tableViewCell

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

在TableCategoryCell.m包含的CollectionView自定义单元格。

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

现在我想用户点击的CollectionView项didSelectItemAtIndexPath方法打开新ViewController2和数据传递到视图控制器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]; 
} 

我可以在故事板从集合项目推ViewController2但我不知道在编程？ 我该怎么办？

实施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]; 
    } 

}
