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];
}

在自定义单元格中，TableCategoryCell.m包含collectionView。

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

现在我希望用户点击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];
}

我可以从故事板中的集合项推送ViewController2，但我不知道在编程中？我该怎么办？

为uicollection视图实现委托方法：

- (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];
    }   

}

将数据从自定义tablecell中的uicollectionview传递给viewcontroller
