ios - 如何将数据从 Collection View 单元格传递到新的 View Controller (以编程方式且无需 Storyboard)？

Question

我在将数据从 Collection View 单元格传递到新 View Controller 时遇到问题。我有 Collection View 单元格，每个单元格都有图像和标签，我想为每个单元格创建新的 View Controller 。

我已经尝试过 UINavigationController 但目前和 navigationController 代码在 didSelectItemAt indexPath 函数下不起作用。每个人都用 Storyboard做到了这一点，但我没有使用它，而且我找不到解决方案。

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    print("#\(indexPath.item)!")
    //let cell = collectionView.cellForItem(at: indexPath) as! itemsCell
    //let cell = itemler[indexPath.row]

    let newView = UINavigationController(rootViewController: orderBasketController())
    self.present(newView, animated: true, completion: nil)
}

代码出现错误，类型“feedCell”的值没有成员“present”。

尝试在 init 方法中注入(inject)依赖项以查看 Controller 。

    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        guard let yourCell = collectionView.cellForItem(at: indexPath) as? YourCellClass else {
            return
        }
        let yourModel = Model(title: yourCell.title, image: yourCell.image)
        let targetViewController = TargetViewController(model: yourModel)
        navigationController?.pushViewController(targetViewController, animated: true)
        // or if it's not in navigation controller
        // present(targetViewController, animated: true, completion: nil)
     }
