混合程序化和故事板。单击按钮将不会在导航控制器中打开下一个 VC

Question

我有一个以编程方式构建的标签栏控制器。它看起来像这样：

class NewTabBarController: UITabBarController {

override func viewDidLoad() {
        super.viewDidLoad()

        self.delegate = self

        createTabbar()
    }

func createTabbar() {
let deliveryViewController = storyBoard.instantiateViewController(identifier: "DeliveryViewController") as? DeliveryViewController
        deliveryViewController?.tabBarItem.image = #imageLiteral(resourceName: "icon_deliver")
        deliveryViewController?.title = "Delivery"
        planDictionary["planType"] = Constants.Mealplan.deliveryPlan
        deliveryViewController?.planDictionary = planDictionary

// Excluded other tabs and view controller creations since they are the same
}

现在这个 DeliveryViewController 在故事板中创建并嵌入到导航控制器中

它有一个按钮点击动作：

@IBAction func saveNameButton(_ sender: UIButton) {



let addressViewController = storyBoard.instantiateViewController(identifier: "AddressViewController") as? AddressViewController
                addressViewController?.planDictionary = planDictionary
                navigationController?.pushViewController(addressViewController!, animated: true)
}

当标签栏在情节提要中时，按钮单击操作有效。但是在以编程方式重构之后，它不会将下一个 VC 放在导航堆栈上。

不胜感激。

几乎可以肯定...

这一行：

let deliveryViewController = storyBoard.instantiateViewController(identifier: "DeliveryViewController") as? DeliveryViewController

正在实例化 DeliveryViewController 的实例并将其设置为选项卡的视图控制器。但是你想要做的是加载一个UINavigationController并使DeliveryViewController成为该NavController的根视图控制器，并将该NavController设置为一个Tab项。
