ios - Swift 4 - 带有标签栏和导航 Controller 的 3D Touch 快速操作

Question

我正在尝试从主屏幕添加 3D Touch Quick Actions，我正在使用以下代码:

        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let tabVC = storyboard.instantiateViewController(withIdentifier: "TabVC") as! UITabBarController
        let mainVC = storyboard.instantiateViewController(withIdentifier: "NavMoreVC") as! UINavigationController
        let foodVC = storyboard.instantiateViewController(withIdentifier: "FoodVC") as! FoodTableViewController
        window?.rootViewController = tabVC
        self.window?.makeKeyAndVisible()
        mainVC.pushViewController(foodVC, animated: true)

我试图在用户点击快捷方式后导航到 Find Food View Controller ，但上面的代码在控制台中给我一个错误:

Unbalanced calls to begin/end appearance transitions for <UITabBarController: 0x10e022600>.

有没有一种方法可以让应用在保持标签栏和导航 Controller 的同时推送到 Find Food View Controller 。谢谢!!

Answer 1

进行了更多挖掘并找到了解决方案。我在 AppDelegate 中使用了以下代码:

    let myTabBar = self.window?.rootViewController as? UITabBarController
    myTabBar?.selectedIndex = 0
    let nvc = myTabBar?.selectedViewController as? UINavigationController
    let vc = nvc?.viewControllers.first as? MoreViewController
    nvc?.popToRootViewController(animated: false)
    return vc!.openPageFor(shortcutIdentifier: shortcutIdentifier)

然后在我的 MoreViewController 中，我有一个函数可以根据 shortcutIdentifier 调用不同的 segues。
