顶部导航栏已禁用

Question

我正在尝试处理远程通知。 在AppDelegate的didReceive方法中，我试图打开一个视图：

var storyboard = UIStoryboard(name: "Main", bundle: nil)
        var destinationController = storyboard.instantiateViewController(withIdentifier: "InfoTraficViewController") as? InfoTraficViewController
        destinationController?.infoTraficId = trafficInfoId
        window?.rootViewController?.present(destinationController!, animated: true, completion: nil)

这是可行的，但未显示顶部导航栏。 因此用户无法继续前进。

我能做什么 ？ 我试过了 ：

self.navigationController?.setNavigationBarHidden(false, animated: animated)

但这没用

编辑：

它正在与：

 var storyboard = UIStoryboard(name: "Main", bundle: nil)
    var destinationController = storyboard.instantiateViewController(withIdentifier: "InfoTraficViewController") as? InfoTraficViewController
    destinationController?.infoTraficId = trafficInfoId

    var customUiNavController = storyboard.instantiateViewController(withIdentifier: "CustomUINavigationController") as? CustomUINavigationController
    customUiNavController?.pushViewController(destinationController!, animated: true)

    window?.rootViewController = customUiNavController

Answer 1

改变这个

window?.rootViewController?.present(destinationController!, animated: true, completion: nil)

有了这个

self.navigationController?.pushViewController(destinationController, animated: true)

因为问题是，您正在将UIViewController呈现在window的rootViewController上，所以此ViewController在UINavigationController之上。
