禁用頂部導航欄

Question

我正在嘗試處理遠程通知。 在我的AppDelegate didReceive方法，我想開一看：

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) 

這是工作，但不顯示在頂部導航欄。所以用戶不能上一個。

我該怎麼辦？我想：

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

但它不工作

編輯：

它的工作有：

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 

由於拉雅

Answer 1

更改此

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

與此

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

由於這個問題是，您是在陳述你UIViewController上的window的rootViewController，所以這ViewController是您UINavigationController的頂部。
