ios - Swift didReceiveRemoteNotification - 无论应用用户位于何处，都导航到 rootviewcontroller(现在有错误消息)

Question

在 IOS Swift 应用程序中收到推送通知后，我想根据通知中的内容做两件事:

1. 要么导航到屏幕(深层链接)，这样我就必须从 rootviewcontroller 导航到多个屏幕。

2. 无论用户位于应用中的哪个位置，都导航到 rootviewcontroller。

我认为第二个是第一个的先决条件。

我知道我需要在这两个函数中放置代码:

• didReceiveRemoteNotification
• didReceiveLocalNotification

错误信息:“UIViewcontroller？”没有名为“navigationController”的成员

在 AppDelegate.swift 文件中:

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) 
{
    println("didReceiveRemoteNotification")
    //Navigate to rootviewcontroller
    var rootViewController = self.window!.rootViewController
    let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    var setViewController = mainStoryboard.instantiateViewControllerWithIdentifier("CurrentShows")
        as ViewController

    //rootViewController.navigationController?
    //    .popToViewController(setViewController, animated: false)
}

Answer 1

在你的方法中尝试这段代码:

var rootViewController = self.window!.rootViewController
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)

var setViewController = mainStoryboard
    .instantiateViewControllerWithIdentifier("CurrentShows")
        as ViewController_CurrentShows

rootViewController
    .navigationController
    .popToViewController(setViewController, animated: false)
