【问题描述】：

为了让它发挥作用，我绞尽脑汁想了一天。我收到了通知，但在单击时从未导航到特定选项卡。

    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                      didReceive response: UNNotificationResponse,
                                      withCompletionHandler completionHandler: @escaping () -> Void) 
            let userInfo = response.notification.request.content.userInfo
        
            // Print message ID.
            if let messageID = userInfo[gcmMessageIDKey] 
              print(tag + "Message ID: \(messageID)")
            
            
            // With swizzling disabled you must let Messaging know about the message, for Analytics
            // Messaging.messaging().appDidReceiveMessage(userInfo)
            // Print full message.
            print(userInfo)
            
        //    let myTabBar = self.window?.rootViewController as? UITabBarController
        //    myTabBar?.selectedIndex = 2
            
            //TabBarController - StoryBoard Id
            let storyboard = UIStoryboard(name: "Main", bundle: nil)
            if let tabController = storyboard.instantiateViewController(withIdentifier: "TabBarController") as? UITabBarController 
                tabController.selectedIndex = 2
            
        
            completionHandler()
          

【参考方案1】：

对于使用 Swift 的 ios 14.4。 在其他问题的帮助下，这最终对我有用。

    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                  didReceive response: UNNotificationResponse,
                                  withCompletionHandler completionHandler: @escaping () -> Void) 
        let userInfo = response.notification.request.content.userInfo
    
        // Print message ID.
        if let messageID = userInfo[gcmMessageIDKey] 
          print(tag + "Message ID: \(messageID)")
        
        
        // With swizzling disabled you must let Messaging know about the message, for Analytics
        // Messaging.messaging().appDidReceiveMessage(userInfo)
        // Print full message.
        print(userInfo)
        
        let scene = UIApplication.shared.connectedScenes.first
            if let sceneDelegate = scene?.delegate as? SceneDelegate 
                if let tabController = sceneDelegate.window?.rootViewController as? UITabBarController 
                      tabController.selectedIndex = 2
                
    
            
        
        print("Clicked Notification")
    
        completionHandler()

这很好用，我喜欢你从 uiapplication 中提取它的方式。 selectedIndex 2 的 ViewController 是一个导航控制器，但我在执行 pushViewController 时遇到问题。有什么想法吗？我要显示的视图是在 tabController.selectedIndex 2 中显示的列表视图上推送的详细视图

@Maddocks 我不太明白你的问题。当我有时间时，我需要查看一些代码来帮助你。希望你解决你的问题伙伴。

tabController.selectedIndex = 2 guard let vc = tabController.selectedViewController as? UINavigationController else return vc.popToRootViewController(animated: true) DetailsVC = uistoryboard.init(...).instantiateViewController(...) DetailsVC.datasource = ... vc.pushViewController(DetailsVC, animated: true) // this is how i work with a tab view and a nav view

【参考方案2】：

对于导航到特定的 ViewController，我使用了这个扩展

public extension UIApplication 
    class func getTopViewController(base: UIViewController? = UIApplication.shared.keyWindow?.rootViewController) -> UIViewController? 
        
        if let nav = base as? UINavigationController 
            return getTopViewController(base: nav.visibleViewController)
            
         else if let tab = base as? UITabBarController, let selected = tab.selectedViewController 
            return getTopViewController(base: selected)
            
         else if let presented = base?.presentedViewController 
            return getTopViewController(base: presented)
        
        return base
    

那就叫它如下：

  func userNotificationCenter(_ center: UNUserNotificationCenter,
                              didReceive response: UNNotificationResponse,
                              withCompletionHandler completionHandler: @escaping () -> Void) 
    let userInfo = response.notification.request.content.userInfo

    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] 
      print(tag + "Message ID: \(messageID)")
    
    
    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)
    // Print full message.
    print(userInfo)
    
     let storyboard = UIStoryboard(name: "yourStoryboardName", bundle: nil)
        let vc = storyboard.instantiateViewController(withIdentifier: "yourStoryboardId") as! YourViewcontroller
        //                   vc.nNotificationID = notificationID
        
        if let topVC = UIApplication.getTopViewController() 
            topVC.navigationController?.pushViewController(vc, animated: false)
        
    
    print("Clicked Notification")

    completionHandler()

我已经解决了我的问题。我还没有尝试过你的代码，但它看起来很有希望。感谢您的努力。
