Question

我有一个Webview ios应用程序，该应用程序接收通知，并传递一个url，以便用户单击通知时，它将打开该URL的webview。

当应用程序在前台和后台运行时，它可以正常工作。如果用户在应用程序关闭且当前未运行时收到通知，则该应用程序将打开，但不会转到该网址

在我的didReceiveRemoteNotification中，我检测到应用程序的不同状态，但我认为.background的工作原理与未运行相同，但我猜不行。关闭应用程序后，如何获取打开URL的通知？

AppDelegate.swift

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {

    let data = userInfo as! [String: AnyObject]
    let state = UIApplication.shared.applicationState
    if state == .background {
        // background
        //print("==== Active Running ====")
        if let aps = data["aps"] {
            let url = aps["url"]
            viewController?.loadRequestnotification(for: url as! String)
        }
    }
    else if state == .inactive {
        // inactive
        //print("==== Inactive Running ====")
        if let aps = data["aps"] {
            let url = aps["url"]
            viewController?.loadRequestnotification(for: url as! String)
        }
    }

}

更新

因此，在一些帮助下，我已经能够使用didFinishLaunchingWithOptions来调用我的Web视图，但是在按下时的通知仍未打开该URL。

我在我的代表的其他一些区域使用viewController?.loadRequestnotification(for: url as! String)正常工作。我怀疑return true可能与通话冲突。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    UNUserNotificationCenter.current().delegate = self
    ConnectionManager.sharedInstance.observeReachability()
    // Override point for customization after application launch.
    FirebaseApp.configure()
    registerForPushNotifications()

    if launchOptions != nil {
        // opened from a push notification when the app is closed
        let userInfo = launchOptions?[.remoteNotification] as? [AnyHashable : Any]
        if userInfo != nil {
            if let object = userInfo?["aps"] as? [String : AnyObject] {
                let url = object["url"]
                viewController?.loadRequestnotification(for: url as! String)
            }
        }
    }
    return true
}

didReceiveRemoteNotification。

在您的应用关闭时尝试使用此代码以获取通知数据。

  func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
     if launchOptions != nil {
       // opened from a push notification when the app is closed
        let userInfo = launchOptions?[.remoteNotification] as? [AnyHashable : Any]
       if userInfo != nil {
       if let object = userInfo?["aps"] {
           let url = object["url"]")
          // Now set root controller here
       }
     }
  } else {
     // opened app without a push notification.
         }
  }

有一种情况，例如您的应用未运行，并且用户单击应用的通知，然后按照获取方式进行操作。

这是您可以获取的代码

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {


    if let notification = launchOptions?[.remoteNotification] as? [String: Any] {
        if let dictionary:NSDictionary = notification as? NSDictionary{
            print("Dictionary Print in didFinishLaunching :: \(dictionary)")
        }
    }

}

您的应用程序可以收到一些通知，它位于通知中心，但是用户无法单击任何通知，但是他们会像平常一样打开您的应用程序，然后通过以下方法，您可以获取您的接收到的所有通知应用。

UNUserNotificationCenter.current().getDeliveredNotifications { (notification) in
        print(notification.count)

    }

Answer 3

这是当应用收到任何通知时调用的函数。我已经在聊天应用程序中使用了它。

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    if application.applicationState == .active {
        //Application is currently active and user receive the notification
    } else if application.applicationState == .background {
        //app is in background, but not killed
    } else if application.applicationState == .inactive {
        //app is transitioning from background to foreground (user taps notification), do what you need when user taps here
        //Load your URL into webView from here
    }
}

如果应用已打开，并且您希望在收到通知时执行某些操作使用这种方法

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    completionHandler(UNAuthorizationOptions.alert.rawValue | UIUserNotificationType.sound.rawValue | UIUserNotificationType.badge.rawValue)
}

您还可以通过通知查看应用是否打开的天气 AppDelegate's didFinishLaunchingWithOptions

但是建议将此didFinishLaunchingWithOptions方法保持尽可能浅。我希望这对您有用
