【问题描述】：

接收远程推送通知时，我需要从有效负载中捕获数据，在 ios 9 上，我使用 func 执行此操作： didReceiveRemoteNotification 在使用 swift 3.0 的 IOS 10 上，我实现了这两个功能。

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)

print("\(notification.request.content.userInfo)")

completionHandler([.alert, .badge, .sound])


@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)

print("User Info = ",response.notification.request.content.userInfo)

completionHandler()

第二个函数仅在用户触摸推送时执行

当我的应用处于后台甚至关闭时，当推送通知到达时，我需要捕获数据。

问候。 问候

【参考方案1】：

当收到推送通知并且您的应用未运行时，您需要在 didFinishLaunchingWithOptions 中实现通知逻辑：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool 
   // Called when a notification is tapped and the app wasn't running, not in foreground neither in background. 
   if let userInfo = launchOptions?[UIApplicationLaunchOptionsKey.remoteNotification] as? [String: AnyObject]
        // your logic here!
    

【参考方案2】：

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

    // Capture payload here something like:
    let appState = userInfo["appState"] as? String
    print(appState!)

    // Do something for every state
    if (application.applicationState == UIApplicationState.active)
        print("Active")

    else if (application.applicationState == UIApplicationState.background)
        print("Background")


    else if (application.applicationState == UIApplicationState.inactive)
        print("Inactive")

    

    completionHandler(.noData)

【参考方案3】：

试试iOS10的didReceiveRemoteNotification功能：

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) 

                   print(userInfo)

             

【讨论】：

嗨，我做到了，并且我能够在 aps content-available=1 上的后台 sendind 中从推送通知中捕获数据。但是当应用程序关闭时，它似乎永远不会执行。

嘿@Christian Gonzalez，如果用户自己关闭或终止应用程序，那么我们不能做这样的事情。
