ios - 当我的应用程序处于后台或关闭状态时，远程推送通知到达时从负载获取数据

Question

当收到远程推送通知时，我需要从有效负载中捕获数据，在 IOS 9 上我使用 func 做到了这一点: didReceiveRemoteNotification 在使用 swift 3.0 的 IOS 10 上，我已经实现了这两个功能。

@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

当我的应用程序处于后台甚至关闭时收到推送通知时，我需要捕获数据。

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

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!
    }
}
