ios - 为什么我无法在 iOS 10 中处理收到的推送通知？

Question

我已经导入了

import UserNotifications

和连接的代表:

UNUserNotificationCenterDelegate

并将委托(delegate)设置为自己:

UNUserNotificationCenter.currentNotificationCenter().delegate = self
FIRMessaging.messaging().remoteMessageDelegate = self

最后我有这些功能:

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, willPresentNotification notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
    //Handle the notification
    print("User Info = ",notification.request.content.userInfo)
    completionHandler([.Alert, .Badge, .Sound])
}

@available(iOS 10.0, *)
func userNotificationCenter(center: UNUserNotificationCenter, didReceiveNotificationResponse response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
    //Handle the notification
    print("User Info = ",response.notification.request.content.userInfo)
    completionHandler()
}

但是当我在真实设备上和后台模式下测试时，我的日志上没有任何打印。

问题是什么？

internal func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    print(userInfo)

    // Print message ID.
    print("Message ID: \(userInfo["gcm.message_id"]!)")
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                 fetchCompletionHandler completionHandler: (UIBackgroundFetchResult) -> Void) {        
    // Print message ID.
    print("Message ID: \(userInfo["gcm.message_id"]!)")

    // Print full message.
    print(userInfo)
}

请尝试使用以下代码。您只需要保存数据。

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> ())
{
     let info : NSDictionary! = userInfo as! NSDictionary

     if info != nil
      {
          let aps = info["aps"] as? NSDictionary
          UserDefaults.standard.set(aps, forKey: "aps")
       }
   }

并在您想使用的地方使用用户默认值。
