iOS 具有多个目标的通知服务扩展从不调用扩展方法

iOS Notification Service Extension with multiple targets never calls extension methods

我目前正在尝试使用 Notification Service Extension 作为在 push notification payload 中未获得有效徽章计数的应用程序的解决方法。为了解决这个问题,我想我会创建一个通知服务扩展来跟踪已收到的消息数量,并相应地跟踪计数。上周我开始工作了,现在我继续工作,但它不再工作了,我不知道为什么会这样。

正在根据目标更改 Notification Service Extension 包 ID。对于我拥有的 2 个目标,这个预构建脚本看起来像这样

buildID=${PRODUCT_BUNDLE_IDENTIFIER}
extId="AppPushNotification"

/usr/libexec/PlistBuddy -c "Set :CFBundleIdentifier $buildID.$extId" "${SRCROOT}/${extId}/Info.plist"

我在扩展程序中使用的代码

import UIKit
import UserNotifications

class NotificationService: UNNotificationServiceExtension {

    var contentHandler: ((UNNotificationContent) -> Void)?
    var bestAttemptContent: UNMutableNotificationContent?

    override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) {
        self.contentHandler = contentHandler
        bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent)

        if let bestAttemptContent = bestAttemptContent {
            // Modify the notification content here...
            let userDefaults = UserDefaults.init(suiteName: "group.com.my.bundle.notification-service-extension")
            let unreadMessages = userDefaults?.integer(forKey: "unreadMessages")
            let newUnreadMessages = unreadMessages != nil ? unreadMessages! + 1 : 0

            bestAttemptContent.title = "\(bestAttemptContent.title) [modified]"
            bestAttemptContent.badge = NSNumber(value: newUnreadMessages)
            let userInfo = bestAttemptContent.userInfo
            guard let info = userInfo["aps"] as? [AnyHashable: Any],
                let data = info["data"] as? [AnyHashable: Any],
                let chatId = data["chatId"] as? String else { return }

            let unreadMessagesInChat = userDefaults?.integer(forKey: chatId)
            let newUnreadMessagesInChat = unreadMessagesInChat != nil ? unreadMessagesInChat! + 1 : 0

            userDefaults?.set(newUnreadMessages, forKey: "unreadMessages")
            userDefaults?.set(newUnreadMessagesInChat, forKey: chatId)


            contentHandler(bestAttemptContent)
        }
    }

    override func serviceExtensionTimeWillExpire() {
        // Called just before the extension will be terminated by the system.
        // Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
        if let contentHandler = contentHandler, let bestAttemptContent =  bestAttemptContent {
            contentHandler(bestAttemptContent)
        }
    }

}

我正在使用 Pusher 推送我的测试通知负载。我发送的负载:

{
   "aps":{
      "mutalbe-content":1,
      "content-available":1,
      "sound":"true",
      "alert":{
         "title":"Vera Pauw",
         "body":"test bericht"
      },
      "data":{
         "type":"test",
         "message":"test bericht",
         "chatId":"3b002aa6-1117-4206-b54f-8bc2bd689f1c",
         "fromId":"",
         "fromname":"Vera Pauw"
      }
   }
}

我成功收到通知,但从未触发过扩展代码。我尝试过多种调试方式,比如在 运行 应用程序之后选择调试目标,或者 运行 来自扩展目标的应用程序,但是 Notification Service 的过程总是会说 Waiting to Attach。我试过使用我的推送通知负载,但这并没有改变结果。

有谁知道为什么会这样或者我哪里出错了。

您的通知负载肯定是问题的一部分。 在你的问题中,有效载荷是:

{
   "aps":{
      "mutalbe-content":1,
      "content-available":1,
      "sound":"true",
      "alert":{
         "title":"Vera Pauw",
         "body":"test bericht"
      },
      "data":{
         "type":"test",
         "message":"test bericht",
         "chatId":"3b002aa6-1117-4206-b54f-8bc2bd689f1c",
         "fromId":"",
         "fromname":"Vera Pauw"
      }
   }
}

aps 密钥应该只包含 Apple 的密钥。您的 data 词典应该在 aps 键之外。

如果有 alertbuttonsound 键,则 "content-available" 不应出现 - 通知不能同时静音 面向用户。 content-available 仅适用于静默通知。

"mutalbe-content" 键也拼写错误,这就是您的扩展未被激活的原因!

我看到很多人有同样的问题所以我写了a simple push notification validation tool you can use to troubleshoot these problems

根据您尝试完成的内容,更正后的负载可能如下所示:

{
   "aps":{
      "mutable-content":1,
      "alert":{
         "title":"Vera Pauw",
         "body":"test bericht"
      }
   },
  "data":{
     "type":"test",
     "message":"test bericht",
     "chatId":"3b002aa6-1117-4206-b54f-8bc2bd689f1c",
     "fromId":"",
     "fromname":"Vera Pauw"
  }
}

试试看扩展是否启动。
