【问题描述】：

我正在翻译我的应用程序，但我遇到了远程通知问题。以下文档

在您的 App Bundle 中存储本地化内容

如果您对通知使用一致的消息集，您可以在您的应用程序包中存储消息文本的本地化版本并使用有效载荷中的 loc-key 和 loc-args 键来指定哪个要显示的消息。 loc-key 和 loc-args 键定义消息通知的内容。当存在时，本地系统搜索应用程序的 Localizable.strings 文件，用于匹配与锁定键中的值。然后它使用来自字符串文件作为消息文本的基础，替换任何具有由 loc-args 键指定的字符串的占位符值。（您也可以使用 title-loc-key 和 title-loc-args 键。）

我有 NSLocalizedString 的标题、副标题和正文。问题是，当我从英语设置设备发送通知时，我会在意大利语设置设备上收到英语远程通知。我将所有Localized key:value 对存储在Localizable.string 文件中，以便我理解它可以工作，在收到通知时，应从Localizable.string 文件中获取当前设备语言的值并显示。我对所有警报小狗都这样做，它在那里完美地工作，但在远程通知上，它保持发送设备的语言。我将 FCM 用于远程通知，所以我可能会错过在有效负载中传递一些值。你能看到有效载荷中缺少什么吗？非常感谢。

static func sendPushNotification(to receiverToken: String, title: String, subtitle: String, body: String) {
        print("PushNotifications.sendPushNotification Started")
        let serverKey = firebaseServerKey
        let url = NSURL(string: "https://fcm.googleapis.com/fcm/send")

        let postParams: [String : Any] = [
            "to": receiverToken,
            "mutable_content": true,
            "content_available": true,
            "priority": "high",
            "notification": [
                //                    "badge" : 1, sendig the badge number, will cause aglitch
                // receiving device localized parameters
                "title_loc_key" : title,
                "subtitle_loc_key" : subtitle,
                "body_loc_key" : body,
                "sound" : true, // or specify audio name to play
            ],
            "data" : [
                "data": "ciao",
            ]
        ]

        let request = NSMutableURLRequest(url: url! as URL)
        request.httpMethod = "POST"
        request.setValue("key=\(serverKey)", forHTTPHeaderField: "Authorization")
        request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")

        do {
            //                request.httpBody = try JSONSerialization.data(withJSONObject: postParams, options: JSONSerialization.WritingOptions())
            request.httpBody = try JSONSerialization.data(withJSONObject: postParams, options: [.prettyPrinted]) // working
            print("My paramaters: \(postParams)")
        } catch {
            print("Caught an error: \(error)")
        }

        let task = URLSession.shared.dataTask(with: request as URLRequest) { (data, response, error) in
            if let realResponse = response as? HTTPURLResponse {
                if realResponse.statusCode != 200 {
                    print("Not a 200 response")
                }
            }




            if let posData = data {
                if let postString = String(data: posData, encoding: String.Encoding(rawValue: String.Encoding.utf8.rawValue)) as String? {
                    print("POST: \(postString)")
                }
            }
        }

        task.resume()
    }

这是函数调用：

PushNotifications.sendPushNotification(to: customerFcmToken, title: String(format: NSLocalizedString( "ORDER_DELETED_PUSH_TITLE", comment: ""), orderId), subtitle: String(format: NSLocalizedString( "ORDER_DELETED_PUSH_SUBTITLE", comment: ""), UserDetails.fullName!), body: String(format: NSLocalizedString("ORDER_DELETED_PUSH_BODY", comment: "") , customerName))

【解决方案1】：

我知道你打电话给我

PushNotifications.sendPushNotification(to: customerFcmToken, title: String(format: NSLocalizedString( "ORDER_DELETED_PUSH_TITLE", comment: ""), orderId), subtitle: String(format: NSLocalizedString( "ORDER_DELETED_PUSH_SUBTITLE", comment: ""), UserDetails.fullName!), body: String(format: NSLocalizedString("ORDER_DELETED_PUSH_BODY", comment: "") , customerName))

您正在执行本地化，而不是发送本地化密钥。

【讨论】：

你还需要 title_loc_args 和相同的字幕
确实是这样。面团我不得不将字符串格式更改为 %1@ 不被识别，但简单的 %@ 可以作为一种魅力。

【解决方案2】：

我发布了一个答案，以便为其他偶然发现此问题的人做一个很好的回顾。正如接受的答案中所述，主要问题是我传递了“本地化”String 而不是“参考”String 用于本地化以从正确的Localizable.string 文件中获取值。由于我的Localizable.string 字符串有格式，loc-args 也需要与有效负载一起传递，以便交换占位符的值。我有它们在%1@、%2@ 等形式，但正确的形式是简单的%@。所以修改后的代码是：

static func sendPushNotification(to receiverToken: String, title: String, titleArgs: [String], subtitle: String, subtitleArgs: [String], body: String, bodyArgs: [String]) {
        print("PushNotifications.sendPushNotification Started")
        let serverKey = firebaseServerKey
        let url = NSURL(string: "https://fcm.googleapis.com/fcm/send")

        let postParams: [String : Any] = [
            "to": receiverToken,
            "mutable_content": true,
            "content_available": true,
            "priority": "high",
            "notification": [
                //                    "badge" : 1, sendig the badge number, will cause aglitch
                // receiving device localized parameters
                "title_loc_key" : title,
                "title_loc_args" : titleArgs,
                "subtitle_loc_key" : subtitle,
                "subtitle_loc_args" : subtitleArgs,
                "body_loc_key" : body,
                "body_loc_args" : bodyArgs,
                "sound" : true, // or specify audio name to play
            ],
            "data" : [
                "data": "ciao",
            ]
        ]

        let request = NSMutableURLRequest(url: url! as URL)
        request.httpMethod = "POST"
        request.setValue("key=\(serverKey)", forHTTPHeaderField: "Authorization")
        request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")

        do {
            //                request.httpBody = try JSONSerialization.data(withJSONObject: postParams, options: JSONSerialization.WritingOptions())
            request.httpBody = try JSONSerialization.data(withJSONObject: postParams, options: [.prettyPrinted]) // working
            print("My paramaters: \(postParams)")
        } catch {
            print("Caught an error: \(error)")
        }

        let task = URLSession.shared.dataTask(with: request as URLRequest) { (data, response, error) in
            if let realResponse = response as? HTTPURLResponse {
                if realResponse.statusCode != 200 {
                    print("Not a 200 response")
                }
            }

            if let posData = data {
                if let postString = String(data: posData, encoding: String.Encoding(rawValue: String.Encoding.utf8.rawValue)) as String? {
                    print("POST: \(postString)")
                }
            }
        }

        task.resume()
    }

它被称为：

PushNotifications.sendPushNotification(to: customerFcmToken, title: "BOOKING_DELETED_PUSH_TITLE", titleArgs: [self.bookingId], subtitle: "BOOKING_DELETED_PUSH_SUBTITLE", subtitleArgs: [UserDetails.fullName!], body: "BOOKING_DELETED_PUSH_BODY", bodyArgs: [customerName])

再次感谢您。
